Perhaps obsessive behaviour is more readily tolerated in the UK? In other developed countries, it would be seen as a sign of mental illness that needed treatment. ;-)
That must have been fun! I was an adult before I got on the footplate of a locomotive that was in steam. But from about 14 onwards, I was a regular visitor to signalboxes and began taking photos of trains.
Good to hear that. Is the average age getting older? Is there a market in NZ ready-to-run trains? I ask because the narrow gauge must complicate things somewhat.
