Sir, – Paul O’Shea’s letter challenging David Traynor’s suggestion for a high-speed rail spine makes great sense (“A high-speed rail line,” Letters, March 18th). He points to the fact other European countries rely on low-carbon generation and nuclear power to support high-speed rail. As Micheál Martin casually told the Dáil recently, the loss of even one undersea energy connection would close down the country. We need to re-evaluate the effectiveness of our climate policy as it has been rolled out to date. Is transport policy working?
