Back in the BR days managers used to get quite involved with model railways, and would provide liveries to the manufacturers and use of logos. If you look at film from the 1950s and 1960s, platforms were thronging with enthusiasts with many taking pictures. How times have changed..
The over-zealous application of anti-terrorist laws makes a fool out of the railways. A terrorist would never appear on a platform with a long-lens SLR camera. Most of the information is available on-line, indeed on the National Rail Enquiries site there are plans of all the stations. This is without Google Earth, many published books and guides on and off line.
If anyone did need to go 'on site' they would use concealed cameras or at the very most cameras built into mobile phones, which these days are good enough for HD video. As virtually all of us carry around mobile phones, what's next confiscate all phones from everyone before they board trains? Unlikely, as the railway knows its customers would disappear overnight...
Friends of mine were stopped at Nottingham Trent station recently and were nearly asked to leave the station because a security guard thought they were trying to take pictures of a signal gantry with a cheap consumer camera. Probably ignorant of the fact, you can download a simulator with all the signals on it, quite freely for free.
And what's the chance of getting killed in a Terrorist incident anyway? For the average person next to nill, you have more chance of being run-down walking to the station.
As with all these things, the authorities should be looking at 'risk' rather than introducing draconian laws.
While I quite understand the limitations of photography on private property (although of-course you are quite free to take pictures of anyone you want and upload them to the internet without their permission, or photos of private property from a public place) one advantage of the Nationalised railway was because it was effectively 'publicly owned' station staff were more realistic and friendly to observers as long as they didn't cause a problem.
I puzzle to think what the railways gain from alienating enthusiasts on the privatised railway, who we are told are so-much more 'public friendly' than any nationalised monolithic organisation.
