Don't get over-excited. Our 'photo quiz' is not a competition. We can't afford a prize!

It's all clear on the Down but which remarkable piece of infrastructure will the next train encounter 50 yards ahead of this signal?

In the foreground is an axle counter head, with its yellow connection box in the background. These devices are common on the West Coast Main Line and are now being installed on other routes, much to the anguish of some S&T types.

Nothing metallic must go within 30cm (1 foot) of the head otherwise it thinks it's detected an axle. Clever!
