I have a Bachmann Car shops building. It is a 3 track structure with grooves in the floor. How do I attatch rails to the floor? or should I just bring rails to the door and not be able to run a switcher through the building?
The Walther's Roundhouses are similar. I just used CA glue to attach them to the floor. It was Atlas code 83 flex with the ties cut off. Then the rails right into the grooves. My engines run beautifully into the roundhouse.
Here's a video of the engine going into the stall... video
