Also you might want to consider how aircraft manufacturers manage. You
think Boeing or Airbus are going to say to BA or Virgin "Sorry lads,
but we can't get the parts for the avionics or engine control system
any more, you're going to have to scrap that 20 year old $100million
747/A340". Of course not.

I can see the problem but not how they answered it. It won't be cheap,
that's for sure.

I'm pretty sure its all modular so you can unplug an old module and plug
in a new one with exactly the same I/O ports and protocols but whatever
is inside may be completely new. I find it hard to believe that something
isn't done on trains to allow them to be kept going after the original
electronics components are no longer available.

It might be done that way now but we're talking about technologies
implemented 30 years ago.
