I must declare an interest. I am prejudiced against wasting £30 billion of public money to shave 33 minutes off the journey time between London and Birmingham but nothing or only a few minutes for other destinations. Travelling to the Continent will require a connection from Euston to St Pancras stations on part of the commuter-standard North London Line .
If £30 billion can be afforded to improve the UK's transport infrastructure then surely reinstating the public transport links that feed into the main networks would make more sense economically, socially and evironmentally. This second and third level network was first cut in the Sixties by Dr Beeching, without a cheaper flexible alternative system to replace it, and now this year with the removal of local authority transport subsidies.
