A Revised PoLA for a Reader



One of the readers of my book, "Waterfront Terminals and Operations" asked me if I could develop a modified plan of my PoLA layout to fit his space. He was currently modeling a plains railroad in HO scale but was unhappy with its design. In particular he felt he had tried to cram too much stuff in his layout. He liked the PoLA design for its operation potential and manageable scope. He also requested wide aisles to ease access. He has two rooms available for his layout with an assortment of doors and windows. The overall space is 31 by 15 feet with a few obstacles here and there.

Here is the plan that I developed for his space. It's an enlarged version of my own plan with longer sidings and a few extra industries. Initially his back room is reserved for staging, but the layout could easily be expanded in that space later with some of LA's shoreside industries.


This layout supports a lot of varied operation. There are industries for tank cars, auto racks, covered hoppers, box cars and a break bulk terminal that can accept just about any type of car including double stacks, gondolas, depressed center flats, steel cars, etc.

The long sidings add interest to the operation especially when combined with industry spot numbers. For example, switching the single siding at Vopak can be quite involved when cars have to be placed at specific spots.

Some of the sidings are quite long, in contradiction to normal model RR design practice where designers try to cram more, but smaller sidings into a design. I don't like that approach. First, most of the industries on a modern layout have long sidings to provide the rail transportation service they require. Otherwise, they probably use trucks. So designing a layout with longer sidings is prototypical.


Secondly, switching long cuts of cars on a layout feels more  prototypical than the usual one car out-one car in used on some layouts. It  requires good engineer - brakeman coordination. It also presents an imposing spectacle. Watching a string of 15 auto racks going in and out of WVL is really cool. See the video below for an example.



The same concept would apply when switching Pasha, where there are 4 parallel long sidings. This could almost quality as a model railroad yard. Switching this industry can be akin to working a yard with sorting and blocking. The operation can be made even more involved if some cars on the long sidings must remain, while other cars deeper in the siding must be pulled. I do that on my layout when I have more advanced operators to make the tasks more interesting.

    I also like the look of 6 cars on a 9 or 10 car siding

  2. Very nice Bernie. I bought your book, saw your plan for Philip H, and keep eyeing these terminal layout plans.
