I just got my latest passenger set running on the layout, here's the tail end of it. It's a Lionel Classics Railchief set!
Had to spend some time lubricating all the cars. These Railchiefs are heavier than they look, the roofs and frames are all solid castings. The gentleman I purchased this from claimed that it ran better than his rare original one since the reproductions have nice pickup rollers instead of sliding contacts.
Here's a video of the Railchief running with my MTH American Legacy 700e Hudson!
