Eurostar has begun rolling out newly refurbished trains and it looks like the makeover is on the right track.

One rail expert described the new interiors - on 21-year-old trains - as 'unrecognisable' and declared that 'passengers will think it's a brand new train'.

New features include free WiFi, seatback mirrors and glowing drink holders.

Speaking to MailOnline Travel, Mark Smith, who runs the rail blog The Man In Seat 61, said: 'It's no mere changing of the seat covers - the train has been stripped back to the bare metal and given an entirely new interior.

'Most passengers will think it's a new train - far brighter and lighter than before.

'It also sorts out what's been missing and what people say they want: free WiFi in all classes and power sockets at all seats - indeed, USB points too in first class (previously only cars five and 14 had sockets in standard class).

'And baby changing facilities through the train not just in extreme end cars one and 18. And there are a few interesting touches: illuminated drink holders and seatback vanity mirrors in first.'

Mr Smith, whose website is named after his favourite seat number, 61, on the e300, posted his thoughts on Twitter when he first checked out the refurbished trains back on September 3.

'Internally it's unrecognisable - most passengers will think it's a brand new train,' he wrote. 'Superb job!'

He added: 'Car numbers displayed inside, illuminated seat numbers. Power sockets at all seats. Big step forward.'

He goes on to describe the at-seat USB and power charging points as 'handy,' and that there are a mixture of socket types to suit travellers from different European countries.

Designed by the world-renowned Italian design house Pininfarina, the remodelled trains, part of a £1billion project that includes the introduction of new 200mph trains, have been given the name e300.

The interior colour is predominantly grey and there are now more solo seats in first class.

WiFi 'infotainment' is due to go live later this year, according to Eurostar.

The refurbished e300 now in service will operate to both Brussels and Paris from London.

It will be a rostered service, which means riding in the new-style train will be luck of the draw.

In November last year Eurostar celebrated the 20th anniversary of its services running between London and the continent.

As part of a £1billion project, Eurostar has refurbished a number of its e300 trains

There are many new things too look forward to, but it will be luck of the draw for passengers to end up on one of the new-designed carriages

There were just two trains a day when the service started - there are now between 15 to 17 daily services to Paris.

The original London to Paris journey time when Eurostar started was two hours and 50 minutes.

That was cut to two hours and 35 minutes after the first section of high speed line was built in Kent in 1998, and then two hours and 15 min following completion of the high speed line in 2007.

By the end of next year, travellers will be able to make the 306-mile trip to Paris through the Channel Tunnel in just two hours, thanks to the 200mph trains, called e320s.
