Water Gypsy
I went back to London yesterday and they must have been working on the line because the train went up to Melton Mowbray, around rutland water and then corby. It took 1hr 10min to get to the next stop which was Kettering.
This route has applied to all Sunday services since the start of February and will apply for the next two Sundays as well. It's been advertised in the timetable since at least last November. The route does not take you around Rutland Water.
