Wow!  That's huge - would there be certain layouts that would be too tight to run that on, Todd?

Seller mentions doing a usual locomotive maintenance - what would that be?  I always thought electric trains were just put 'em on the track and go...

On a side note, I recently bought this book, which has history of the Big Boy and documents the restoration of No. 4014.  Haven't read it yet, but I'm sure it will be riveting...

Apparently this locomotive will work on a 15" radius but I think it'd look kind of silly. As for maintenance you'd want to make sure the factory lube isn't hardened and all the axle are free moving. I bought a non running locomotive from the 80's that was still in the box a few years ago and the axles were seized to the chassis. Once I freed them up and cleaned everything the locomotive ran great.
BTW -I'm the seller. I need to downsize a few things and the proceeds are going towards getting my truck up to snuff.

I really want to get something set up but like you Mark I can't seem to find the time. If I ever do it will be a shelf layout going around a room.
