This one looks as if it has already been patched:
Here is an example of what you get in the middle of every long concrete beam. There is a stress crack, which suggests that the beams are flexing every time a bus goes over them. If water gets into these cracks, and we have hard frosts in the winter, I can see the concrete disintegrating even more:
More patching:
Typical example of flaking of the concrete at a beam end. Presumably this is caused by friction of the guided wheels:
An example disintegration of the vertical surface of the guide 'rail'. Maybe it's cosmetic. Maybe it's more serious:
Flaking of the guide rail:
Shows the disparity in gap widths between the two running tracks:
The gaps on the sweeping curve between Longstanton and Oakington, you could put your hand down there. It really is startling how much they have moved. I just don't see how you can stop that movement now its begun, without taking it up or something.
