Usually in the early morning, the Erie yard job at JA Tower can be found switching the the GE Compressor Plant on my Central New York and New England (CNY&NE) Railroad on the East end of my Northfork Yard.  The structure is only 5 inches deep and has 2 staging tracks running inside of it.  They run the length of the yard holding trains for a connecting branchline. It was built using a custom blend of City Classic modular warehouse components with lots of roof details.
