So a train travelling 45 miles an hour can be stopped in 375 feet using emergency brakes? That is not surprising, as i have been on trains that coast into stations at 45 miles an hour for a bit before grabbing any air. And the motorman still releases and lets it coast a bit before doing the final grab, coming to a stop. This is all without using full service for long, and definately without using emergency brakes. By the way, Brightliners are the ones which can do this, they definately fly into 42nd street faster than a r44.That is a shame that the STEELS, with their one powered axle per truck, could pull a canarsie faster than the New Techs. Similar in the way an Arnine with one powered truck started to overtake a hippo from 34th-42nd. I will not argue that the Standards outperformed the new techs, because i don't know how they performed, or how fast they were, but i assume the new techs have better low end acceleration than Standards due to more motors. This means it is the signalling system which is preventing the New Techs from gaining respect. Timers slow down the line, take them away from where they don't need them(straight aways, tubes), then the New techs will be able to pull off a 35 minute run time. Forget about comparing that to the Bluebirds or Multis though. Although those trains had their issues, they were FAST, so they could probably do the canarsie in less than 30 minutes, no doubt. |
