It’s probably no coincidence that railway preservation in GB coincided with unparalleled levels of prosperity - Macmillan and ‘let’s face it, most of our people have never had it so good’ etc etc. That epoch is now gone. In the USA, for instance, the amount of disposable income spent on essential services has now jumped from 27% to 37% (slightly puzzled on relationship between ‘disposable’ and ‘essential’ but I get the point). The generations growing up now in all likelihood will not have the time or money for this kind of stuff in the way that the postwar generation did. I suspect the UK preservation movement is going to hit a demographic and financial cliff edge. Fact is - and it is fact - most preservation volunteers here are 50 plus males. I am now the age at which my dad retired - I can’t even begin to think of that, and fully expect to be working up to 70. Wealth disparity in the developed world is growing - more money concentrated in fewer hands - and the cohort of people with time and money for things like steam railways is shrinking . And that’s in a country which actually loves the things.
