47623 Vulcan approaches Circourt Bridge, Denchworth, on 5 July 1985 with what is presumably an ECS working (confirmation anybody?). The same loco and stock were used on the  Cotswold Line Promotion Group's Oxford to Scarborough 'Cotswold - Ouse Special No.3' railtour two days later, but if this is the ECS, quite why it is travelling west is a mystery. No Realtime Trains (or mobile phones) in those days!
