When I changed the roundhouse and turntable over to the EBT from the S standard guage, I figured that I would have to alter the scratbuilt roundhouse to look a bit more like the EBT prototype. 

Here's the way it originally looked.

Here are some shots after the alterations. There are 4 stalls on the model while the prototype has 8. The main changes were to the roof and the doors.

Here's the new model after some weathering was added for smoke over the doors.
