Operator West Midlands Trains (WMT) has signed a contract with Vivarail for the supply of three upgraded Class 230 units in the UK.
An announcement revealing the two parties had struck a deal was initially made in March.
The two-car trains, which are converted London Underground D78 Stock, will be used on London Northwestern Railway services between Bedford and Bletchley from December following an extensive overhaul at Vivarail’s Long Marston depot, Warwickshire.
Vivarail CEO Adrian Shooter said: “Everyone is pleased with the look and build quality and I’m very proud of the work my team has done.
“I am particularly impressed with the London Northwestern Railway livery and their interior designs – they certainly showcase the Class 230 and I think will be well received by Marston Vale’s passengers.
“It is a proud day for me to see this first train roll out of our workshops and I am looking forward to seeing it at Bletchley depot in the near future.”
The trains will be supplied as diesel units, with the capability to convert to battery units in the future. They will include universal access toilets, USB sockets and modern ‘airline’ seating.
The Class 230 units will be maintained at the Bletchley train maintenance depot.
