Remind me: why won’t MTA install platform screen doors?

Recommended Posts

Because.....

 

 

They'd rather continue to burn thru billions of dollars under Park Avenue.

My Guess as to why the (MTA) won't install Platform Screen doors:

1. Train Lengths are different. (This is specific to the B Division only where you have 60' and 75' trains)

2. It'd be hard to maintain on a regular basis, and certain parts of the Subway (if not the entire system) will no longer be able to run 24/7 (considering (MTA);'s current maintenance habits. Correct me if I'm wrong)

Its disappointing that this is how people end up losing their lives. Whether it'd be suicide or some other case. What happened to using common sense?

also , knowing mta , there’ll be multiple cases of where the platform doors get stuck and no one will be able to enter or exit

Well the simplest answer is that the stations weren't designed for it and retrofitting screen doors would be difficult if not impossible, in addition to train doors on some fleets not lining up with others (the R211s having wider doors will practically lock us into this situation for another 40 years.)

Yeah. Imagine installing PSDs at Wall St on the (2)(3), or Myrtle/Broadway. There'd be no platform left!

Hell, some places that do have them (and actually strive to maintain them) sometimes run into critical faults.

Outside of anything money related, fear of success....

Then again, it's impossible to try to quell the rampant stupidity of the general public, so I guess I'll have to take that back....

It can't really succeed without design consistency (we're not there just yet).

People act like when a project is discussed it must be implemented across the entire system. They can easily install platform doors along the (7) and (L) lines for a start. Then gradually learn how to eventually implement it across the entire system. Technology will eventually be advanced to the point where it could definitely work in most parts of the system. 

They can implement platform doors across the entire LIRR system if they wanted tobut clearly they aren't ready for that type of modernization especially with the management and type of operation they have now. It's possible though don't get me wrong.

I somewhat agree with this a little...They did choose the (7) and (L)  for CBTC because of non trackage sharing......Now they gradually spending that across the system for better service...

That's nice.

Unfortunately, the issue is a physical one. The IRT's SMEEs have doorways that are directly across from each other. While the NTTs' A cars have this feature, the B/C cars don't. This is particularly problematic for the (7), as the combination of 5-car and 6-car sets means that any installation will require the 5-car set to be on one end and the 6-car set to be on the other, or else several cars will fail to align. (While this is already practiced, door installation will mean that trains in the reverse configuration -- which is no less safe without the doors -- will forever be barred from operating in revenue service.)

The bigger issue, however, exists outside of the IRT, and that's not just a figure of speech. So long as we have those 75-footers, the options for installation will be limited, and that problem will persist if new 75-footers are ordered (for whatever reason).

They can use screen doors that open vertically.

Not only does that concept have virtually no prevalence (it certainly won't be taking the world by storm anytime soon), but it only addresses the IRT's door placement issue (while opening another one concerning stations with pronounced curves). It does absolutely nothing to address the discrepancies the 75-footers bring.

75ft cars won't be around forever, which is why I'm saying eventually it can be installed across all lines at various stations.

Also, your note about the (7) with the car configurations. Who cars if the 5 car sets gotta be on the western part of the train and the 6 car sets on the eastern? That's what they run now, that's how the stop markers are positioned, and LIRR has its trains to face only one direction as well so that's an invalid reason.

I don't know if you were paying attention, but I specifically brought up the idea that the MTA could be boneheaded enough to order more of them (not in those exact words, but the idea is still there).

  1. I already acknowledged that.
  2. That's implied, though the MTA can have the boards installed for more than one configuration (look at where shorter trains run with full-length ones).
  3. Great, all LIRR trains have the cars face a specific direction. That's not a good comparison, as all EMUs run as married pairs, whereas diesel trains have more limited consistency than electric ones.
