London Midland, who run train services through Leighton, has announced a restructuring plan.
The company says it is facing rising costs and the proposed changes will focus on head office and support staff.
Managing director, Patrick Verwer said: “The service to our passengers will not be affected by the changes. We have made good progress over the last year. Our train service is much improved and higher customer satisfaction scores tell us passengers can see the difference.
“Like every other business however, we have to keep our costs under control. Our proposal has been designed to increase efficiency and reduce our costs while continuing to improve trains and station services.”
London Midland will now begin its consultation with its employees. The proposals will reduce the number of posts in the company by about 150.
