<p>Social distancing and 'doors not for passenger use' signs on the door window glass of a London Docklands Light Railway (DLR) B07 train.

The reason for the closure of this part of the train is that normally DLR train staff walk about the train, interacting with passengers etc., but for their safety it was decided to give them a reserved area where they  can oversee the train and remain socially distanced.
