The sun rises out of the north sea as we leave Arbroath. And then we are into a bank of rain. We slip in and out of it as we head across country. Everchanging lines of geese head south, crossing our mainly-west route. At each stop i breathe in the fresh air wafting through the open door behind me. Slim chance of acclimatising, but it helps me wake up. The train journey will be over in about an hour, and then my feet take over.
