Thus, various initiatives were undertaken, including the procurement of new rolling stock in the form of 16 four-car British Rail Class 325, a series of electric multiple units built exclusively for moving mail.

During the mid-1990s, RES implemented a £150 million strategy that focused on long-distance services that worked in conjunction with a central hub based in London at its heart, known as Railnet.

[1] Under the policy of Sectorisation, BR's entire rail-based mail operations were consolidated into their own business unit, Rail Express Systems (RES).

[4][5] Seeking to rejuvenate rail mail, RES devised a £150 million strategy that focused on long-distance services that worked in conjunction with a central hub based in London at its heart, known as Railnet.

Furthermore, RM commissioned ABB to manufacture 16 four-car British Rail Class 325 electric multiple units, which were designed exclusively for the transport of mail.

[1] In place of passenger stations, these services were directly to a number of mail hubs at strategic locations; these were: Shieldmuir (Motherwell), Low Fell (Gateshead), Warrington, Doncaster, Bristol Parkway, Tonbridge and Wembley PRDC (London) as well as dedicated platforms at Stafford.

[1] As part of the privatisation of British Rail, RES was the first freight company put up for sale, with bids lodged by Freightliner, a management buyout, Serco and a Wisconsin Central led a consortium known as North and South railways.

In the same period, Class 325 EMUs were introduced and the entire parcels and mails fleet (except the travelling post office stock) was refurbished or withdrawn.
