There currently is one option to travel by night train from Penzance (United Kingdom) to London (United Kingdom), taking between approximately 7 and 8 hours: Namely the Night Riviera Sleeper EB operated by Great Western Railway.
Great Western Railway (GWR) operates the Night Riviera, a sleeper train running six days a week between London Paddington and Penzance.
The Night Riviera offers airline-style seats and cabins. Seats are complimentary and can be booked like a regular ticket. Cabins require a separate reservation and are popular, so early booking is recommended. Cabin guests enjoy complimentary light breakfast on board.
Sleeper cabins come in two types: single cabins for one person and twin cabins for two people. All cabins are comfortably equipped with a sink with tabletop and waste bin, UK plug sockets and USB points, a wardrobe, and storage space under the bottom bunk. The bottom bunk converts into a sofa for daytime relaxation. Complimentary light breakfast is delivered to your cabin.
Only cabin passengers can use the shower facilities at Paddington, Penzance and Truro.
Cats, dogs and other pets can join you on board – up to two per cabin. A cleaning fee is charged per cabin. Dogs require an appropriate lead and other pets need a rigid carrier. Pets must stay on the cabin floor, not on beds, and should not be taken into corridors or lounges.
