Commuters and other rail users travelling to and from Leicestershire stations will be offered reduced fares and compensation during major summer works.
East Midlands Trains warn passengers travelling north to Nottingham to expect disruption to services from Saturday, July 20 through to Sunday, August 25.
A £100 million project by Network Rail to re-lay tracks and overhaul signalling in Nottingham means all mainline services to the city will terminate at East Midlands Parkway, near East Midlands Airport.
Buses will be laid on every 10 minutes for passengers to complete their journey.
It also means passengers returning south from the city – to Loughborough, Leicester and Market Harborough – will have to catch a bus to East Midlands Parkway before resuming their journey by train.
Holidaymakers from Leicestershire travelling to Skegness, meanwhile, will have to get a bus from East Midlands Parkway to Grantham for their onward journey.
East Midlands Trains, which is part of the Stagecoach Group, said has said it will offer a 15 per cent discount on fares for travellers affected by the disruption.
"We have worked hard with Network Rail to ensure that we can continue running trains wherever possible," said customer service and commercial director Neil Micklethwaite.
"However, we know that many customers will face disruption to their journey and will need to use replacement bus services for parts or even all of their journey during the works."
Commuter Peter Reeve, who regularly travels between Nottingham and Leicester, is not impressed.
"I don't know why I bother paying for a monthly season ticket when there are no trains running," he said. "I reckon most commuters will be furious when they find out what's going to happen."
Justin Page, acting route managing director for Network Rail, said: "We're spending £100million to completely rebuild the railway through Nottingham.
"We're using modern equipment to replace 1960s style signalling, putting in a new platform and relaying six miles of track."
He added: "There will inevitably be some short term disruption during an investment of this scale and I sincerely apologise for any inconvenience that this will cause."
East Midlands Trains said customers already holding an annual season ticket for travel on affected routes will also receive two weeks worth of free travel.
Mr Micklethwaite added: "We it was particularly important to do something unique for our customers to recognise the major change they will see to their normal train journey.
"It's the first time a train operator has ever provided compensation and discounts for customers during a major period of work such."
Local train services will run hourly between Leicester and Loughborough, calling at Syston, Sileby, Barrow-on-Soar, but the Loughborough to Nottingham service will terminate at Beeston.
