Expect delays on the westbound Central Line after a train derailed between Mile End and Bethnal Green at approximately 9.15am.
The Central Line is currently suspended between Leytonstone and Liverpool Street in both directions.
The TFL website is just saying there is a "faulty train in the Mile End area" but we got the information on the derailment straight from the mouth of the driver of the train directly in front of the affected one, so make of that what you will.
We're fairly sure terrorism isn't the cause of the derailment, as other services were unaffected.
In any case, make sure you check with TFL before you travel.

Update #2: Londonist contributor Talia says: "Bethnal Green is cordoned off and surrounded by about 7 police vans, 3 unmarked cars, 4 fire engines and 5 ambulances..."
