Nexus, the public body which owns and manages the Tyne and Wear Metro, is putting more cleaners on board its trains.
This forms part of the plans to improve Metro services for its 38 million customers, following the end of the Metro operating contract with DB Regio.
Nexus resumed the direct operation of Metro on Friday 1 April.
The extra cleaners, which are being provided by the Metro cleaning contractor Churchill Services Ltd, will initially be deployed on the busiest lines operating between South Gosforth and Gateshead and Monument and North Shields.
Extra cleaning of the trains’ floors will happen at terminus stations, while Metro stations are to be cleaned more frequently.
Director of Rail and Infrastructure at Nexus, Raymond Johnstone, said: “This is just one of the ways that we want to make Metro better for our customers.
“We’ve now got more staff on duty to collect litter on board our trains, which will help to improve the quality of daily journeys.
“Cleaner and more punctual trains are something that our customers want and we are going to ensure that we deliver on that.”
Operator DB Regio, which had run services on behalf of Nexus since April 2010, came to the end of its operating contract at 2am on Saturday 1 April.
