U30B and a Roundhouse Harriman coach

[MikeGTW]

Was looking thru some stuff and found this Athearn U30B dummy with the clip on plastic trucks looked at the bottom and why does it have the motor mounts in it Took off shell and there's the motor never been run by the look of it so the only trucks I had were a pair of Blomberg looks fine to me
The Harriman coach didn't have trucks or couplers so I put a pair of old Red Ball metal trucks and Kadees

SCL and others used Blomberg trucks from traded-in EMDs for some of their B trucked U-Boats, so it is an entirely plausible thing to do.
If you still have the AAR B dummy trucks, you may be able to swap the gears and wheelsets into them.

Nope they are the real cheap one piece plastic ones no way to change anything on them
