American Brick Locomotive Works
Big Boy got an upgrade.
With 2 XL motors, I thought I might as well make sure they can get all the Power they can get. Other minor upgrades and adjustments: better traction tyres, rod and valve gear adjustments, lead truck lengthened by half a stud for better R40 negotiation. Tender pushed back a half stud for better R40 negotiation as well. She runs great and handles R40 curves just fine.
