Hi all,
I hope I have put this in to the right area on the forum...
I wanted to ask some people here who are either from New York or know stuff about the New York Subway a question.
Right, so I have been researching the NYCS for a couple of months now, and I think I have gotten to know some of the basic terminology of the Subway.
However, there is one thing I really want to find out-
Basically, there are many videos of the NYCS on YouTube, and quite a few of them are of the 5 train which mainly operates on a line called the Lexington Avenue Line, and sometimes is diverted on the line on which the 2 operates, which is the Broadway-Seventh Avenue Line. I have noticed that when the 5 operates on the Bdwy Seventh Avenue Line because of a General Order, which I think means engineering work in our terminology, the 2 train runs on the Lexington Avenue Line. I think this is strange because all that has happened is that they have switched lines. Why? What causes them to switch over lines?
Thank you,
Uzair

Yes, a General Order is an engineering or other out of the ordinary notice. A combination of a T/C & EWSA.
Switching lines for engineering work is quite common but does require a 'G.O'. The 1,2, 9 lines run under the west of Manhattan and the 4,5,6 run on the east (under Lexington Avenue).

The 1,2, 9 lines run under the west of Manhattan It is actually the 1, 2 and 3. The 9 doesn't exist any more. |

Put your question onto "Subchat" (Google it) - plenty of NY experts on there. NYSubway.org is also a mine of information
All sorts of things happen on engineering alerts - e.g 4 express running as 6 locals on the Lexington Ave line.

Large amounts of the NYC subway is two or three track and still has 24 hour traffic, and on the four track sections one of the pairs is timetabled to be in use 24/7. If you check the engineering notices, there just aren't enough for these to get significant amounts of time off.
The key is that the overnight services are only half-hourly, and maintenance work is organised to be done around these trains rather than closing the lines fully overnight. Whether LUL could ever organise maintenance in this way I don't know, but I consider it far more important than the four-tracking excuse that's normally mentioned.

Switching lines is very common in NYC operations. The system has many non-passenger connections which are used for engineering work diversions. I have been over most of these as a result of my time doing train testing in New York in the early 80s.
It was not unusual to find the wrong train on the wrong line without any notice to passengers. The most irritating is when the local is diverted over the express and skips several stations. You then have to go back on the local running in the opposite direction.
It is easy for IRT trains to switch from the east side to the west side. They use the Grand Central-Times Sq shuttle tracks which have connections at both ends. This was the original IRT route opened in 1904.
And they do have a completely different language e.g. "There's a dog against the wall" means "there is a D Train on the local track".

My mind must be going to mush with my advancing years, but it certainly did have a through connection. |
