What switch should be used with the Walthers DD Commuter Cars? I'm planning to redo my curves and switches to handle these cars and better handle the regular streamliners.
If you mean what # to use, I would use the highest # you can for the space you have. The rest of the layout should also have the largest radius curves you can squeeze in. Jerry
IMO no smaller than a number 6 ;)
From the Walther's site
QuotePLEASE NOTE: As these cars are the correct prototype length and feature full underbody detail to match the prototypes, a minimum 26" radius is recommended for operation.
So there you have it...they recommend a 26" radius and that would translate to maybe a little higher than a #6 turnout, to be safe. But you can probably get by with 24" radius and #6 turnouts if you really needed to due to a lack of space.
I was thinking of using #6 switches anyway. I think a 22" curve will work with long-shank couplers on the cars. It's really the DDs that I'm replacing switches and curves for.
