there are no roundhouses to fit the bachmann n scale ez track dcc turntable. It has a 24-25 degree angle on the diverging tracks. Could I alter a heljan b 643 6 stall roundhouse to fit? Maybe get 3 stalls out of it after alterations?
It looks like the tracks would have to converge after leaving the tt and be directed to line up with a roundhouse of your choice. Most roundhouse kits are based on 10 or 15 degree track spacing. This is the problem with turntables that have fixed degree positons. If you already own the Bachmann turntable then you don't have too many choices. You could use some engine house kits and just run the tt tracks to them as opposed to using a roundhouse.
