The refurbishment includes a new external livery which matches that of the 17 new class 374 e320 trains currently being supplied by Siemens and due to enter service by the end of the year.

The interior of the e300 train has been renewed with a predominately grey colour scheme. A second train has been sent to SNCF's Hellemmes depot near Lille for refurbishment, but no decision has been made on whether any more e300 trains will be refurbished.

Eurostar has also announced a 3% increase in traffic to 2.8 million journeys and a 1.5% increase in revenue to £232m for the second quarter of 2015 compared with same period in 2014. The number of passengers travelling business premier rose by 10% in the second quarter compared with the second quarter of 2014.
