Hi Folks, Since I have the new steam engine and hope to get a BLI diesel also+ I have lots of "stuff" to run I have to incorporate a main line. I prefer no duck under, so if I take the closet out I come up with this plan with two 4 ft turnaround and a yard leading to the door. I also have lots of room for traction. What ya think? Chris. Room size is 16ft -8ft -8ft angle to door -10ft this HO .
