Heathrow Express has announced a substantial rebranding, which will be in place before the summer Olympics.

The high-speed service, which expects to be an integral part of the Olympic transport operation, is spending £16 million on its new brand which includes refurbished train carriages and new staff uniforms. The ticket offices at Heathrow and Paddington will also be revamped in the new corporate colours.

The enhanced train interiors in First Class have been designed by Tangerine, which was the company behind British Airways’ first flat-bed seat.

Keith Greenfield, Heathrow Express’ managing director, said: “There will be individual seats for privacy in First Class – they will be larger and more comfortable.

“In Express Class, we will be offering passengers the ability to download, email and recharge their portable devices. We will also be offering widescreen TVs offering flight departure and airport information.

“The changes will take place as London prepares to welcome the world for the Olympic Games

“As London takes centre stage in 2012 we are proud to be the front door to the city and will be ready to host our spectators, supporters and the world’s media on Heathrow Express..”

The roll-out will be introduced in stages with the new train due to be unveiled on April 26 and staff will begin wearing the company’s new uniforms in July.
