The clockwork orange
..That's the affectionate name Glaswegians give to their subway system, the third oldest in the world. The trains are painted orange and the track goes round in one big circle, a bit like a basic Scalextric set.
People are forever complaining about the service but I get the subway to and from work every day and can count on one hand the number of times I've been delayed.
