High Speed Freight Vehicle
The High Speed Freight Vehicle was a generic term for a number of prototype four-wheeled rail vehicles which were fitted with various experimental suspensions developed by the British Rail Research Division in the late 1960s. The development was part of the investigation into the riding of vehicles and the interaction between wheel and rail. HSFV1 was intended for fundamental empirical research into wheel-rail interaction and suspension dynamics to be better understood, following from work on wheel tread profiles. It was regularly run at speeds of up to on the Vehicles Laboratory's roller rig. It also performed at whilst under test on the main line. Its suspension had two vertical coil springs and two vertical and one lateral hydraulic damper at each corner of the vehicle. This was at a time when few freight trains travelled at more than and most passenger trains averaged about . It supported theories of vehicle design which led to most later designs of train.

British Rail Research Division
The British Rail Research Division was established in 1964 directly under the control of the British Railways Board, moving into purpose-built premises at the Railway Technical Centre in Derby. The intention was to improve railway reliability and efficiency, while reducing costs and improving revenue. In so doing it became recognised as a centre of excellence and, in time, was providing consultancy to other railways around the world. While it became famous for the Advanced Passenger Train (APT), its activities extended into every area of railway operation. The theoretical rigour of its approach to railway engineering superseded the ad hoc methods that had prevailed previously. Work The Research Division brought together personnel and expertise from all over the country, including the LMS Scientific Research Laboratory. Its remit was not simply the improvement of existing equipment, or the solution of existing problems, but fundamental research from first principles, into railway ...

Leaf Spring
A leaf spring is a simple form of spring commonly used for the suspension in wheeled vehicles. Originally called a ''laminated'' or ''carriage spring'', and sometimes referred to as a semi-elliptical spring, elliptical spring, or cart spring, it is one of the oldest forms of vehicle suspension. A leaf spring is one or more narrow, arc-shaped, thin plates which are attached to the axle and chassis in a way that allows the leaf spring to flex vertically in response to irregularities in the road surface. Lateral leaf springs are the most commonly used arrangement, running the length of the vehicle and mounted perpendicular to the wheel axle, but numerous examples of transverse leaf springs exist as well. Leaf springs can serve multiple suspension functions: location, springing, and to some extent damping as well, through interleaf friction. However, this friction is not well controlled, resulting in stiction and irregular suspension motions. For this reason, some manufacturers ha ...

Hydraulic
Hydraulics (from Greek: Υδραυλική) is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. At a very basic level, hydraulics is the liquid counterpart of pneumatics, which concerns gases. Fluid mechanics provides the theoretical foundation for hydraulics, which focuses on the applied engineering using the properties of fluids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids. Hydraulic topics range through some parts of science and most of engineering modules, and cover concepts such as pipe flow, dam design, fluidics and fluid control circuitry. The principles of hydraulics are in use naturally in the human body within the vascular system and erectile tissue. Free surface hydraulics is the branch of hydraulics dealing with free surface flow, such as occurring in rivers, canals, lakes, estuar ...

Electric Railway Museum
The Electric Railway Museum (formerly the Coventry Railway Centre) was located in Warwickshire, south-east of Coventry, near the village of Baginton. The heritage railway centre was immediately adjacent to Coventry Airport and so it was also known as "The Airfield Line". The site was managed by the Electric Railway Museum Limited, and was home to a sizeable collection of preserved electric multiple units (EMUs), which was the most diverse and historically significant collection of EMUs in the UK, containing unique items that are the last survivors of once typical and numerous classes. In addition, there were small industrial electric locomotives, two small industrial diesel locomotives, and one small industrial petrol locomotive, along with some other railway vehicles, which are owned by third parties. The land was leased from Coventry City Council, though it is located just outside the city boundary and is in the county of Warwickshire. On 9 July 2017, it was announced tha ...

British Rail Class 140
The British Rail Class 140 was the prototype of the ''Pacer'' diesel multiple unit. It was constructed between 1979 and 1981 in response to a desire within British Rail to develop a capable railbus for its smaller branch line services. Much of the bodywork was constructed using Leyland National bus components, with the exception of the cabs. Based on the single car railbus prototypes, the Class 140 was built to BR's then stringent regulations regarding crashworthiness and resistance to end loading; as such, much of its intention lightweight 'bus on a wagon' look was lost, becoming a more substantial vehicle. Throughout the 1980s, the sole member of the class functioned as a trials and demonstration unit, acting as a herald to the closely-related Class 141. Since its withdrawal, the unit has been preserved at the Keith and Dufftown Railway. Background By the beginning of the 1980s, British Rail (BR) operated a large fleet of first generation DMUs, which had been constructed ...

Pacer (train)
Pacer was the operational name of the British Rail Classes 140, 141, 142, 143 and 144 diesel multiple unit railbuses, built between 1980 and 1987. They were inexpensively developed using a passenger body based on the Leyland National bus on top of a chassis based on the HSFV1 research vehicle. The railbuses were intended as a short-term solution to a shortage of rolling stock, with a lifespan of no more than 20 years. As modernised replacements were lacking, the Pacer fleet remained in service on some lines until 2021 37 years after their introduction in 1984. All Pacer trains were scheduled to be retired by the end of 2019 as the Rail Vehicle Accessibility Regulations require that all public passenger trains must be accessible to disabled people by 2020 however the Pacer units were given dispensation until the end of 2020. Only one Pacer (the modernised 144e) met this requirement, and the remainder were therefore planned to be withdrawn by that date. Furthermore, a decisio ...
