"Mechanical Problems"

[Juelz4309]

Why does it happen when a train has "mechanical problems" BOTH directions get affected? What does one side have to do with the other?

 

ie: "due to a train wit mechanical problems at

219 street there is no Trains in both

Directions between E180 and 241 Sts"

 

Do they have to shut down the power to the tracks in order to fix the train? Cant tell u how many times Ive been cuaght up in this mess

They get affected because there is no tracks to cover cut service in one direction. At least I am assuming so.

It depends on a lot of things. The location and expected duration of the problem plays a large part in determining whether they shift service to the express/local tracks, divert service to another line or call for a partial suspension. On two track lines like the Canarsie, there is no way to bypass any incident without switching onto the opposite track and thus delaying the entire line. Things are a little more flexible as you increase the number of tracks along the line as well as when the number of reroute options goes up. Rather than completely suspend service, Transit would be more likely to reroute service to the express or local tracks as the situation warrants, or even divert service to another line entirely, which is why you see so many   s via Lexington Ave and   s via 7th Avenue. The idea behind all of this is to keep overall service running as smoothly as possible despite the incident affecting the line.

 

In the example provided, a complete service suspension between E 180 Street and Wakefield would probably be avoided unless there was a problem at 241 Street or both sets of switches at Gun Hill Rd were malfunctioning. However, some trains would likely be turned at Gun Hill Rd or E 180 Street so as to prevent a logjam at 241 Street.

Lately they been having a midday G.O where the runs express in the Bronx between 241st and Gun Hill, so they only have two tracks available for service rather than three. IDK if they had the G.O today though.

There are a lot of reasons why this could occur.

 

I.E

 

Due to a train with mechanical malfunctions at 72nd St, southbound and trains are running local from 96th St to Times Square-42nd St.

 

In this case, the train with mechanical problems at 72nd St is stuck on the downtown express track. Since 7th Avenue is 4 tracks, two express tracks and two locals, there are a lot of options that can be done here. The easiest reroute now is to reroute all southbound and trains from the express track at 96th St to the local track and then resume normal service on the express track at Times Square. Of course this is going to bottleneck the local track severely and affect all three lines services, but its the easiest that they can do.

 

But here's the thing, if something happens on 7th Avenue that affects service, the can easily get rerouted via the from Nevins St to 149th St and vice versa. This is because there are two switches in the Bronx and Brooklyn that allows these changes to happen, as to what Lance said.

 

Now if its the , if something happens on one track, the whole entire line gets screwed which is part of the reason why they didn't go with the three year partial shutdown in the tubes. If something happens at Bedford that knocks out the uptown track, then that screws up the downtown track.

Speaking of which I think there should be express service between East 180th street and 241st street outside of the rush. I had a session in Westchester for Regents prep recently and was staying in Manhattan... Took the BxM10 to East 180th street, transferred to a express train that was super quick to East 241st street. Basically 4 stops from 86th and 3rd...

There's not enough demand for rush hour express service between E 180 Street and 241 Street, much less so for other parts of the day.

I'm thankful for the engineering geniuses that designed the IRT and made it as flexible as it is. Last week Friday when the rail cracked at Chambers on 7th ave the 4 I was on rerouted via local to cover the 3. By the time we got to Utica it was announced the train wouldn't go to New Lots anymore because the problem was fixed and service was near normal. I was coming from Manhattan, but it beats waiting on a hot platform waiting for a delayed train.

 

It was cool seeing a train relay on the local track too.
