A very strange working pictured at Compton Beauchamp (between Didcot and Swindon) on 30 April 2007. 153369 & 158817 were booked to work the 5F77 Reading to Westbury empty stock move and indeed started out along the Berks & Hants Line, which is the obvious direct route. However, for some unexplained reason, after getting nearly half way there they reversed and came back to Reading, and then traveled via the west curve and continued to Westbury via Swindon! Neither Class 153 or 158 units are a common sight on the GWML, and certainly not with Taunton on the destination blind!
