Five new high-speed rail lines could be introduced in the UK to help cope with rising passenger demand for train travel .
Network Rail is expected to announce today its plans to commission a study into what could be the largest track build since the 19th century, as part of a review of the UK rail network .
The study will consider laying new lines, which will cross the length and breadth of the UK, alongside five of the busiest routes, including the East Coast main line and West Coast main line, by 2025.
The company said it would be looking at five routes north and west of London - Chiltern, East Coast, West Coast, Great Western and Midland Main Line.
UK passenger numbers have soared by 40 per cent during the last decade, with 1.13 billion journeys now being taken per year. In addition, numbers are expected to grow by a further 30 per cent in the next 10 years according to rail officials.
A spokesman for Network Rail said: "We are looking at these five strategic routes. We are possibly looking at new lines. There is a huge case to be made for an expansion of the rail network ."
Transport campaigner Richard Dyer commented: "Expanding Britain's railways by building new high speed lines is potentially very exciting - and could play an important role in weaning Britain off fossil fuels and developing a low carbon economy .
"But the overall impact that this would have on local people and the environment must be carefully considered.
He added: "The UK needs a modern, comprehensive and affordable rail network to provide a real alternative to cars, lorries and short haul flights, and help cut Britain's contribution to global climate change .
"Our creaking railway system desperately requires huge investment to bring it into the 21st century.
Ashwin Kumar, passenger director of independent watchdog for rail users Passenger Focus, also welcomed the review and stressed the importance for the "rail industry to anticipate future growth".
