East Midlands Trains sees sixth strike day
The last of six one day strikes by drivers on East Midlands Trains (EMT) has begun.
Union Aslef called the industrial action in a dispute about plans by the firm to cut contributions to its pension fund.
Talks between the two sides last week ended without agreement and another union, the RMT, has said it will hold its own strike ballot.
No new dates for industrial action have yet been announced.
EMT has insisted the strikes are unnecessary as staff pension benefits would be unaffected.
But Aslef has disputed the calculations and said the company has not entered into meaningful negotiations.
EMT said it would work to keep disruption to a minimum but passengers are advised to check its website before travelling.
