A train derailed northwest of London on Friday morning after hitting a landslip, causing travel nightmares for morning commuters.
The train traveling south to London hit a landslip near Watford Junction station shortly before 7 a.m. BST at the north end of the Watford Tunnel, according to a statement from Network Rail. A small section of the train's wheels left the track.
Network Rail states that the landslip was "caused by torrential rain."

"The train remained upright and there are no reported passenger injuries," Martin Frobisher, route managing director for Network Rail said.
Shortly after the incident, "another train heading north had a glancing blow with the derailed train," according to the statement. "The train heading north did not leave the tracks."
National Rail is reporting "major disruption to services between Milton Keynes Central and London Euston."
Two of the lines have reopened but at a reduced speed.
"Journeys are expected to be delayed by up to 60 minutes, revised or canceled," the National Rail said.
Downpours and thunderstorms developed across southern England, including the London area, late on Thursday. Additional storms developed overnight, leading to the inundating rainfall.
Runoff from the heavy rain has flooded various train lines in southern England, National Rail also reported. Some street flooding was reported in London as well.
The wet weather occurred due to the combination of a slow-moving depression over France and an advancing cold front.

The cold front has erased the summer heat from this week. A drier and more seasonable weekend will unfold in its wake around London.
Both days of this weekend will feature sunny spells with highs trending upward from 18 to 21 C (64-69 F).
