Busway damage - even more pictures

Here are some I took today in the Histon area.

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:

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:
