More advanced wagonload goods operation- by wagon label.

Note: Post was written in July 2014 then left forgotten on the “drafts” pile for far too long. Apologies for that.

With Longest Day 2014 rapidly approaching, and memories of the fun we had with the “deck of cards” shunting game, thoughts turned to some form of operating challenge for those who wanted it this year. Since the long term ambition for the line is to simulate steam age goods operation as realistically as possible, it made sense to try out one of the standard methods keen Ops modellers use for this,either Car Card and Waybill (CC&WB) or Car Tag (wagon label) operation. The American nomenclature is no co-incidence. The emphasis on the larger layout Stateside (the ubiquity of large basements helping a great deal) means that layouts tend to represent lines rather than stations and since the scope for operating is so much greater, more people indulge so there is more trade support (both publications and products) to be had, and anyone looking into modelling ops is going to acquire a degree of familiarity with terms like Boxcar, Reefer, Gondola, and Peddler.

CC&WB is largely paper driven. Every wagon (car) has a corresponding card made from a thin piece of cardboard folded and glued to create a pocket. Upon this is written the vehicle number, type (tpyically using standardised abbreviations), owner, livery (and any other distinguishing marks to help identify it on the layout), and its home station. To “load” the car a small piece of paper known as a Waybill is drawn and inserted into the pocket in the card. The waybill represents a specific load, with a specific destination and will on it the load’s nature (including what type of wagon must be used to carry it), Origin, Destination (usually specifying both a town and a specific industry or facility) and a “next step” instruction. Wagons are marshalled into trains appropriate to load, priority and destination, and worked along the line, and the train crew take the cards with them (yes, crew: some operators find that rostering both a driver and a conductor/guard to this sort of train makes things both more efficient and more fun). Upon delivery the car-card is left at the appropriate station along with the wagon. At an appropriate time (usually the end of the day) someone (frequently the layout owner after the end of a session) checks each card and waybill, and follows the instruction thereon. REMOVE means remove the waybill- the wagon is now empty and should be worked back to its home station. TURN means the waybill has more than one step on it, so should be turned round or over so the next step shows, simulating a wagon that has been loaded or emptied and reloaded and now has a fresh destination. Once this is done, the card is replaced in the pile or box for that station. For added realism some operators maintain 3 boxes for each station; Arrival, Hold, and Departure (with possibly more to indicate direction). Cards are moved down from one box to another at predetermined intervals (simulating how long loading actually takes) and only those filed under Departure are considered ready to go and picked up by the next train travelling in the right direction.

Car Tag operation is altogether simpler, if perhaps a little less realistic. In this case a system of coloured and lettered/numbered tags is designed in advance, with colour and letter codings worked out to give a unique code to each possible destination (both on and off layout). These are applied to the actual model wagons, which are then worked to the correct destination accordingly. It is quick and simple to use, and easy to learn and understand but somewhat less realistic- both from the point of view of simulating real railway operations and from having brightly coloured thingies slapped conspicuously onto nicely painted, weathered and detailed wagons. It does however fulfill the primary requirement for goods operation, giving each wagon and train purpose and a specific destination.

I really like the idea of the CC&WB system, being drawn to its realism, flexibility (regular traffic or one off movements can be simulated, the paper acts as both “memory” and error correction, and once set up it can run virtually continuously with movement seamlessly following movement). It’s something I’d like to try in the longer term, but for now I ruled it out for three reasons. First, wagons have to be uniquely and indivudually identifiable which means numbering them, which means stencils, decals or hand-painting numbers on the lot (and that’s just the home fleet- visiting stock would either have to be individually numbered too or left out). Second: I suspect it would take a little longer to learn- not so good for the casual or once-a-year visitor. Finally, juggling the paperwork in one hand and a transmitter and water topup bottle in the other sounds like hard work, so perhaps not until ops days have enough regular support that we can roster guards.

