D6817 (37521) makes a fine racket as it gets away from Northampton approaching Milton Malsor towing former East Midlands Railway's HST power cars 43046 and 43055 with Mk.III 10416 sandwiched in the middle. Whilst the Mk.III was simply acting as a barrier the power cars were being taken to Eastleigh's Arlington Fleet Services' facility for attention. The train, running as 5Z36, left Crewe at 07.14 receiving a lot of attention by enthusiasts en route with plenty of updates. One observer was one of my railway chums, Mike, who had gone to see the train pass through Northampton station.
