Re: [SergentEng] Re: Coupler bining in draft gear boxes
Autoracks definitely have a longer shank than covered hoppers or tank cars, but it isn't as apparent as on centerbeams. In the same way that the shank moves in and out of the draft gear on a centerbeam as part of the cushioning mechanism, so the same occurs on an autorack. You can see the action as the cars change from draft to buff or vice versa (you can certainly feel it), but generally they operate in a state of equilibrium.
I don't think the extra length is as apparent as on a centerbeam, but there's something there. I have several autoracks with the standard Sergent E coupler installed, but they always look like they're in buff to me. I intend to buy some +0.1" shank couplers when they are available again to see how they look. I tried the +0.13" shanks and they are too much, but they look okay on bulkhead flats.
