RTT suggests about half the service reinstated from 3rd Feb, with the rest coming in at end Feb.
Thanks Bald Rick,
I got my info from the National Rail website, but it has now been updated and it doesn't reflect RTT trains info, see below
"A delay to the introduction of new trains has meant that, from the timetable change on 15 December 2019, a number of TransPennine Express services between Liverpool Lime Street and Edinburgh have been temporarily withdrawn from the timetable.
This has affected some departures at the following stations – Liverpool Lime Street, Lea Green, Newton-le-Willows, Manchester Victoria, Stalybridge, Huddersfield, Dewsbury, Leeds, York, Thirsk, Northallerton, Darlington, Durham, Chester-le-Street, Newcastle, Morpeth and Edinburgh.
Over the last few weeks, TransPennine Express have worked hard to help bring in these new trains.
As a result, a number of services will be reintroduced on this route on Monday 3 February, with the remaining services being reintroduced on Monday 17 February."
I am particularly interested in the reintroduction as my wife and I are travelling from Huddersfield to Thurso via TPE to Edinburgh, then Scotrail on 18th Feb. Even if everything works well, we don't arrive until around 22.15 and we have accommodation booked. I am unsure what my options are if the service does not in fact appear!
