"AVANTI West Coast has been unveiled as the name of the operator replacing Virgin Trains.
Aberdeen-based
transport company FirstGroup and Italian firm Trenitalia announced the brand name for their partnership which will run services on the west coast route from December 8.
Their trains and station signs will display an orange triangle logo symbolising the 400-mile train network which links London with towns and cities across
Scotland, England and North Wales.
Avanti West Coast is pledging to deliver a range of passenger enhancements, including 263 more weekly services by 2022.
The existing 56 Pendolino trains will be completely refurbished with 25,000 new seats, more reliable wifi and improved catering.
“We are thrilled that the name Avanti has been chosen to represent these values to our customers and pays tribute to our expertise in transforming Italian railways.”
