6024 "King Edward I" stopped at Challow for water from 11:33 to 12:08 and was then on its way again towards Bristol, only to run foul of an apparent signal system failure in the Shrivenham area. A down FGW HST had been standing at the signal in the picture for well over half-an-hour with the "King" at the next signal and another HST behind that. Eventually the HST got the road and has gone on its way and now 6024 is starting away from the previous signal, only to get stopped at this one as well... 12:50, Sunday 12th February 2012.
