context_page_description: Pacer is the operational name of the British Rail Classes 140, 141, 142, 143 and 144 diesel multiple unit railbuses, built between 1980 and 1987. The railbuses were intended as a short-term solution to a shortage of rolling stock, with a lifespan of no more than 20 years.
  All Pacer trains were scheduled to be retired by the end of 2019. The Rail Vehicle Accessibility Regulations require that all public passenger trains must be accessible to disabled people by 2020. Only one Pacer currently meets this requirement, and the remainder were therefore planned to be withdrawn by that date. Furthermore, a decision in 2015 by the Transport Secretary required that such railbuses be removed from service by 2020 for the then-new Northern franchise, stating that the "continued use of these uncomfortable and low-quality vehicles is not compatible with our vision for economic growth and prosperity in the north".
context_section_description: The prototype was joined by another 20 two-car units which formed the Class 141 fleet. The units were used mainly in Yorkshire, operating on predominantly suburban services. They had a capacity of 94 passengers per two-car set, and two Leyland TL11 engines gave a total of 410 bhp (310 kW), resulting in a top speed of 75 miles per hour (121 km/h). 
  The 141s were built with standard Leyland National bodies, whose comparatively narrow width meant they could only be fitted with standard bus seating. The later Pacers had widened body panels to allow increased seating.
  The entire class underwent a technical upgrade in 1988 at the Hunslet-Barclay works in Kilmarnock. 
  The units were withdrawn from British Rail in 1997. Many were sold to Islamic Republic of Iran Railways but have been withdrawn and are left in disused sidings in Iran, whilst a few remain in preservation.
