Greater Anglia is continuing to test it's new electric trains amid the coronavirus outbreak.
The company says they are following all government guidelines to ensure that the workforce is kept as safe as possible.
One of the new electric trains completed its maiden voyage to Liverpool Street recently - a journey the company says was a success.
The trains will replace the company’s old trains used on lines into London from Essex, Cambridge, Hertfordshire and Ipswich.
Made by British manufacturer Bombardier, the trains will have to complete several test runs as technicians check how the trains interact with the signalling system.
The train will have to travel over all of the electrified network at least twice in various different conditions.
As part of this testing, the train has also been on West Anglia line up to Cambridge and Kings Lynn.
On the Great Eastern Main Line, the train has been to Norwich, although the 111 trains Greater Anglia is getting from Bombardier will mainly be used south of Norwich.
