Rush-hour commuters are being hit by delays on the Metropolitan line this morning after a signal failure.
There is no service between Baker Street and Aldgate because of the problem at Moorgate, with minor delays affecting the line up to Harrow-on-the-Hill.
The delays are compounded by severe delays on the Circle line and the M25, and no step-free access to platforms at Harrow & Wealdstone and Wembley Park due to defective lifts.
