LNER MD David Horne said: “We are delighted to announce we will be increasing our timetable from February 14, connecting even more customers across our route just in time for Valentine’s Day and half-term school holidays in parts of the country.
“Like many in the transport sector, we have been impacted by staff absence due to COVID and had to make some changes to our services to minimise inconvenience for our customers.
"We are now seeing fewer staff absences and expect that to continue, so we’re looking forward to increasing our services and encouraging more people to discover our destinations and legendary customer experience.”
Also making a comeback are the company's famous freshly cooked full breakfasts and range of hot meals, reintroduced in First Class as on-board catering offer is enhanced.
A wide selection of food and drink is also available as part of Let’s Eat At Your Seat service in Standard, where customers can place their order using a QR code and have snacks served directly to them.
