Posted by Jace on Wed Jul 8 14:25:19 2015, in response to LIRR M-9 Screw Up, posted by R2Chinatown on Tue Jul 7 21:47:08 2015. Uh, not quite. The M9 PTC system is two parts: ATC and ACSES. The 8 cubic foot space provision is for the ACSES equipment only. The ATC portion of the equipment is integrated into the car design. The latest and greatest ACSES equipment turns out to take up more space than originally thought (17 cubic feet), that's the rub. There is no FRA requirement saying that so many square or cubic feet are needed, they only specify performance.I wouldn't call this a design deficiency or a screw up. They didn't know what the ACSES equipment would look like, came up with an estimate likely based on earlier versions of the equipment but came up short. Consider that the original provision would have been met with a locker 2'x 2'x 2'. Now it requires one 2'x 2'x 4.25', not a huge difference but a challenge finding space in an already cramped car as the LIRR noted at the meeting. I would imagine there'd be plenty of complaints if instead they overestimated the space and ended up knocking out a seat or two thanks to a giant, largely empty ACSES locker. Newsday is simply playing this up to make the LIRR look bad (now there's a surprise), no complaints from them about the delays and costs associated with beefing up the rear end collision posts, also discussed in last month's committee meeting. |
