Belmond Trains (the operator of the Orient Express) are to run a new luxury sleeper train next year- The Brittanic Explorer with 3 night trips to the Lake District, Cornwall and Wales, all from London Victoria.
The train will be stationary each night.
The Wales route (West Wales and the Cambrian Coast) returns via Moreton in Marsh.
As far as I am concerned having a luxury train come up the Cumbrian Coast to Workington is very exciting. The land excursion from there to Penrith is as much because the train doesn't fit loading gauge restrictions with passengers on board. No doubt that has been orchestrated by a very active Transport Heritage Group who have turned the station into a living Museum.
As you can imagine these trips are not at all cheap, but very interesting.
