Gary Walsh, Route Director for Network Rail’s East Midlands Route, said: “Over the Bank Holiday weekend, Network Rail teams will be out working to improve reliability on the Midland Main Line, something which is particularly important during the Covid-19 crisis as critical workers, such as doctors, nurses and supermarket workers, as well as freight services transporting medical and food supplies, rely on the railway.
“We strongly advise those who need to travel over the Bank Holiday weekend to check before travelling via National Rail Enquiries or with their train operator and we would like to thank people for following the Government’s advice on public transport use.
Please continue to avoid public transport where possible, and where you do have to use it, follow the guidance on social distancing and allow more time for your journey.”
Lisa Angus, Transition and Projects Director for East Midlands Railway, said: “We are advising any passengers who may need to travel on the Midland Main Line over the Bank Holiday weekend to check our website as there are a number of changes to our services that may affect your journey.
Jenny Saunders, Customer Services Director for Thameslink and Great Northern, said: “We thank our passengers who need to travel over the weekend for their patience while Network Rail carry out this vital track renewal, which will help improve the reliability of services.
“There will be no Thameslink services between Mill Hill Broadway and St Pancras, where a replacement bus service will run, and a reduced service on many Thameslink routes for various periods over the three-day weekend.
“Please follow the government advice to travel only if absolutely necessary, and to avoid public transport if at all possible. If you really have to use a train or bus, it is important to check routes and times before you set off, follow social distancing guidance and wear a face covering if you can.”