That meant giving wagon labels a second look. In the smaller scales labels have to be overscale to be visible, and the more information they carry the bigger they have to be. 16mm scale is a different story, and for a comparatively simple railway like mine (by US Basement Empire standards), the information that matters could easily be contained in a scale-sized wagon label (maybe a little bigger for readability). Eventually proper label holders could be made from wire and fitted to the wagons, but for now blu-tac would be good enough (and allow participation of visiting rolling stock). The garden railway has four actual stations (and one more planned) to represent the eight on the Horncastle branch plus the junction at Wragby, so there are nine on-layout destinations. Since both Wragby and Horncastle represent junctions with other (un-modelled) railways off-layout destinations need representing too, both Lindsey Joint and “foreign”. Fortunately narrow gauge wagons travel no further than the trans-shipment sidings so the world beyond Lincolnshire doesn’t come into the picture. Off-layout destinations could be indicated by something as simple as general direction (West, North or East) but I think more detail helps bring the layout to life AND increases the operating challenge- “North” isn’t very interesting but “Blue-Yellow S3=Brumby” brings the railway beyond the garden to life, and gives people a challenge to meet: a wagon for Brumby has to get on the afternoon down Kirton pickup, so has to get to Market Rasen in time to couple to the mid-day Gainsborough mixed or be stuck in the sidings at Glentworth overnight.

After some doodling I decided to try a design using a combination of colours and lettering to pack as much information as possible into a small unobtrusive piece of paper. Each label was 8mm square, with a white circle separating a border from an inner coloured dot, upon which one letter and one number appeared. The whole label indicated a wagon’s destination: border colour indicated company (since six different companies owned by six different sixteen-millers are connected together to form the Lincolnshire narrow gauge network), dot colour indicated for which district within a company a wagon was bound, and the letter/number combination the individual station or industry. Thus a wagon bound for Horncastle would have a blue border (for Lindsey Joint), green inner dot (indicating Horncastle district) and be lettered H8. With hindsight, the H and the green dot both convey the same information, but only experience can tell whether that’s redundant or helpful.

At this point a rough guesstimate of likely traffic levels for each of the line’s stations was needed, so I used population data from an old copy of “Kelly’s Directory” and assumed traffic levels would be proportional to population. Thus 30% of wagons would go to intermediate stations, 40% to Horncastle and another 30% beyond to the WLLR (which actually serves a larger population but also has its own access to the standard gauge network at Firsby- so the LJR Horncastle line would have been lucky to get half the traffic). An appropriate amount of wagon labels for each station was drawn, printed, cut out and dropped in a plastic cup. Rather than select train length randomly, this time we started at Wragby (full of wagons) and assumed a 50-50 split between inward and outward traffic, so labelled every other wagon and let the train-crew loose.

With hindsight, this was a more complex system than the deck-of-cards game and would probably have benefitted from more time setting up and private practice before trying it out on guests.

The labels themselves were clear and easy to read, so operators had no trouble identifying the wagons they needed and making up trains.

Before the day I had printed out maps of the line and lap-count guides explaining where each station was on the system, and giving its unique label code.

The station layouts functioned exactly as designed, and shunting was practical, logical and realistic.

Blu-tac and paper was a painless way of including visiting rolling stock in the game, without which it wouldn’t have worked. Realism in freight traffic involves at least as many wagons standing around as on the move, so a lot of wagons are needed to simulate those stood waiting to load or unload.

The simpler deck-of-cards method only simulated shunting, so it was robust enough to be thrown into the mix of operators and free-for-all steamers at the 2013 event. The wagon label system, being more involved and realistic, was less robust. Shunting goods trains and circulating convoys of steamers got in each other’s way both on the main line and the stations, Horncastle in particular proving impossible to shunt as it was full of dead steamers and their trains.

Due to the haste with which the system was put together, there were a couple of proofing errors that proved both annoying and problematic. The worst was a simple typo, substituting H9 for an intended H8. Unfortunately H8 is the code for Horncastle, busiest station on the line and H9 does not exist. This created some embarassment on my part, and confusion on the part of the operators.

Paper labels are not very weatherproof. Even without rain, the damp of early morning in the shed has caused ink to run and paper to curl, quite quickly rendering the first batch useless.

One limitation of wagon labels is the lack of “what next”. Both sides of the label could be used, or the home station code could be displayed on a wagon (a tricky painting job if the size is to match)

Helpful hands cut up all the labels and put them in a pot. Unfortunately those helpful hands didn’t know the intricacies of the system so labels for incoming and outgoing traffic got mixed up, leading to a lot of scrabbling and discarding to find appropriate ones.

