Weighting along with the Gold Line metal wheel trucks makes this train run EXTREMELY SMOOTH! The locomotives have a few hours of runtime on them but the cars have only been removed and ran for about an hour at a Club Open house. All have been in storage for quite a while now and the locomotives should have a thorough wheel cleaning. I work for BNSF and run these coal trains a couple times a week out to the Ports in WA so I ran it prototypically as 2x1 (DP'd) with a sound unit on the front and rear with rear DP running in reverse to replicate the trains I'm use to running.This box is large (18x14x9) and with packaging weighs over 18lbs.
