43177 speeds past Circourt Bridge, Denchworth on 16 October 2012 with the 1B37 13:15 Paddington to Cardiff Central First Great Western service. 66149 can be seen approaching along the relief line with the 4D12 13:22 Didcot Power Station to Avonmouth coal empties. It would appear from this picture that I would be taking the picture of 66149 a few seconds after the HST had passed. However, such was the coal train's incredibly slow speed that it was a full two minutes before it reached this spot!
