A Docklands Light Railway train headed towards Woolwich is said to have filled with smoke last night.

A man took to the Facebook group Plumstead People to ask if anyone was on the train around 10.30pm last night (January 2).

He described a terrible burning smell and then the carriage filling with "toxic smoke" while in the tunnel under the Thames.

Since it was pulling into its final stop, it seems that people were easily able to get off and escape the situation.

A woman replied to say that soon after the incident she saw a lot of maintenance men headed towards the obviously damaged train.

She said: "Not sure if technical fault or pranksters messing around as there were idiots on the escalators."

TfL has been contacted for comment.
