What year was this loco made? What kind of motors/drivetrain does it have?!
Here's a bit of history. The Challenger data is as of 2017. Not sure when Jim Waterman bought the tooling, but he has only made 3 so far. Jim is using MTH Build A Loco motors. Mine was made this year.
I bought the Harmon tooling (and some parts) from Bob Thon in 2018, so about a year into build. So far, 3 Challengers and one Pacific delivered, and one Hudson and another Challenger in work. Plus about 35 Harmon cars built in PRR, Southern, B&O and Milwaukee (bought 50 sets of castings, most are accounted for, but I can order more). I have parts for another 6 Harmon engine. Getting harder to get new parts - a lot of Lionel 400E parts used (BAL motors, lead truck, valve gear, steam cylinders for example).
