Ok, i remember now.
Look at the catwalks. They use it when one side has no catwalk, and then it switches over. So say you are going along, no catwalk on the right but theres one on the left. And then the catwalk switches from being on the left to the right, when it switches they put that there so when they do their walk throughs they can safely walk from one side of the track to the other.
I used to think it had alot to do with banking, which, normally it would since extreme banking or banking on hills will lead to a catwalk on just one side, but, thanks to Boulderdash they use alternating catwalks on straight sections because of the rocks or trees or other natural stuff.
So in short, they use it when the catwalks switch sides.
Yeah thats what I thought too. You will also see those boards quite often on hills and on the crests of hills so that the inspectors can get right down in the track safer to inspect the running boards on the steep inclines
