I'm 17, and I know a lot of people who are of the younger generation, I don't tend to talk to them that much though. I know a few people who like trains but don't actually come out and say it. I would kid at my school, who knew what the Metro service number would be before it arrived into the station just by checking his watch, I asked him if he wanted to go up to Newcastle one day and his response was 'No, I'm not a trainspotter'. He never mentioned that I liked trains to anyone and he was the only person who actually knew I did.
I almost stopped going out to stations and getting photos/videos because the BTP came over to me and told me I had to leave the station because I wasn't allowed to be there. Since then I know always carry the guidelines on the BTP and Network Rail websites.
Now, I tend to try and just bash places, I've clocked some good mileage this year thanks to ridiculously cheap Advance fares.
I too would love for some things to go up in the world, and it seems to be starting now. Most heritage railways have now got great websites. The Wensleydale Railway has allowed people to book tickets online for their upcoming diesel gala which I think is a great step forward!
An app, would be great. However, what would be on it? Train movements (ECS etc.), integration with 'Real Time Trains', train numbers, integration with a Rail Forum, railtour dates (with possibility to book through the app), and a train ticket booking facility? If people get back to me on what they would want in an app, I would be more than happy to try and put one together (I have part-created an app previously so have a little experience). What devices would people want it on, some people have iPhone (iOS), some have Android, others (like me) have Windows Phone. I have all app stores available as I own devices that operate iOS, and Android and my mobile is a Windows Phone. Would it be better for a separate thread to be opened for this kind of thing? Also, things like cost, I would say a cost of something like £0.69 initial fee then have train movements and train numbers as a possible extra fee, so £1.79 for both, but it would be a yearly subscription. How many would actually want one too though? Especially when such information is available online for free - although WNXX has recently went subscription based - what would need to be so good that people would download it?
We certainly need some sort of innovation to bring it up to speed with the 'real world', but I wouldn't say it will die in 30 years or so. I hardly ever see middle aged men on platforms, but then they are at work so don't have time, once they retire they will have more time to do so.
