Are you a frequent rail traveller from Totnes to Taunton? Satisfied with the experience? If not, you can now complain (via email) to none other than Roger Porkess, chief executive of Mathematics in Education and Industry. Mr Porkess spends so much time travelling between home (Totnes), MEI (near Westbury in Wiltshire) and meetings in London that he has joined a new customer panel set up by First Great Western to strengthen the consumer voice. "It's in my own interest to make the service as good as it can be," he tells the Diary from the Westbury platform, where his train is seven minutes late. Most piquant complaint so far? The hideous lime-green upholstery used in a trial coach that had video screens on the seat backs.
