"From 25 June we will start to run an overnight service again on Thursdays and Fridays only, in both directions.
For the first three weeks we won’t be selling cabins, just seats.
After this, we plan to increase the frequency, and start offering cabins, on a gradual basis.
When customers arrive, they will see that the train includes a sleeper carriage and the café. These won’t be used but are there to help keep colleagues up to date with their training. We recommend that you bring drinks and snacks with you.
Services will show in online journey planners as an overnight train, rather than a sleeper."
