Well guys the info i am getting from Bachmann is that none of there standard loco units have flywheels. only the Spectrum units have them. This is Ho scale.
and i checked on there website and none of the brake downs they have for there standard units show any flywheels. but all the Spectrum units have flywheeels.
Here is a link to there Standard gp38-2 with DCC it says but i dont see the decoder in the brake down.
