So the OO scale Class 43, AKA the HST or Inter-City 125, which had a top speed of 125mph in real life. I re-motored these with can motors.
As a pair (both are power cars), although Hornby produced them as a Power car and dummy.
Crawl speed was abysmal, even though both are fitted with Loksound5 decoders.
it could well be me, when I speed matched them, I didn't have this speedometer, so it was all done by trial and error.
My Bachmann Class 37-0, with a Bachmann non-sound (Zimo) decoder. This did quite well, it's about the same weight as the Athearn CP SD70. IRL, these had a top speed of 90mph
Crawl speed was impressive as well.
It did actually go slower, so slow that the speedometer wouldn't record it.
