Posted by WillD on Fri Aug 28 21:18:12 2015, in response to Re: SI Railway - no new cars till 2020 - NY1 video, posted by Joe V on Fri Aug 28 06:38:10 2015. We can run 4 car subway trains OPTO, assuming battles can be overcome with FRA and then the UTU. So that takes care of your crew costs issues.Battles which would be easier to fight if they were to go to LRTs. That is a hardly noticeable improvement and won't cut costs. Yet you've used a 5 minute time savings as a justification of your 7 train to Secaucus scheme. So again you present another double standard. If it helps your case then those 5 minutes are vital. If you're arguing for maintaining the existing underperforming equipment (why?), it's suddenly "hardly noticeable". If you are going to have an LRV car with a subway car level floor, you will simply have an LRV car trying to be a subway car. ...which will still be lighter weight than whatever monster NYCT is going to procure as their next generation subway car. You can cherry pick to find a heavy rail vehicle lighter than an LRV, but NYCT isn't going to buy a WMATA Rohr car, and NJT didn't buy Buffalo LRVs (nor should SIRT be equipped with NJT LRVs). We can change the gear ratios on subway cars to be like WMATA or PATCO cars to speed them up their acceleration. No, you can't, because then you're simply giving up top end speed for acceleration. The only way you're going to get higher speed is to increase power or reduce weight, which means... It is also a function of power distribution, which SIR has not had adequate supply. That seems to me a perfect reason to go with LRVs. They'll accelerate faster with less weight and result in a smaller current draw on the power distribution equipment. Actually, going to two shorter LRV trains running a couple of minutes apart is a perfect way to reduce peak demand on the rectifiers. |
