Is this a record?

I've not seen one of these in Oban before. We went up to Pulpit Hill briefly after going to the shops this morning, just to see if there was anything worth photographing and spotted this train. Our route home took us alongside the railway so I jumped out to get a picture.

'Track recording train', eh? Wouldn't have thought that you needed a train to record your latest album! Behind the train is the ferry terminal.
