East Midlands Trains drivers strike again over pensions
Rail passengers were warned to expect delays as the majority of drivers working for East Midlands Trains went on a new one-day strike.
Driver's union Aslef walked out over plans to reduce pension fund contributions for both workers and the firm from July.
The company said the change would not affect pension benefits but the union said the calculations were unreliable.
Talks are due to take place on Thursday in an effort to resolve the dispute.
Clare McCartney, HR director for East Midlands Trains, said: "We want to meet now to get this unnecessary dispute resolved.
"We share the frustration of our passengers that there will be more unnecessary disruption for people who rely on rail services."
The strike follows two days of industrial action on 1 and 3 May, which resulted in a reduced service.
The union said it represented 460 drivers working for East Midlands Trains, which is about 95% of the drivers employed.
Passengers are being advised to check the East Midlands Trains website for information on services.
