I recently purchased a 3rd Rail PRR E-7 in the second run. Beautiful engine to be sure. However, I am having some operating difficulties, particularly in the curves (track is GarGraves), which are all 0-72 or wider, as the engine (primarily the rear truck) tends to derail. I suspect the flanged center wheels of the trucks are the cause. Has anyone experienced this problem? Does anyone have a suggestion for addressing it? Thanks.

Along with the flanges maybe check the chasis for something limiting the truck movement also the pickup roller may not be centered and one other possibilty may be the wiring around the motor may be causing a turning restriction.........Paul
I have the E7 and 072 curves and have experienced no derailments.
I did have a center roller which was defective, but functional, however I got a replacement for it yesterday (Thanks again Christopher!). I wouldn't think the tapered center roller would cause a derailment, but I'd still check them all as well as the rubber tires.
I also don't run mine at full-bore. With the DCS handheld remote, I generally run it no greater than 50-60 speed steps, using 128 SPD mode (in TMCC mode the DCS handheld reads Speed Steps NOT SMPH).
