Planning for enjoyable operations on smaller layouts

While much has been written about the elements of a successful operating session for a large crew (usually on a large layout), many layout owners have the opposite situation. Is there a way to make operating sessions fun on a smaller layout, with one or at most a couple of operators?
Absolutely! I think the ability to have fun on a small layout depends on four straightforward elements: some diversity in the roles the operator takes on; some variety within each role; the unpredictability that comes from incorporating "external" requirements; and a fair degree of challenge.
Diversity in roles
This might be difficult to imagine in the context of a single operator on a smaller layout, but offering different types of roles can be done even in fairly tight quarters. One of the keys, I think, is providing a different sort of challenge in each role. By this I don't mean "switch the brown boxcars on odd-numbered dates and the rest on even-numbered dates", but rather a different type of challenge altogether.
"... diversity ... variety ... unpredictability ... fair challenge ..."
One of the ways I like to provide these different roles in a layout design is by including both a classification yard as well as the more traditional switching challenge of pulling and spotting cars from sidings. In my personal experience, these two roles feel quite different, perhaps because they exercise two different kinds of thinking. Game designers divide puzzles into various classifications, and among these are "Ordering" challenges and "Sequence" challenges.
Sorting out cars within a classification yard is an "ordering challenge". There might be an optimal solution in terms of minimum number of moves, but any number of different starting approaches will yield the final result.
"classification yard and  ...  industry switching"

Spotting cars into sidings falls into the "sequence" category, particularly if room is tight and a mix of facing- and trailing-point spots are involved. The classic Timesaver puzzle is very much a sequence problem … pulling or spotting cars in the "wrong" sequence of steps greatly increases the time it takes to complete the puzzle. (See the sidebar at right for more on the Timesaver).
The industry yard that supports a (relatively) large industry or an interchange yard near an industrial area are two quite-plausible themes for a small layout that will offer diversity in operating roles. The solo operator may work these jobs in turn at different sessions, or move back and forth between these roles as the fancy strikes.

What about the Timesaver?
The Timesaver switching puzzle has often been held up as an ideal small operating layout. While it is a devilishly clever puzzle, the Timesaver is not much like real railroading and for me, at least, the fun is gone long before the challenge is over. Others certainly disagree, but I think some of the other ideas described at left, when incorporated into even a small layout, will provide more long-term operating satisfaction.
Those who are interested in the Timesaver (and its British cousin, the Inglenook) might enjoy Adrian Wymann's Shunting Puzzles web pages and Neil Machin's virtual online Timesaver and Inglenook layouts.

This layout configuration need not take a lot of space. I recently designed a pair of T-Trak modules which provide a small classification yard and associated substantial industry tracks in roughly 8 square feet total of N scale layout. Another small layout combined shops switching and a small yard in about the same space.

Variety within a role

The most basic part of providing variety within the role is to use a somewhat randomizing method of car routing. Spotting the same car in the same place each session is a sure way to mind-numbing boredom. Some layout owners use dice rolls or other random elements to determine car movements. The traditional car card and waybill system can also provide this variety, especially if the waybills are removed from the car cards when all the cycles are complete and new waybills inserted. Having a larger roster of cars than can be accommodated on the layout at once also allows some increased variety through the swapping out of rolling stock. Utilizing sure spots (such as door numbers, loading and unloading spouts or pits, etc.) can also add to the variety.

In real-life, shifts have a large impact on the tasks crews face each day. The need to spot or pull cars at certain times, re-spotting cars as required, can add an interesting mental challenge to typical car-shuffling switch jobs.

Incorporating "external" requirements and events

Slightly more advanced and "railroady" variety can come from the inclusion of elements such as seasonality, customer requirements, etc. If cars are spotted in accordance with a customer's demands (perhaps defined by the turn of a situation card), unexpected and welcome challenge may be added to the solo operator's tasks. This can include different loads based on the time of year, different mixes of ingredients which must be delivered from cars in the yard caused by a change in demand for the customer's product, etc.

Additional elements can include specific rules regarding air brakes, breaking trains to avoid blocking grade crossings, and the impact of imagined weather or labor events. I include some of these elements when operating my small San Jose-inspired switching layout at right (also discussed in LDJ-29, Jan. 2004 and on-line here).

I currently operate the layout with three manual switchlists that represent different times of the year. For example, at some sessions more fresh fruit is loaded, at other times more canned products. I've incorporated a number of grade crossings, two railroads, and "sure spots" to maximize the operating challenge within the context of a railroading simulation. With that said, there is still sufficient  room to maneuver to keep the puzzle frustration to a minimum.

A fair and realistic degree of challenge

Enjoyment or tolerance of puzzle challenge is likely a matter of personal preference. Game and puzzle designers write of the player's perception of the puzzle designer's "fairness" as a primary contributor to fun. Providing sufficient run-arounds and a little "breathing room", for example, allows the solo operator to concentrate more on the challenges of modeling a railroad's operations than on the mental gymnastics necessary to solve a strictly-defined puzzle. The challenge should be in the context and theme of the railroad simulation, not a grafted-on "move-the-empty-slot" quiz.

At the same time, some degree of challenge makes a layout more engaging and interesting to operate. As with many areas of layout design and operations, this is one of striking the right balance. One recommendation would be to design small operating layouts with sufficient trackage arranged in a way to make switching moves straightforward. If this becomes boring, added challenge can be created through situation cards or declaring a turnout or two "out of service".

"... reasonable challenge ..."

If the layout is a little larger, but the crew is not

Many "lone wolf" operators have slightly larger layouts, from the "sacred sheet" 4X8 on up. With more space, the possible inclusion of staging yards and the like, it is a bit easier to create the variety and challenge that makes operations fun for the solo operator. Again, the key is to define operating tasks in such a way that there is real diversity in operator roles from session to session. This operating diversity can often be added to the layout after it's built through operating guides and tools.

In my own Port Terminal Railroad Association design (Model Railroad Planning 2002), three or more different operating roles are accommodated. One evening the solo operator might take on the role of the SP crew, working a few sidings and perhaps some interchange with the PTRA. Another night might find us operating the PTRA switch job from staging to the small yard at the top of the diagram. And yet another session might find us working the yard and the large Equity grain elevator sidings. Not bad for an N scale 4X8! And when a larger crew is available, these different logical roles make it easier to share the fun.

Ops can be fun for one

A focus on variety and prototypical operating situations, as opposed to pure puzzle challenge, can help make even a small layout fun to operate. If you'd like to discuss a layout design for a fun solo railroad or ways to add ops interest to your existing layout, please contact me.
