Thank you.  I like it myself.  Will be working on the Pennsy tomorrow morning.  I'm guessing that I put too many fiber washers on the driver axles to prevent shorts.  The driver wheels have no side-to-side wiggle room.  Will be pulling the washers one-by-one to see if that helps.

Regards,

Jonathan

Solved it!!

Once again, it's the brackets that hold the brakes on the pony trucks, running under the steam chest... They lift the front of the loco, ever so slightly.  The lift is just enough to make the driver wheels lift and roll over the rail heads, on a curve.  Fortunately I don't have to disassemble the engine.  I can resume filing away at the cylinders with the trucks removed.

Thought I was sooooo clever by adding brakes to the lead trucks.  That'll teach me.

Sheepishly,

Jonathan
