I have purchased a large job-lot of unbuilt Athearn Blue Box 50ft boxcars. I’m looking to replace the wheels with better code 70 compatible types (probably Proto 2000 ones), but which size should I be buying - 33" or 36" wheels?
Can anyone give me a pointer on what the best brand/size of replacement wheels would be? Also, any pointers on ways to lower these cars to a more prototypical ride height?
Rule of thumb. Your typical steam era 1960s to 1970s boxcar, gondola, flat car, reefer, stock car, caboose, tank car etc., etc., all used 33 inch wheels. Passenger cars use 36 inch wheels.
As others have said, you’ll want 33" wheels for your boxcar. AND…depending on your era, you have a choice of “ribbed” or “flat-back” wheels. Unless you’re modeling cars from the 30s, flat-back wheels is what you want.
