I bought the 'O' tin-plate Christmas set last year and quickly found out that it can't handle 27" curves. lesson learned so OK.
BUT.... I set up a little layout last night using MTH's RealTrax and the tender's rear truck keeps derailing going around curves. I don't know the diameter size that RealTrax makes. I looked at the catalogue for the recommended minimum curve but it doesn't say anything.\
Does anyone know what the minimum requirement is for this engine???? The engine is listed as a the 261E locomotive in the set numbered 11-5509-1. This is frustrating to me that it can't run on the track that was included with the set.
as always, thanks - walt
