Services between Sheffield and Nottingham will be disrupted for one weekend in August to allow upgrades to be carried out at Alfreton Tunnel. Engineers will be renewing the track to make journeys smoother on the 8th and 9th of August. The nature of the work requires buses to replace trains on both days. An amended East Midlands Railway timetable will be in place on the Liverpool Lime Street to Norwich route. Full information on alterations can be found online.
