I highly suspect that this will be further reduced so please check again if making essential journies. If not making essential journies then stay at home.
Sunday 14th June 2020
TPE trains will not stop at Meadowhall. Passengers for Meadowhall are advised to change at Sheffield Midland for Northern services towards Barnsley or the Supertram. An additional fare is payable for the latter.
On Wednesday 25th March 2020, the Rail Delivery Group added the following temporary easement to the National Routeing Guide:
" 700908 (Map) During engineering works on 22/03/2020 and 29/03/2020, customers travelling from Cleethorpes, Grimsby or Scunthorpe to Manchester or Manchester Airport may travel using Services between Sheffield and Huddesfield. This easement applies in both directions."
As predicted, TPE have issued a replacement timetable for Sunday 29th March 2019. It is linked below
