HO DD40X

[quark51]

Hello, what is the best track radius for the DD40X and will this run on a analog layout? Bachmann should make them without DCC also. On my layout the radius is 22 degree.

It wil run on DC just fine. It will take 22" curves, although there is some serious overhang.

Hello, what is the best track radius for the DD40X

The "best" minimum radius is around 60 inches.  Fortunately for many, the model will go as tight as 22 inches.
