'''4150''' is a GWR 5101 class 2-6-2T locomotive, commonly referred to as a 'Large Prairie'. It is the only SVR-based locomotive not to have steamed in preservation. Large prairie tanks were a common sight on the GWR, with more than 300 built between 1903 and 1949 to the same basic design. The locomotives were designed to haul semi-fast and suburban passenger services to tight schedules, and were also used on medium distance freight services. A number brief description of the class were allocated to [[Kidderminster]] and [[Shrewsbury]] sheds and were regularly used on the Severn Valley Railway in its declining years. Classmate 4175 was involved in the [[Level crossing at Hill Farm, Northwood Lane#Accidents in the BR Era|fatal accident at Northwood Lane level crossing]] in August 1964. The 5101 Class was an updated version by CB Collett of Churchward's 1903 3100/5100 Class. Fellow class member is included in [[GWR Large Prairie 5164]] is an early 1930 example, while 4150 is a later post-War example. The 41xx number arose from the GWR practice, where more than 100 locomotives of one class were built, of maintaining the second number in the series and re-using older sequences of numbers where necessary. The prevalence of the Large Prairie also resulted in examples numbered 61xx, 31xx and 81xx.<ref>[http://www.greatwestern.org.uk/m_in_262.htm Great Western Archive]</ref>
