I'm wondering which is the longest offered under a model, in order to use for scratchbuilding.
I measure the old Kato/Atlas ones at 17.8mm. As used under their RS3. Unsure if the (Kato sourced) U25B or RS1 have the same truck but I expect so.
Told others are longer. Unsure about relatively recent entries such as the LifeLike/ Walthers RS2, Bachmann RS3 or H16-44.
The measurement is from axle point to axle axle point on the the truck.
In real life, these trucks varied from 9'4" to 9'6" (some FM) to 9'10" if they had Westinghouse motors like many Baldwins.
Cheers, Ben
