My layout plan is based on the eastern portion of the TP&W. Prior to the formation of Conrail in 1976, the eastern half of the TP&W connected East Peoria, IL with the hamlet of Effner, located on the Illinois-Indiana state line. (The main settlement of Effner is on the Illinois side, but the TP&W's depot was located just across the line in Indiana.) Conrail didn't want the former Pennsylvania RR branch from Effner to Logansport, IN, so the TP&W was forced to buy it in 1976 in order to maintain an eastern connection. In the space I have available (see previous post), I think I only have room to model 2 scenes with some connecting track between them. For those 2 scenes, I have chosen to model Effner and El Paso, IL. Including Effner gives me a place to interchange entire trains with the Penn Central. Of the many small towns along the eastern TP&W, I chose El Paso because it had a diamond and interchange with another railroad (the Illinois Central Gulf's former IC Charter Line), a cool joint depot at the diamond, and a downtown strip of storefronts facing the TP&W main that seems tailor-made for a layout. I'm not attempting to model either location entirely true to the prototype - though I anticipate scratchbuilding the El Paso depot - but rather capture the flavor of each place.
I used AnyRail software to design the layout using Atlas Code 83 track. Here's my current plan:
Phase I of the layout is a 4 foot by 6 foot table that includes the El Paso town scene and a loop for continuous running. The loop was a must for me because I want the ability to just run a train without intervention, both for my own entertainment and for the benefit of my young children. Six feet is as far as Phase 1 can stick out into the room without causing access issues to other parts of the room. I have a number of storefront buildings from my previous layout that I'm planning to reuse in the El Paso scene. There are only two spurs in the loop: one is a team track adjacent to the depot and the other will host a feed mill and perhaps a second industry (hence the question mark on the plan).
Phase 2 is a 2 foot by 4 foot section added to Phase 1. This additional space allows me to complete the interchange track, add an industry (a Walthers propane dealer kit reused from my previous layout), and add a track that can initially be used for staging but will eventually be a passing siding. I've thought about just building Phases 1 and 2 at the same time, but I want to stay focused on getting the loop up and running first.
Phase 3 adds an L-shaped extension to Phase 2 that includes the Effner scene. Effner includes a 3-track interchange yard, a grain elevator, and a wye for turning locomotives. I think the relatively short trains that I will be running on this layout would look weird with more than 1 locomotive, hence the need for the wye to turn power at the end of the line. The prototype Effner wye no longer exists today but was still there in the 1970s. In order to maximize the length of the tracks in the interchange yard, I'm planning to have the tail track extend through a hole in the wall. The notch in the shelf at the end of the layout is necessary to clear one of the access doors to the storage area under the eaves (see my previous post about the layout space.)
Once the full layout is built, I envision originating trains at Effner and then running to El Paso and back. The interchange track at El Paso forms a reverse loop that facilitates this "out-and-back" layout concept.
