I was just thinking of 3 ways to reduce vandalism and was wondering of the
practicality.
1) Link the on Board CCTV cameras to a central control room with controls
such as on train PA use (like Scotrail's remote Announcments)
2) Have another person on the train who can watch the cameras, provide
information and check tickets.
3) Probably not a very good idea, but do as they do in New York and
sometimes in Bristol. Use the older vehicles at night and save the better
ones for the day.


Yes. Not only vandalism, but crime in general, such as handbag
snatching. One of the problems is that CCTV needs people watching it
if arrests are to be made in "real time", rather than as evidence
after the event. I wonder if we could use variations in passenger
noise, eg, sudden screams, impact noises, sudden silences, the kind of
thing that makes us human beings look up. The electronics seem fairly
simple, the vehicle runing noise can be simply allowed for on the
basis of speed. If there was a noisy derailment or gearbox failure,
that would also trigger an alarm - a useful extra.
