In 2007 Brush Traction and Hitachi equipped Paxman Valenta powered 43089 and a semi-permanently coupled Mark 3 coach with a diesel-battery hybrid power system for experimental trials. The power car was named "Hayabusa" ("Hayabusa", はやぶさ, Japanese for Peregrine falcon, project name 'V-Train 2'). It returned to normal service with East Midlands Trains.
