Furious travellers have criticised train staff for going on strike.
Engineering and maintenance workers at East Midlands Trains have downed tools over a pay dispute.
The industrial action by members of the Unite Union started on Sunday, July 27 and will continue until 5.59am on Thursday.
Those waiting for replacement buses at Nottingham Station yesterday morning said they felt let down.
The union is calling for the company to improve a 2.75 per cent pay offer for the year ending April 2015, claiming other employees have received more.
Roy Chambers, of Giltbrook, was trying to find the replacement bus to Ipswich.
He said: "I can see their point, but it is doing no good at all. Striking for five days in a row is too much.
"I don't think there was enough notice given and my journey is going to take twice as long."
And commuter Vicky May, of Dronfield, said: "I was supposed to change here for a bus to Peterborough.
"I know there is not a lot the staff can do, but they keep giving conflicting advice which doesn't help.
"I am going to be at least two hours late. I am coming back on Wednesday and I just hope it will be better then.
"The only people they are inconveniencing is members of the public. I am furious about it all."
Until Thursday morning, buses will replace trains on the Robin Hood Line to Mansfield and Worksop and the Nottingham to Newark and Lincoln routes.
Passengers travelling on the Nottingham to Derby and Matlock route will have to get on a bus from Derby to continue their journey.
Commuters going to and from Grantham, Peterborough and Norwich may all need to change trains at Nottingham.
The majority of services will continue to run as normal to and from London, although a number of services may operate with fewer carriages.
A spokesman from East Midlands Trains said: "We are sorry to hear that some of our passengers were frustrated – we share their frustration over the unnecessary action being taken by Unite.
"We have carried out a comprehensive communications campaign over several days to inform our customers of the changes to their service and this will continue until the action comes to an end.
"We have extra staff at Nottingham station to assist passengers and this morning we also arranged a number of taxis in addition to our replacement buses to ensure passengers got to their onward destination."
"We do take all passenger feedback on board and will work to provide the best possible service during this action."
Unite declined to comment.
