A power failure led to East Midlands Trains services being cancelled this morning (Monday), affecting a series of travel-to-work London trains.
The power problem led to a complete loss of signalling between Wigston and Market Harborough.
Network Rail said at 9.30am today that they had now isolated the problem, but they were unable to say when normal services would be resumed.
Passengers arriving at Market Harborough station this morning were met by station staff who warned them of the delays and advised that a replacement bus service would start up from around 8.30am.
The replacement bus service was running between Leicester and Kettering, stopping at Market Harborough.
Passengers making short journeys were advised to go by car where possible.
Some trains were being diverted and were not stopping at Market Harborough. Today’s timetables showed all morning trains cancelled up until the 11.46am train south.
But the situation was still fluid, with no time for repairs to be completed yet given by Network Rail.
