Because of an incident closing down Stratford Station tonight, Jubilee Line trains were dumping passengers out at West Ham in their hundreds - official advice was to take a 276 into Stratford. When one did finally arrive people swamped in through both doors. Driver wasn't having it and killed the engine.
The days of the 276 as 'backup option' to the Jubilee Line should end soon with the opening of the Stratford International leg of the DLR. The sooner the better!
