N scale flat car for truly heavy loads; based on the GEX 80000. This car is huge, just like the real thing, you will get to spend plenty of time shuffling it around your layout trying to avoid problems with overhang on curves. You must either weight the car or build a load with some heft to keep it on the rails. There is a generator included, it will work if you fill it with BBs. Uses 8 (!) Intermountain trucks. Updated the lower bolsters to provide a bit easier railing and better side to side stability,Print each large piece laying on its side with support. You will get to spend some quality time with your hobby knife when complete. If you use mesh mixer, the car body prints nicely at an angle. You need: 1 upper 2 mid 4 lower 8 short pins - universal or intermountain (print some extra) 6 long pins
