This makes no sense....how does one derail and affect all service, there's at least one side of the line, granted, 3 tracks on the line that isn't affected.

Can we go back to normal scenarios on this thread? If we have a volcanic eruption in this city we’ve got better things to worry about than how to reroute trains...

Yep.  Here's one that is "normal:"

The switches in the vicinity of the platform at Chambers have gone all FUBAR and will need two weeks to be properly replaced.

There is a crime scene investigation going on on the upper level of 81st Street on the CPW line, requiring all trains use the express track on that level and closing off that station to passengers (southbound trains are unaffected with regard to traveling through the station, but they can't stop there).

Switches at West 4th are such where all trains on the 8th Avenue local tracks must go to the 6th Avenue line in both directions (northbound to 47-50, southbound to Jay Street).  

There is a rail condition on the northbound Broadway Local track inside the 57th Street-7th Avenue station as well as another on the southbound local track in the area of 28th Street.

For the record, if a  overshot Broad St, it would affect only  and  service, not also the Montague St tunnels. However, I'll humour you in this scenario.

: Runs via  after 34 St until Canal St.

: Runs from Jamaica - 179 St to Bergen St and from Church Ave to Coney Island.

Next (AM Rush):

A terrorist organisation attempting to attack City Hall detonates explosives in a  train on the City Hall loop, causing a cave in of the  and  tracks above. No trains may pass on either level.

A major signal fault occurs at W 4 St, meaning that no train (with the exception of the 8th Ave express tracks) can be sure of where it will go, and as a result, you are advised to terminate all service through the station.

A Transit Museum heritage train stalls at Rogers Junction (east of Flatbush Ave on the Eastern Pkwy line), meaning no Manhattan-bound trains can pass through.

The first thing I would to do is to shut down the entire system for safety reasons.

But anyway...

 no service between Wall Street and 42 Street

 no service between East 180 Street and Flatbush Avenue

 no service between Brooklyn Bridge and 42 Street

and for extra safety, I would send  down the Bridge, suspend , and terminate  at Chambers or Essex

 no service between West 4 Street and 34 Street

 no service between West 4 Street and 34 Street

 runs via  between Jay Street-Metrotech and 42 Street and via  between 42 St and Roosevelt Avenue in both directions

 via Nassau to Chambers or Essex

 local between 59 and 125 to replace

 suspended

 express between Canal Street and 42 Street

 no service between Atlantic-Barclays and Flatbush Avenue

 no service between Utica Avenue and Chambers Street. Trains run between Harlem-148 Street and South Ferry

 no service between Atlantic-Barclays and Utica Avenue

no service between Bowling Green and Flatbush Avenue

Next:

This time, a third fight on  ended up disastrous and one of the executives hit a collection of switches. This shut off power west of Broadway (exclusive) between Houston Street and 57th Street (inclusive).

For a weird reason, the switches south of 59 St and the tracks that  use between 59 St and 7 Av has still has power. You can terminate trains at 34 St, there's enough power there.

Also, there is a partial power outage in Seventh Avenue Line between Columbus Circle and Houston Street. You can send trains here, but if you try to send over 10 TPH between Columbus Circle and Houston Street, it loses power. This affects both directions.

Summarized:

West of Broadway shut off, but Broadway is not affected. This only happens between Houston and 57th Streets.

However, the power was still not turned on in the  tracks between 59 St and 7 Av.

And lastly, a partial power outage means you cannot run over than 10 TPH between Columbus Circle and Houston Street.

Area affected:
