Technology for its own sake?
--- "Dave Liney" wrote: Just use that information to decide whether or not to open the doors at each station. Problem solved. Until a security alert closes a station so the train doesn't stop there and then the count is off by one. So how does it keep the count of "The next station is..." displays updated when that happens? Presumably the driver just presses a button (or a touch-screen display or whatever) to update the count and let it know the train's not stopping. Or maybe the signal box does it by remote control. Or something. The details don't matter. The important thing is that there already has to be some way of keeping the station count updated even when GPS isn't working. So why not use that for the doors as well? |
