DOT-117

Postby Richard-B » Fri May 01, 2015 10:12 pm

The US DOT announced their "Enhanced Tank Car Standards and Operational Controls for High-Hazard Flammable Trains" today...
New tank cars constructed after October 1, 2015 must meet DOT-117... and older cars must be retrofitted according to a schedule.

DOT-117 has a full-height 1/2in head shield, an 11-gauge jacket, and a 9/16in shell...
Expect to see un-modified DOT-111s fade out of HHFT service.

Other than an artwork change to reflect the revised standards, I don't think there'll be any visual differences from the side of the track.

I don't disagree...
The most obvious spotting points may be the top equipment (dome) and bottom outlet valve configurations, as well as the increase in car size to 286 GRL (lbs.) from the previous 263k GRL.

What I think it also means... is that new and retrofitted DOT-117 cars will take over the High-Hazard routes, pushing some recent but un-retrofitted DOT-111 cars into general service, and accelerating the phase-out of older/smaller GRL cars.

Yea, but most of the Procor cars I've seen traveling down the old Spokane International line the last five or six years already appeared to be 286K from their trucks, etc. The dome externals look the same to me. I think this is more likely to affect the cars coming out of the Dakota's heading east. If the 100 ton trucks can get made, this would be an easy car to make and sell in RTR and would cover alot of years and models with just different artwork. Same trucks also cover both recent three bay covered hoppers, add in Midwest TT's Berwick boxcar restenciled for private ownership and you've got something prototypically correct for the GP-38-2 to haul around town.
