Scotrail train of the day

I was already late for the pub and was going to give this train a miss. I have loads of train pictures anyway. But the woman driver gave an insistant hoot, so I pointed my camera. She slowed down for me like she did the last time. I thought I'd better give her a wave, so I did. She then waved back enthuastically. When people are nice to you for no obvious reason, it makes an impression.
