Modeling State Line Interchange Yard & Rising Junction part 8 - Structures

Several signature structures are needed to complete the State Line interchange yard and Rising Junction dioramas. Modeling efforts for the layout will now focus on these structures until completed.

As a reference, part 3 of this series describes layout location of the roundhouse and associated turntable. Parts 4 & 5 are about the modeling of the now completed turntable. 

Modeling the 1918 roundhouse

The foundation 

Fortunately for modeling, there are a set of original New Haven Railroad State Line roundhouse plans available for purchase from the University of Connecticut Library archives at the Storrs CT. campus.

Printing the ground floor plan from the set in HO scale has been very helpful in transferring the dimensions of the foundation in relation to the turntable and locating the structure onto the layout surface, see below.

After marking the four corners of the structure onto the layout surface, the print was trimmed to just the foundation footprint. 

Next, the inspection pits were cut out of the print and the locations were transfered to the layout surface and cut in.

A piece of 1/8" masonite will be used as the base plate to build the model on.

The same print is used to mark and cut out the masonite.

The original plans indicate that the roundhouse floor was concrete covered with asphalt.

Next, to model the floor surfce the masonite will be covered with .040" styrene.
