A short irregular diamond fitted with movable K-crossings (switch-diamond) because of the sharp curve, even though the angle is quite short. Also mechanically worked and with facing-point locks both ways -- making a nice collection of rods and cranks:

Thanks to John Woolley.

What are the flat strips just outside the rails in the six foot on each side of the diamond?

Jim.

They are stiffeners attached to the ends of the timbers, to prevent the timbers moving apart or closing up.

It is important that the K-crossing wing rail knuckles don't move out of alignment with the moving point rails.

In a fixed K-crossing they are all bolted solid with spacer blocks, but obviously that's not possible with moving point rails.

In an ordinary switch, switch anchors do the job of keeping the moving point rails aligned with the stock rails. Because of the much steeper switch angles in a switch-diamond, such anchors would not be feasible.

regards,

Martin.

Interesting photograph. What's the purpose of enclosures adjacent and at right angles to the K crossing? Electrical detection?
