In a similar vein, how do relays at Forest Hills work? Do trains use the lower-level/yard tracks, or cross over the active, express tracks?

I don't want to seem patronizing, but are you joking? Think about it, there are 30 TPH going via the express tracks, and 20 local trains. They clearly go via the relay tracks.

Does Union Turnpike have a lower level?

The tracks are only under part of the platform.

Alright, that makes sense. Some track maps aren't very clear about it is all

look up r train bve on YouTube, it shows how the relay is done at Forest hills. I would post it but I'm on Mobile.

R46 and R68 has the same acceleration which very good but R160 has a bit faster acceleration. I like R46 and R68 because of the seating arrangements especially by the window and longer cars.

The NTTs are lighter than the 46/68s (68s being the heaviest in the fleet). This is whybthe NTTs are faster. Weight is always a factor in speed.

Anyone know why the seems to be prioritized over the whenever there are delays? During today's West 4th Street signaling debacle, my Manhattan-bound sat in the tunnel before Hoyt-Schermerhorn for 15 minutes while five (A)s went by, and this happens probably once a week. Is it more efficient to not move the switch back and forth or something?

A trains get priority over the C. The C is a local supplement of the A.

There's a lower level with 4 tracks that they use. Those tracks lead to the Jamaica yard.

 

As for Union turnpike, there's tracks on the lower level leading to Jamaica yard from the east and merge with the tracks from the west (Forest Hills).

that's completely unfair and i really do not like that statement. just because it is a part-time or local supplement doesn't mean they should have passengers sitting in the train for a good 15 or more minutes just so a full time line can get priority.

Well think of it like this, you have a C train, on time or even a few minutes early. And you have the A, which just had a delay back trains up. Its common practice among railroads. It may seem unfair to you being on that C, but overall, its how a railroad functions. Its it unfair if those express riders on those trains and those waiting for stations up ahead, to have them wait longer. "The needs of the many...."

It happens. Its not every train. But certain lines have priority over others. Fact is the A has more riders and trains than the C. Simple as that. If been on, and worked on, plenty of A trains that were held to allow a C to cross cause that was how the schedule is made. If that C is late, the A will wait (as long as its within a reasonable time or the A is early). Remember, if the A gets delayed northbound, then soon downtown trains will gap. And that will affect other lines it comes across.

Think of it this way too, last week there was a switch problem. A trains had to run local in place of C trains. Was it fair to those A riders to board an express and wind up on a local? For their trips to now take longer? To get more crowded trains that are now serving two lines? I understand your frustration, but that responds was kinda childish (NO disrespect there).

Dispatching a railroad is difficult. And certain trains have priority. Do you know that the E has a high priority even on 8th ave? Unfortunately the C isn't high on the totem pole. Look at the B. It gets suspended when a major delay happens. At least with the C they'll adjust, reroute or split it before it gets suspended.

It would be cool if in that case the could just pull into Hoyt Schermerhorn on the Local Track, let people cross over to one of the many trains passing, then (reverse back to the switch and proceed to Manhattan when the coast is clear.

Headways are one thing that won't allow that operation. As well as how long that relay would take to pull off. And those platforms are closed. Have been for years. Its actually quicker to just hold the train.

Also about rolling stock, I've noticed R160s more frequently on the lately, and even a few more R68s on the and than usual. Has there been a recent shift in where different train models go, or is this common?

The switch is just east of the station how long could it take theoretically?

if the train was held for 15 mins what's the difference? haha

Where do I begin?

One,those platforms are closed. No conductor indication boards. Gates are locked. No proper platform edges. No proper lighting etc.

But here's how a move like that I'm would be done and why it never will:

Train pulls in opens doors. T/o moves to other end of train. Waits for the line up(signal) when a space is available(which it won't). Once clear of the original switch, T/O walks to the original end of the train and waits for the proper line up again.

If you think this is better than a 15 min wait, 1)you have a lot more to learn about operations 2)I got a bridge in Brooklyn to sell you.

Hypothetically I was thinking of the train backing up on the local track to where the train originally was waiting, Then crossing over to the express track as usual.  And if the trains were held for 15 mins anyway then the the following could have been held at Clinton Washington or something.

Same move pretty much and same problems. And now you're delaying two trains.

Fact is, those platforms are closed. The gates are locked. And more importantly, there's no C/R boards. If a c/r were to open doors with no board they are taken out of service. And a move like that doesn't fly in the subway. Simple as that

What happens if a board falls on an active platform?

[Far Rock Depot]

The c/r MUST NOT open the doors and contact Control for instructions. (They actually test C/Rs on that)

I remember I once had this train operator and conductor who were new to the line a few months back, the operator stopped at the 10 car marker instead of the 8 car marker at 14th Street because he was used to only operating the . The conductor had a freak out because she couldn't see the CCTV screens (I don't know why you even need CCTV screens since the platform is straight anyway.) And the board wasn't in sight. RCC and her operator were telling her two different things so she opened the doors but couldn't close them because she coudlnt see the CCTV. Her operator had to walk out of his cab and try to explain to her what was going on. This delayed service on the by like a good 15 minutes.

If its 14th northbound, the last car is on a curve so you can't see it from the C/R position.

This morning I saw a R68a with a door that wouldn't open.

You'll see that from time to time on almost every line...
