We don’t hear enough about Network Rail these days. By that I mean that the entity recently described by the Sunday Times as ‘synonymous with incompetence and delays’ doesn’t receive anything like the abuse it deserves for failing to provide the infrastructure essential for a 21st-century railway. I refer you to the Crossrail project, in which the inability of new trains to connect with old Network Rail signalling systems is one reason for the delayed opening that has become a major national embarrassment.
