Gbrf class No. 73213 leads classmate 73-207 south through Bowes park station on the Hertford loop while working from Peterorough to Tonbridge on29th July 2010. This may have been a first for these locos on the Hertford loop.

Supposed to stop at Potters Bar to pick up punters but not likely due to engineering works, one wonders if they will pick up at Hertford as a alternative or just use Stevenage.
