Union Pacific Grey Hound Challenger comes home

One of my favorite locomotives and paint scheme is the Union Pacific Grey Hound two tone grey on heavyweight passenger cars.  I have had this loco that matches the cars for awhile and it suddenly ceased up.  I am past the age of disassembling a N scale steam loco so it went to the manufacturer - Athearn.  Came back like new and lubricated.  Money well spent.
  
I have not run the train for quit a while but now it looks right.  The cars are by MicroTrain and were  brought to the market over many months - one at a time.  Now I have a consist of 14.  That is enough and a load for the loco.
