Virgin Trains is adding 42 services a week between Edinburgh and London from May.
The rail operator will boost seat capacity by 22,000 a week on the route, an increase of almost a third.
Travellers on the service between the two capitals will see four new services daily in each direction, ensuring a half-hour frequency throughout most of the day. Two additional services will be added on Sundays.
UK Rail Minister Claire Perry said: “The UK government knows how important the railways are to keeping Britain connected, which is why we are investing over £38 billion on the network in this parliament. The increase to Scottish services is evidence that this franchise is delivering real improvements for passengers.”
The announcement follows Virgin’s £21 million refurbishment of its fleet, which includes new interiors, leather seats in First Class and carpets and fittings throughout.
Tickets for the new services will go on sale later this week after the Office of Rail and Road (ORR) approved Virgin Trains’ timetable plans.
