YORK rail giant GNER is involved in plans to design a new High Speed Train (HST) capable of running on diesel power or electricity.

The new train, which could be in service within the next decade, would replace the current sets used on the East Coast Main Line.

Although design work has not yet begun, rail industry sources claim that some early research and development is already under way.

It is understood that any new HST could probably run as a diesel train, but also have the ability to use an electric power source.

For GNER, it would give the York-based company the chance to use HSTs across the country.

The company operates Class 91 electric trains on the East Coast Main Line, but its current HST sets, with Class 43 diesel power cars at both ends, are more than 30 years old. The company's franchise is due to run until 2005, and it is looking to open negotiations with the Strategic Rail Authority (SRA) about an extension to its current operation.

If talks are successful, GNER would be able to get on with any work and consultation regarding the new train.

GNER is also pressing ahead with plans to apply for other franchises on the rail network, necessitating the need for new and adaptable train sets.

Other train operating companies, including First Great Western and Midland Mainline, may also be involved in the new HST concept.

The SRA is understood to be said to be keen on the concept of a new HST.

Christopher Garnett, chief executive of GNER, said: "We can't go on endlessly improving HSTs - we need new trains."

GNER company spokesman Dave Mallender added: "The existing trains have done well but in time need to be replaced.

"It makes sense to have a train that would have the ability to run on different routes. We know there is a need for high speed diesel trains in the future.

"There is a requirement for this kind of train, if we are able to get our franchise extended beyond 2005.

"Other operators will see the same, so let's work together to find a common solution."
