After I had inspected that ground frame (and Joel had screwed tight the cover of the locking bed), I went around the station a little bit. Here are somewhat random pictures from Nene Valley Railway's Wansford station.

Here are a few demonstration pieces of rail fastenings, but also a joint connecting two different types of rail:

The inner starters towards Peterborough are somersault signals—I did not wait for any of them to be cleared:

The gates of the level crossing need locks—here is the rodding of one of them:

And here is a sequence of pictures showing various signal-related parts between the signal box and the advanced starter towards Peterborough:

The brick base of the signal box is not rectangular, but has one corner cut off at the side where a small river flows:

Here are the signal wires and the point (or gate?) rodding leaving the signal box:

On the line to Peterborough, one encounters at first points no.26, where the loop track diverges from the main track. Because trains travel over these points in facing direction, they are heavily interlocked: Not only is there a facing point lock (which, when not engaged, does not allow the home signal levers to be pulled in the interlocking frame), but additionally the lie of the point blades is checked directly by the signal wires:

A bit farther, the points to a storage track have been disconnected from the interlocking and are now clamped. The facing point lock is however still in place:

A bit farther, the rod between the two disconnected points is compensated for temperature changes with this horizontal compensator:

Usually, signal wires are deflected with wheels. The following wire leading to the down advance starter, however, uses a crank that is commonly used for rodding:

The storage area contains a few ground frames—this seems to be common with English heritage railways:

Finally here are the farthest signals I visited:

And that's all from the NVR!
