It appears this morning's commute-snarling track fire was so popular, the MTA has gifted us with an evening sequel. As of 5:30 p.m., there are widespread problems on the subway, with 4, 5, 6, 7, A, C, E, N, R and W trains experiencing delays. And it's still early!

The 7 train is experiencing signal problems, as is the E; C trains are running express from Canal St to 59 St-Columbus Circle thanks to switch problems, and FDNY activity at Lexington-63 St has caused backups on the N, Q and R trains. There's also a sick customer at 96 St on the East Side, so 6 trains are running with delays. The MTA's website shows good service on the B, D, F, M, J, Z, Q, L, 1, 2, 3, and G lines, but Murphy's Law suggests at least four of those lines will drop you off in the wrong borough by the end of the day.

Are you tired? I am very tired.

Good luck, comrades.
