An engineer working on a moving walkway at Waterloo Station died in the early hours of this morning.
A South Western Railway service partially derailed in the Wimbledon area during rush hour, and disruption is expected to last for the day
The station has already endured heavily disrupted services throughout the month of August
Emergency services were called to the station after receiving reports of a loud bang
The incident occurred after a failure in the points system caused a South West Trains service to collide with a Network Rail wagon
Work should be completed by September, followed by a second phase of improvements
A number of platforms at the station are closed as a major engineering project began over the weekend
