In connection with the Bedford River Festival a special train service was in operation on the Bletchley to Bedford line on Sunday 29 May 1988. This was something of a novelty as to save opening all the many signal boxes there was not normally a Sunday service on the line at the time. The highlight was the use of the green liveried Class 105 vehicles 54122 & 53359, which had been repainted into something approaching the original green livery a couple of years before. As a yellow warning panel had to be included, the original wasp stripe was added to this panel in black. With 54122 leading the unit is pictured arriving at Kempston Hardwick in a brief patch of sunshine with the 10:55 Bletchley to Bedford service.
