18th May 2017 Colas Rail Freight has returned a large amount of previously preserved locomotives back to the mainline in order to operate many of its Network Rail test train. One such example is split headcode example No. 37099 'Merl Evans 1947-2016' (37324). The locomotive spent many years in preservation at the Gloucestershire and Warwickshire Railway in BR Blue livery wearing its 37324 number, later it moved up to the East Lancashire Railway. During 2016 the locomotive returns to mainline operations with Colas Railfreight and was renumbered back to 37099 'Merl Evans 1947-2016'. On Thursday 18th May 2017 the locomotive is seen passing Taunton while working the 3Z53 07:57 Exeter Riverside - Crewe test train. (Photo: Thomas Courtney)
