there are no trains showing for the whole of the 2nd on east and west coast lines, including Lewes to HH. showing 4 trains an hour up and down BML to HH, we know there are works at London Vic which would probably reduce the number of trains.
i'm inclined to think its the software. as i recall it shows the timetabled departures with note to expect delays and bus replacement when there's a line closure. if there's no engineering works, why else would there be no trains? a secret strike?
