I don’t claim to be an expert in construction project management, or indeed public transport, but to attempt to compare the state of the railways with construction, as Paul Morrell does (3 September, page 40), is surely wrong. Railways provide a service to the clients – the passengers – who have no say on issues such as the timetable or performance. But as experiences at Holyrood have taught us, the clients in the construction industry can have a dramatic effect on key issues.
