Answers on a postcard

So I am not sure what this guy was doing in the station but it kept me interested in what ever it was until my train came.

I figure I will see more of it tomorrow, but it seems to have something to do with various cities around Scotland

While it does not look all that impressive, the chap in the picture was free handing the whole thing at quite some pace.

Anyway answers on a postcard if you know what it is for.......
