Anyone used these to power a loco?

Those are a near perfect replacement for old Tyco shells the way they are shaped. I had a friend in High School that used a pair of the old PDT's to power a Western Pacific GP-20 (high hood) that he kitbashed (remember this was the 1980's) from a Tyco GP20 shell and lots of detail parts. He used these so he could model open hood doors and made a miniature EMD 567 block to show through the open hood doors, thus necessecitating the need to have the shell totally open. It ran *ok*, but was not a really good puller. And forget about MU'ing them to another unit (he had Athearn and Atlas engines then). So, his WP GP20 toiled around by itself switching the yard at the club. Did ok like I said, but its slow speed characteristics were really poor. Not to say they haven't improved it since then, this looks like a PDTv2.0. I think though for the small motor, lack of flywheel and desire for slow speed operation, I'd pass on a road unit or switcher application. Now an interurban or trolley I'd use it in a heartbeat.
