Mainline Freight

Mainline Freight was created in 1994 along with Transrail and Loadhaul as part of the broadly regional split of British Rail's Trainload Freight operations – Mainline Freight's centre of operations were South East England, and East Anglia, and the East Midlands. Three companies were created with the aim of promoting competition between the businesses. It was initially and briefly named "Trainload Freight South East Limited" before being re-branded in September 1994.

All three former Trainload Freight companies including Mainline Freight were acquired in February 1996 by 'North-South Railways': a company formed by a consortium led by US railroad company Wisconsin Central, for a combined total of £225.15million (approximately $349 million). The management of Mainline Freight, backed by Candover and Associated British Ports also formed a bidding consortium for the three former Trainload Freight companies. The three companies together with Rail Express Systems were formed into a new company, English Welsh & Scottish (EWS).

Mainline Freight's fleet consisted of Class 08, Class 09, Class 31, Class 33, Class 37, Class 47, Class 58, Class 60 and Class 73 locomotives based at Toton, Stratford, Hither Green, Stewarts Lane and Eastleigh depots

Livery

The company introduced a livery of 'aircraft blue' with a silver bodyside stripe, and "rolling wheels" logo with Mainline branding. Some locomotives (particularly the classes 33, 37, 58 and 60) retained the Trainload Freight two-tone grey livery but with the addition of the Mainline Freight logo.
