Although a not a full-on Thomas the Tank Engine fan, I have for 65 years been an out-there and unashamed enthusiast for anything running on rails (‘Thomas the Tank Engine clung to me like a disease’: the film about the choo-choo’s global grownup superfans, 22 July).
My wife and I sometimes do front-of-house at a heritage railway and can confirm the attraction of railways for those with autism, particularly young people. There is a predictability about railways, timetables, signals and all the other paraphernalia that is very attractive.
