The second day of the scorching heat wave saw a brief disruption of the 1, 2 and 3 lines in Manhattan, and evening power problems are snarling subway service in Queens.
The cold front, such as it is, has passed through, but troubles continue in Queens. Here's the latest service advisory.
As for the big picture, amNY takes a look at problems the subways endure during the heat.
"Extreme heat has an enormous effect, we go through it every summer," said John Samuelsen, chairman of the track division of the Transport Workers Union Local 100. "The running rails expand on hot days and the possibility of rail buckling grows exponentially."
And it's not just heat. We all know how heavy downpours or melting snow can bring whole lines to their knees. Here's a look at some of the more recent problems, compiled by amNY:
Friday June 2, 2006
Extensive rain causes train delays and cancellations, especially in
Queens.
Sunday and Monday, February 12 and 13, 2006
A snow storm slowed and disrupted more than 12 subway lines throughout
the city. Central Park received 26.9 inches of snow from the weekend
storm.
January 18, 2006
High winds delayed train service from Connecticut to New York City.
September 8, 2004
Immense downpours flooded tracks and caused signals to malfunction,
which stopped subway trains. Almost every subway line in the city was
delayed because of the rain.
August 4, 2003
Rain, one to two inches in certain places, caused the rerouting of the N
and R trains over the Manhattan bridge and the No. 2 train to the
Lexington Ave. line between Manhattan and Brooklyn. The No. 1. 9, 2, 3
trains were suspended as well.