More proof-reading to eliminate silly mistakes.

Advance sorting of wagon labels for appropriate destinations (EG Horncastle doesn’t need any H8 labels to attach to wagons- why would it send a load to itself?)

More thought to go into the labels themselves. Print on both sides to give cyclic flows of traffic, or empty-in-loaded-out movements. Maybe use different border shapes to indicate load type or empty journeys. Laminate labels for weatherproofing and longevity. Use special labels (eg Red and Green defect cards, special labels for match, runner or barrier wagons).

A more permanent solution to attaching labels to the home fleet, most likely a simple bent-wire label holder for each wagon.

Signs “on the ground” indicating location and label code to help operators.

Integrate passenger and goods workings, thus allowing for the operation of tail traffic, mixed trains and specials at time of heavy demand. This means looking at air brake pipes for a select few wagons.

Most importantly, separate Operations from free-running. Plan and advertise separate “steamups” and “runnings” so each doesn’t get in the other’s way. Each on its own is too much fun to give up, but trying to do both at the same time doesn’t work.

Bluff your way in signalling: A quick (but 100% authentic) cheat.

As anyone who knows me in the hobby doubtless realises, I like signals and signalling. Full signalling and block working are on the long-term “to do” list for the railway, but with the twin spurs of the approaching 2014 “Longest Day” steamup and the presence of Victor Isle encouraging action, I needed something done right now. Inspiration came from an obscure note at the back of a history book about a minor standard gauge line, the Pilmoor Boroughbridge and Knaresborough Railway in Yorkshire, part of the North Eastern Railway. During the ’30s the LNER S&T department were under pressure to save money, and came up with an interesting scheme for light and minor railways to eliminate the costs of signalmen and lampmen.

The idea was that signalboxes and signals would be removed, and points converted to hand-lever operation with some key-locking. Signals would be replaced with fixed boards painted with dazzlingly conspicuous schemes by day, and with patterned reflectors by night, and unlit. This meant that locomotives would require powerful electric lights.

Approaching a block/staff post, a train would first encounter a “Location Marker Board”, 7’6″ x 1’6″ with black and white diagonal stripes (and a zigzag pattern of white reflectors). This was the equivalent of a distant signal fixed at caution, and warned the driver to start braking as they approached.

The next board encountered was the “Station Limit Board”, positioned outside the first pointwork and replacing the Home signal, this was 1’6″ x 6’3″ and painted with red and white diagonal stripes (and a reflector pattern of a white rectangular border with 3 evenly spaced red circular clusters inside). The meaning of this was the same as a STOP board, effectively “Stop at this board unless/until signalled forward by the station board”.

The station board was the final one encountered, and the only one with a working light or moving parts. It consisted of a 4′ square white board mounted on a framework and arranged to pivot about a vertical axis, and with a 1’6″ square trapdoor in the middle. To permit a train to enter the station, the stationmaster or porter-in-charge would first set the points correctly, then using the key obtained he would unlock the station board, swing it to face the approaching train, and open the trapdoor which revealed a solid green square with a green lens at the centre (lit by night). Seeing the green square or light was the driver’s authority to pass the Station Limit Board and enter the station. There was no equivalent to a starter signal: possession of the staff (once the person in charge had set the points and given it to him) was a driver’s sole authority to depart. Interestingly, the design of the system assumed that all staff/block/crossing posts would be manned, fair enough in a time when freight traffic seemed to last longer than passenger and demanded strong backs for unloading and experienced brains to keep the books. It’s also worth noting that a crossing place could only show a green in one direction at once, so preventing two simultaneous arrivals. It is not widely known that this actually duplicates both rulebook requirements and interlocking standards for signalled crossing places- in the absence of trap points and sidings, only one home signal should (or could) be cleared at once.

Level crossings were slightly different. It was assumed that parliamentary (as opposed to light) railways would have to keep manned crossings in place, so the only possible saving to be had was the elimination of the lampman. Gate distant and stop signals were replaced with 4′ square boards, which pivoted about a horizontal axis to be face-on for “on” and lie flat and invisible for “off”. These were white with a diamond shaped design on the face; Gate Caution Boards had a black and yellow quartered face with the word GATE picked out horizontally in reflectors while Gate Stop Boards had a plain red diamond and the reflectors spelt STOP vertically. In one case the stop boards were not in a separate frame but fixed to the gates themselves, and thus only visible when the gates were closed to rail. More prototype information can be found at here and here.

