22nd Sep: LNER B1 Class 4-6-0 #61306 'Mayflower' THE CATHEDRALS EXPRESS from Horsham to Bristol Temple Meads 1Z42 Boxhill Westhumble. I did not expect I could catch up with 1Z42 at Dorking because A24 north bound is usually congested at the Dorking Chicken roundabout (today as well). Lucky enough, however, I caught up her at the Boxhill Westhumble station (thanks to running 2 minutes late).
