Tata Communications' branded Heathrow Express trains have rolled into service as part of a campaign that will see the company wrap Heathrow Express's entire fleet of trains. Heathrow Express, London's airport train service, carries 17,000 passengers a day between Paddington and Heathrow Airport. With a journey time of 15 minutes, it is the fastest way to get to central London from one of the world's busiest air travel hubs.

Tata Communications will also be using on-board digital screens and TV-spots alongside digital airport panels and cross track advertising to raise awareness of its role as a global connector of businesses  through its global network, cloud enablement and mobility solutions.

Julie Woods-Moss, chief marketing officer, Tata Communications, said, ''For B2B brands like Tata Communications, it can be a challenge to find great brand platforms. The Heathrow Express is a great fit for us. The company seamlessly connects 17,000 business travellers a day between one of the busiest airports in the world and London-one of the greatest cities and a real gateway between the East and the West. The role of Heathrow Express matches our role as a connector of businesses and people globally. We bring cloud, mobile and network services to enterprises across 240 countries, at the highest speed possible.''

Shares of the company declined Rs 2.75, or 0.64%, to trade at Rs 429.10. The total volume of shares traded was 16,678 at the BSE (12.30 p.m., Wednesday).
