68011 emerges from Brill Tunnel in the rain on 14 January 2023 with the 1R24 11:00 Marylebone to Birmingham Moor Street Chiltern Railways service. Although I have taken pictures at the southern end of Brill Tunnel, this is the first time that I have visited the north end. Apart from a few days in high summer, this location requires a dull day for a decent picture, and this day was certainly dull!
