... end of the slip leads to another diamond. But before it there's a check rail on the outer rail of the curve. It is clearly not part of the diamond's own check rail. Hi Derek, The check rail looks to be the remains of a V-crossing leading to a spur which has been plain-lined at some stage (replaced with plain rail on the same timbers). You can see the remains of the vee splice rail in the bottom-left of the picture.
