The Clayton Type 1, later British Railways Class 17, was a class of 117 Bo-Bo diesel-electric locomotives built between 1962-65 by Clayton Equipment Company and Beyer, Peacock & Co. The twin Paxman engines proved to be unreliable, being prone to camshaft and cylinder head problems amongst others, and at any one time only 60% of the fleet were available. Their career with British Rail was short lived because of this, the first being withdrawn in July 1968 and the last in late 1971.

The D1/3 Class diesel shunters were built by Ruston and Hornsby Company and were specifically designed to work dockside tramways for the Eastern Region of British Railways. With only a 5 ft 6 inch wheelbase they could work the tight curves and awkward areas of the East Anglian dock systems. They were withdrawn in 1967 as part of a purge of non standard shunters, One being cut up in 1968 while the other was sold for industrial use before being scrapped in 1983.

The North British Type 1 (later known as Class 16) were ordered under British Railways' 1955 Modernisation Plan. They were intended primarily for local freight traffic. Ten were built but were not a success, problems with their Paxmen engines causing them to have a high failure rate. Being a non-standard design and unreliable, they were an obvious candidate for early withdrawal which was carried out between February and September 1968, all ten being cut up for scrap by the end of 1969.

In 1957 British Railways began a series of trials with lightweight railbuses on selected rural branchlines and small orders were placed with five manufacturers, one of them being Waggon und Maschinenbau GmbH in Germany, who supplied five 150 hp four wheel diesel railbuses for use in the Eastern Region. After initial trials on the Witham branch in Essex, these railbuses were sent to the Saffron Walden, Mildenhall and Haverhill lines in 1958, where they completely replaced steam traction.

The Class 55 diesel locomotives entered service in 1961 and were designed for the express passenger services on the East Coast Main Line between Edinburgh and London King's Cross. The design was based on the prototype English Electric DP1 Deltic, with twenty-two locomotives being built which dominated express passenger services on the E.C.M.L., particularly from London to Leeds and Edinburgh, until 1978 when the Class 43 High Speed Trains (HSTs) took over their role.

The Class 91 locomotives were ordered as part of the East Coast Main Line modernisation and electrification programme of the late 1980s. The streamlined design of the locomotive allowed high-speed operation of up to 140 mph with a fixed sets of coaches, while a second cab at the blunt end allows them to operate as normal locomotives subject to a speed restriction of 110 mph. When British Rail was privatised in the mid 1990s the Class 91 fleet has had various liveries after franchise changes.

The English Electric DP1, commonly known as Deltic, was a prototype 3,300 hp demonstration locomotive that was powered by two Napier Deltic engines, that appeared in 1955. The locomotive was first trialled by British Railways on the London Midland Region, and following further trials, the design was accepted by British Railways for use on the East Coast Main Line express passenger services. The Deltic was retired in 1961, the same year the first of the Class 55 diesels entered service.

The Class 03 locomotive, along with the similar 04 Class, were one of British Rail's most successful 0-6-0 diesel-mechanical shunters. In total the class consisted of 230 machines which were built at Swindon and Doncaster works between 1957-1962. Like other shunters of their size they were built for light branchline duties, while their short wheelbase and light weight enabled them to operate on lines where weight restrictions prevented the ubiquitous Class 08s from operating.
