Update on Caledonian Sleeper Highland service

Published: 26 Jun 2019

Serco Caledonian Sleeper has decided to delay the launch of its new trains on the Highland service, probably until September. This decision will allow the latest set of eight new carriages, which are due to be accepted into service in the next few days, to be diverted to support the Lowland route between London, Glasgow and Edinburgh, which is currently experiencing high levels of demand. This change will improve the reliability and resilience of the Lowland service and will allow us to maintain a slightly higher capacity on the Highland route over the holiday period.

It will also allow CAF, the manufacturer, more time to fulfil their responsibilities and complete the work required on the remaining new carriages to ensure that they can be accepted into service for the Highland route.

Ryan Flaherty, Serco’s Managing Director at Caledonian Sleeper, said: “We are disappointed to be announcing this further delay, but it is undoubtedly the correct decision and will allow us to improve the reliability and resilience of the Lowlander fleet, and maintain capacity on the Highland route. While we are keen to introduce our new trains on the Highland route as soon as we can, our priority must be delivering a reliable service on the Lowland route and then make sure that each new carriage on the Highland route is ready to welcome guests and deliver a true Caledonian Sleeper experience. 

“Our team is working closely with the manufacturers to get the new Highland carriages ready as soon as possible and we are looking forward to launching them on the Highland service once CAF has proved their readiness.”

Guests who have already booked to travel on a Highland service from 7/8 July onwards who still wish to travel and have booked one of our new accommodation options will be refunded the difference in cost; alternatively if they no longer wish to travel they will be offered a full refund or the opportunity to rebook at a later date.
