Rapido CN 8-40 CM. MT couplers.  Bought this new from a friend.  It came with two axles with traction tires.  I don't like traction tires.  I contacted Rapido and they supplied two replacement metal wheeled geared axles.  So they have been replaced.  The originals are included along with a handful of spare traction tires that came with the loco.  I have put about 5 minutes on the unit.  Wheels show no wear.  Original box.  As is, which is like new.  This is a DC locomotive
