Train operator Northern said a new timetable will come into effect from Sunday, May 15 to 'deliver better reliability' and 'punctuality' for customers.
The affected services are from Leeds to Nottingham via Sheffield and from Leeds to Sheffield via Dearne.
However, on the majority of routes, Northern will maintain service levels established in December 2021 and some routes will see increased seat capacity and service uplifts.
Tricia Williams, chief operating officer at Northern, said: “Customers are at the heart of everything we do, and the new timetables are designed to deliver high levels of reliability.
“We’ve made decisions about our timetables based on the levels of resource we have available and prioritising the routes with the highest customer demand, and which support the region’s economic growth.”
She added: “We fully understand the role we play in keeping people on the move and I am asking our customers to familiarise themselves with the new timetables ahead of the changes this Sunday, and to check carefully before any journeys to ensure their journeys go as smoothly as possible.”
