There are no prototypically correct HO scale plastic IC steam locomotive models for the period from about 1936 when the rebuilding program started in Paducah until the end of steam on the IC in 1960.  There are some brass models available on the secondary market. 

I'm continuing to make progress on the two modules that will model the area around the IC Freight House and the industries around it.  The IC had a large freight house in Centralia, most likely much larger then necessary.  The freight house was 182' 2" by 40' 8" with a wooden freight platform at the south end that was 274 feet long.  The platform was actually two separate platforms.
