m7zanr160s Posted February 17, 2010 Share #1 Posted February 17, 2010 What keeps conductors from prematurely opening the doors at a station with gap fillers, such as 14th st. Union Square? Link to comment Share on other sites More sharing options...

bveguy Posted February 17, 2010 Share #3 Posted February 17, 2010 They have to wait for the gap fillers to come out, then open the doors. We don't want people tripping and falling in between that gap. P.S. There is a signal telling the C/R when its safe to open the doors.. Link to comment Share on other sites More sharing options...
SevenEleven Posted February 18, 2010 Share #4 Posted February 18, 2010 Also, if I'm not wrong, the T/O extends the gap fillers before enabling the doors for the C/R. Link to comment Share on other sites More sharing options...
LRG Posted February 18, 2010 Share #5 Posted February 18, 2010 Also, if I'm not wrong, the T/O extends the gap fillers before enabling the doors for the C/R. Negative; they are automated. That's why stopping at the marker is crucial. Link to comment Share on other sites More sharing options...
metsfan Posted February 18, 2010 Share #6 Posted February 18, 2010 Man, falling in the union sq gap would mess up your whole day. Funny, a few times train tried to move while the mechanism was extended, same at the south ferry loop. - A Link to comment Share on other sites More sharing options...

Man, falling in the union sq gap would mess up your whole day. Funny, a few times train tried to move while the mechanism was extended, same at the south ferry loop. - A The gap fillers contain a sensor, as long as the train stops at the mark give or take a window of a foot or so each way they will come out. They also contain a sensor when the train goes to depart. They detect the train's movement, then after the train has moved about a foot or two, they will retract back into the platform. A special gap filler signal about a carlength past the station indicates when they've been retracted to the T/O...this is why he will take min power for a couple of seconds, move very slowly, then the gap fillers come in, the gap filler signal clears and he will move the train quickly out of the station. Gap fillers are extremely expensive and must be obtained from certain vendors because of safety restrictions. A single section can cost 1 million dollars.

OK, I figured there was some sort of signal; other than just the usual zebra. Do the conductor boards look like zebras in the A, I'm not recalling?

EE Broadway Local Posted February 25, 2010 Share #11 Posted February 25, 2010 14th Street-Union Square is a station to be careful at when getting on or off a or train. Link to comment Share on other sites More sharing options...
jimbob60 Posted February 25, 2010 Share #12 Posted February 25, 2010 Perhaps a dumb question but why was the Lex line constructed with so many curves? Other stations between 14th St and Brkln Br are curved. When construction was done there over 100 yrs ago was there anything that crews had to build around? Did it have something to do with the property lines at street level? Most IND lines are fairly straight aside from where trains have to turn.

INDman Posted February 25, 2010 Share #13 Posted February 25, 2010 Most IND lines are fairly straight aside from where trains have to turn. The IND was built for speed. The IRT and BMT were not and were poorly designed compared to the IND. Link to comment Share on other sites More sharing options...
