Transition time at Circourt Bridge, Denchworth, when it was (nearly!) a three track main line. The two relief lines were reinstated during 1992-4, with the down line being completed first. This is the scene on 21 February 1993, with the down line layed, but clearly not straightened yet. 43086 passes by the work site with the 1A25 07:00 Swansea to Paddington service.
