A closer study of a pair of the lower quadrant signals controlled by this box. Each has a letter M superimposed on the arm, and a mechanical route indicator to show the choice of routes ahead. What may appear to be a miniature arm on the left-hand post is actually another signal in the background.

There's some quaint rolling-stock to be seen in the sidings.
