A think-tank said in a report out today the demand for the HS2 link - which will connect Leeds to London - has been "overestimated".
"Demand for HS2 has likely been overestimated by oversimplified government modelling.
The foundation suggested alternatives for the money that will be spent on HS2: £10 billion could transform rail infrastructure in northern England and the Midlands, creating new and faster east-west rail links, redeveloping stations and electrifying regional rail lines
"It could overhaul the East and West Coast main lines, increasing the speed, capacity and reliability of north-south rail travel with less environmental damage than HS2."
"HS2 is the largest transport investment in the UK's history. At the moment it amounts to a £33 billion gamble.
"Our research shows the Government is backing the wrong horse. Instead of pouring billions of pounds into a single line that will take 20 years to complete we should be spreading our bets on a wider range of transport investments that offer better value for money."
