[UPDATES BELOW] There are currently extensive delays on every single subway line, thanks to a power outage at the MTA's Rail Control Center in Manhattan.

The outage was first reported at about 1:17 p.m., and the MTA is currently using a backup power system. Trains are being dispatched locally, rather than remotely, which is what's backing up trains across the city.

An MTA spokesperson said there's not yet an estimate of when things will be running normally.

Check back for updates soon.

Update, 2:05 p.m.: An MTA spokesperson now tells us that the delays are confined to the 1, 2, 3, 4, 5, and 6 trains, and that they're due to an electrical issue, not a power outage.

Update, 2:45 p.m.: There are now also delays on the A, B, C, D, E, F, M, and G lines, due to signal problems.

Update, 3:07 p.m.: Delays have now spread to the 7 and 42nd Street S shuttle, as well. On the bright side, things are looking better on the A, B,C, D, E, F, M, and G lines, but no such luck on the numbered trains.

Update, 3:55 p.m.: The MTA now says that regular service on the affected lines has resumed with residual delays. Happy commuting!
