The final HST? 43198 Oxfordshire 2007 is certainly the final production power car, and it can't be long before the final HST traverses the Swindon to Gloucester 'Golden Valley' route. The green liveried power car brings up the rear of the 1G14 09:38 Swindon to Cheltenham Spa GWR service at Westley Wood (between Frampton Mansell and Chalford) on 30 December 2018. 43161 has already passed underneath the impressive Jackdaw Bridge, and is leading the train down the valley of the River Frome, towards Stroud.