For modelling purposes, the proper way would have been to cut the boards out of ply, paint them and apply “bling” crafting crystals with adhesive (and we do have the bits to do that, and might yet one day) but right now a quick fix was needed. The various boards were drawn full model size in CAD, copy-pasted till we had the total number required (3 station limit boards, 5 location marker boards, 6 section limit boards, 6 Gate Stop and 7 Gate Caution), printed, laminated, cut out and stuck to kebab sticks and stabbed into the ground. They were only intended for the day, but 6 weeks later are mostly still there. The printer ink will doubtless fade before too long, but it doesn’t matter as they were quick to make and install and just as quick and easy to replace.

Pick a card: a shunting game for the garden railway

At the 2013 “Longest day” steamup some of our visitors were taken with the operational possibilities of the line, and wanted to actually, you know, operate the railway. At that stage I had a few pipe-dreams and half sketched out ideas for operating schemes, but needed to come up with something right now, that would be quick to produce, simple and easy to understand but challenging enough to be interesting, and fun. As it was a free-for-all steamup full-on timetable and working to rulebook was out, so I decided to concentrate on shunting operations and let the trains run freely once made up. It seemed to work, and kept the keen one amused for quite some time. Here is the recipe:

Ingredients: An assortment of wagons, some small self-adhesive labels, a pack of cards and some dice.

Preparation: Count the total number of wagons available (home and visitors’) for the shunting game, and count out that number of cards from the pack. Write on the labels, one to correspond to each card eg 7♣ for seven of spades, J♦ for Jack of diamonds. It doesn’t have to be pretty, merely readable. I used black and red pens to help identify the suits. Apply the labels to the wagons (choose easy-peel-off labels if you’re worried about delicate paintwork). Put the wagons out in your various loops and sidings, and leave the corresponding card in a stack at the appropriate station. We had one stack at each terminus, not using the intermediate stations so as not to block the running line for other visiting steamers who weren’t playing the game.

Play: Steam a loco. While pressure is building, roll the dice (how many dice depends on the number of wagons available and the preferred maximum length of train: For example 3 dice will yield and average train length of 10.5 wagons with a minimum of 3 and a maximum of 18). Shuffle the pile of cards for that station and draw a number equal to the result of the die roll: eg Roll, 3, 2 and 3 for 8 so draw 8 cards. The challenge then is to find the wagons represented by the cards drawn, and marshal them into a train in the order drawn (representing the fact that pickup goods trains weren’t built up any old how, but assembled into the proper order for maximum convenience shunting, attaching and detaching en route), not forgetting the brake van at the rear. Once the train is assembled, take the cards representing the train with you and head out onto the main line for a run (as long as you like, we’re not being strict here) before arriving at the other terminus. Upon arrival, add your cards to the bottom of the pile already present, and begin again with a fresh die roll for the return journey. Alternatively you could shuffle the cards, but adding them to the bottom of the pile is more realistic because it took time to unload wagons and one freshly arrived is unlikely to be ready to go back straight away (unless it can be unloaded very quickly, like a hopper or a cattle truck).

In practice it worked quite well, with enough work for three or even four engines (two working goods trains, and one shunting at each end while the train engines were refreshed and re-steamed). Whilst we didn’t use the intermediate stations and sidings, they could be added into the game with some simple rules changes (eg 1st wagon dropped at 1st station, either every time or maybe flip a coin and drop a wagon if you get heads), and 1 terminus off the circuit would be sufficient (we just used two because I have two). Have a go, modify to suit yourself, and if you come up with an improvement feel free to share it with us!

Winter 2013/14 to-do list

In previous years the local area group had a tradition of “The List”. This was solemnly passed around at the last steamup of the season, and all present would list just one of their many “Round Tuit” tasks awaiting completion, with the understanding that it would be done before the first steamup of the following season. It was just a bit of fun with no adverse consequences for failure (apart from a little gently mickey-taking) but sometimes provided the extra burst of energy needed to finish something off. With no club list in the offing this year, I thought I’d take time out to produce a list of my own, showing everything that needs to get done on the railway. No deadline, no “this one by spring”, no promises; just a warts-and-all glimpse behind the scenes of the average garden railway. Most of these are unfinished jobs, but some are unstarted-but-on-the-wannado-list.

