Overground trains out of Enfield Town were severely delayed on Friday due to power problems.

A failure of overhead lines at Seven Sisters have caused trains to run late or be cancelled between Liverpool Street, Chingford, Cheshunt and Enfield Town.

The problems began at around 4pm, with no service on the line for almost an hour and a half.

Tickets were accepted on other routes, with service returning almost to normal by 6pm.

It was only three days since the route was last hit by bad delays.

On Wednesday (April 27), the journeys of morning communters were hit by engineering work running late from the previous night.

Commuters took to Twitter to vent their frustration.
