Rail Express Systems was a sector of British Rail. Upon the sectorisation of British Rail during the 1980s, the Parcels Sector was created. In 1991, this was re-branded as Rail Express Systems. The Rail Express Systems launch event was held at Crewe Diesel Depot in October 1991. For this event, examples of Class 08, 47, 86 and 90 locomotives were painted into a new livery of red, with a grey upper band, and light blue and grey flashes. The light blue and grey flashes represent a set of stylised eagle's wings.
