Ended up at Bewdley all 3 days, seems like 4566, 7812 & 43106 were working the services each day, although I didn’t see the 3 locos every day.
Today was a bit of a hard slog, getting to Bewdley by public transport (on my own, fortunately) as there were delays on London Midland trains. Trains at Old Hill are every 30 minutes, but more stop at Cradley, so that was where I headed. At Cradley it was apparent there were still problems, one train was over 30 minutes late, and eventually cancelled, and others were delayed, but I managed to get to Stourbridge for the “Dodger”. Then the bus to Bewdley was late, and delayed even further by roadworks near Kidderminster. The SVR train had already departed by the time the bus approached Kidderminster station, so I had to stay on to Bewdley, arriving there about 20 minutes late. At least there was time for lunch before catching 4566 back to Kidderminster, then bus, dodger, train & bus home. It’s so much easier by car!!!
