In February 2020, a further three were ordered to allow services to be introduced the Midlands to Scotland via the West Coast Main Line.[5] A further five has since been ordered. Originally to be classified as Class 769/5s, they were reclassified as the Class 768 before the first unit was completed.[6]
The first units received their traction conversions at Brush Traction, Loughborough, while the latter examples will be completed by Wabtec at Doncaster Works. They then move to Eastleigh Works where Arlington Fleet Services fit out the interiors and fit roller doors to carry pallets, bulk items and parcel cages.[6]
The units will operate in fixed formations of four (capable of running in multiples) at up to 100 mph. Unlike conventional rail freight, this provides direct access to city centres, with onward distribution from stations to be by van or bicycle courier. A demonstration from London Euston took place on 7 July 2021.[2][7]
