Fellas...new here just looking for some info. What are the measurements between the rails of a G scale track? I'm goofing around with an old Playskool Express battery operated plastic train for my nephew's little guy. The set has too many curves and very few straight tracks. Would this thing run on any other type of model rails? Thanks, Paul Respond by email would ya? I'm not sure how to get back to this forum. [email protected]
