A pretty special assignment - taking photos of the rising sun from within Box Tunnel on the London-Bristol mainline. The tunnel was designed by Brunel, completed in 1841, and legend has it that the sun shines all the way through the 1.83 mile tunnel on his birthday (April 9th). I joined an expedition organised by GWR to see first hand if that is true.
Results were inconclusive,: the sun certainly aligns with the tunnel, and if it wasn't for the light mist it may have shone all the way through. Some of these photos appeared in the Telegraph and The Guardian the next day.
