When doing my permanently sidelined freight car truck article I had several ocations to talk with the Atlas staff about their Accumate trucks. They stated they will be moving over to short shank couplers as they have time (or tooling breaks). I have been pushing hard for their underslung 100T trucks becasue of the short shank and low profile of the coupler box. This truck fits a lot of intermodal equipment and gondolas other trucks with couplers cant.
You will nnotice the new 100T truck on their Thrall gondola and 20K GATX tanks. These are made by a new company (not Kader/SDK). The detail isn't quite as good but they do couple better. There are actually 4 100T Accumate trucks by Atlas 1. the ASF truck with explosive couplers, 2. the Barber S2 with not so explosive couplers. 3. the sweet Barber S2 with underslung, short shank couplers and 4. the newer short shank truck.