Historical “research”
Complete fictional history for website. Complete train-graph timetables and use to work out fictional fleet, then use this information to create plausible numbers for locos and stock.
From traingraph, create timetable for Horncastle branch for use on “Operating Days” and try it out (solo & with wifey assistance) to test feasibility.
Prepare car-cards and way-bills for proper wagonload freight ops for “Operating Days”, and road-test (note that this requires all wagons to be individually numbered, with the option of removable loads for opens too)

Plan, advertise and actually HOLD an “Operating Day”

Enough there to keep me busy for a few years, if I retire tomorrow….. Would be nice to get some of them done though, particularly those relating to Operating Days, in which I plan to use the model to simulate a real narrow gauge branch rather than meander gently round in circles- fun though that is.

End of the 2013 season

It was the best of years, it was the worst of years (Shakespearish). On the plus side, the fleet is at its biggest and best ever. In January, for the first time in 20yrs a brand new just-for-us steam loco arrived to be unwrapped, admired and introduced to service- “Trisantonia” of the RH Atlantic class. In April a nice day out turned into a great day out when we were surprised to learn at the Roundhouse open day that our second new machine “Tennyson” (Taliesin class) was ready, and if we could hang on for 5 minutes while they found a box it could come home with us. Could we? What do you think. Finally after nearly a year of epic brain-bashing the Wizard of Wigfa announced in August that our Lyn was finally fit to travel- and with a couple of last minute tweaks she was. Lyn has been on the books since 2007 but with indifferent-to-nonexistent performance (not helped by a couple of boobs of my own) she’s never really been part of the fleet, more an expensive an frustrating ornament. Not now, though. Runs like a dream.

This insane and un-repeatable level of indulgence isn’t really our style, but it was a now-or-never thing. Taliesin and Atlantic had been on my ‘want’ list ever since they came out, and when it was announced last summer that they were to be discontinued it was decision time. Even then, it would not have been possible without Mr Back2Bay6 and his interest-free-credit scheme, a nice fat deposit and a year to pay off the rest made it do-able, so at the 2012 Llanfair show we signed on the line and settled back to wait for the postman’s knock. Lyn was delivered to Abbeybach at the same time, but a quick re-time and replacement of pony-truck pivots turned into a can-of-worms job, complete with long pauses for new bits to take the slow boat from China. The speed was not helped by my late decision to go for r/c, but having seen what a lively runner she was on test, and remembering how inaccessible the cab is I think it was the right choice.

On the down-side, for the third year running uncertainty over my work-schedule meant we missed the deadline for submitting “available” days to the local area group organiser, so we had to take pot-luck on steamup days. In the previous two years this meant we didn’t get to run every month and some days weren’t particularly convenient. This year we also had a change of organiser, who rather than send out an amended calendar every time there was a change sent out an email to all concerned. This is fair enough, and saves a lot of work BUT it meant that instead of being “on the calendar” we were lost in people’s inboxes and I think attendance suffered. Hopefully work should be more stable next year so we should get our “available” days sent off in plenty of time to get our fair share of dates properly displayed.

Apart from hit-and-miss attendances, it’s been a very poor year for visiting other railways. Work has been absolutely bananas this year. The continuing story of the joint-line upgrade has given us a non-stop year of last-minute crises, with the project blithely asking for impossible levels of extra shifts for engineering work even as our manpower levels shrink as people take jobs elsewhere while they can. It’s been impossible to plan more than a day ahead for any but the biggest personal events, and life has turned into work-sleep-work-sleep-work-runaway! Wifey is pretty good at spotting when I’m at the end of my string and in need of some playtime, and now we have the caravan a break is quick, cheap and easy to organise. The only downside to going away every long weekend is that there’s never any time at home to get things done, either chores or fun things. The project is also running late, originally down to be complete next March it’s now shaping up to continue until the end of August so that may be another summer up the Swanee.

So 2013 in summary, epic year for shiny new toys but unfortunately also an epic year of underachievement. No real progress has been made on anything, which effectively means backward progress as nature continues to take its toll on any model railway in the great outdoors.
