TRF18
You are doing nearly exactly what I have planned. I am doing a RCS 3 way on my bridge to a 3 track ~38 inch barge.
An interesting point, given concerns about space, the rail barge is my approach to dealing with my space issues. Rather than doing a fiddle yard, cassette or sector plate, like our European and UK brothers, I decide to make it a scenic feature. It will provide a place for me to roll-on and roll-off rolling stock, creating an obvious connection to the outside world, provide me a "permanent" programming track and with the addition of some rollers a stationary test track.
