However detached from everyday events, I am continually astounded by accounts of disaster at crossing, like "Officials: 40 passengers injured in NC truck-train collision" March 10. Hey you Science Fellas, in a day and age when we routinely send rockets to distant planets.....
...as a ham radio operator 74 years ago I could have described a perfectly feasible system to detect a large metallic object at a crossing, then send out a signal that would reach the train in time for it to safely stop. It's called "radio."
Of course it woulda used tubes so cost a bit more to build. But didn't they have any such accidents back then?
It sounds like you don't know anything about train stopping distances.
@contrex,
No, Con, but I do know something about the range of a radio signal
Even if the meeting cojuld be a
little less violent
You clearly don't understand very much about railroad operations.
Your typical grade crossing accident involves a road vehicle being in the way of a train because the road vehicle driver ignored the flashing red lights which are triggered by the approach of a train. The lights are triggered when the train is too close to the crossing to stop before reaching it. Railroad operators are reluctant to run all their trains at 15 mph just because a few dumb car or truck drivers decide to take a gamble. Also the obstruction detector might give a warning that was obsolete by the time a train arrived and stopped. Many grade crossings have a telephone number displayed where people can alert the railroad controllers to a blockage.
Of course, there might be other reasons for the vehicle being on the track, like the driver is confused or does not read the signs and if they get struck it could be said to be just bad luck. Often there is a line of cars stopped beyond the crossing and as more vehicles arrive the line backs up across the railroad track and a gap is not left for a train to pass, then when a train approaches one car is trapped. I have seen a video taken by CCTV where a semi trailer rig is stopped over the tracks, the drivers tractor cab is past the track but the trailer is not, a freight train ran into the trailer and tore it apart like it was a cereal box and the tractor cab spun around very violently.
Accidents are declining in the US, but of course, the best thing would be to remove grade crossings, and in the United Kingdom, where we have passenger trains going at up to 125 mph, and 1000 ton freight trains doing 60 mph, they are being removed wherever possible.
@contrex,
Thank for that, Con. Well, in my own defense I did suggest that if brakes could be applied just a
little earlier it might not do
quite so much damage

But Con isn't that preferable to killing a few humanoids
Besides doesn't my position hold for vehicle that gets stuck long before the gates come down, where did I go wrong

If the vehicle gets stuck the driver can call the railroad or failing that the police who can radio or call the railroad controllers. In the UK these crossings have telephones linked directly to the signal cabins so trains can be halted.
I guess it comes down to balancing the number of lives potentially saved against the cost of the measures and their impact on railroad operations and profitability. If a railroad needs to run 100 trains a day along a particular line to make a profit, and your radio collision preventer reduces the number they can run to 50, they will close the line.

But what if he doesn't have a phone or if he does, can't find the number in time
Quote:or failing that the police who can radio or call the railroad controllers.
By which time of course…..

So why haven't we so emulated 'em decades ago

Alas

But in a day and age when sending men to the moon got so easy we quit doing it…………..
@dalehileman,
Dale, maybe you should write your congressman!

Thanks once more, Con, but at 84 I'm laziness personified. Apple Valley, Ca; gimmy a link to him and I'll send him a link to this thread
I was being sarcastic, because your idea is about as practical as stopping people from drowning by paving over the ocean.
@contrex,
But Con, forgive me but you're not convincing. It's a fine idea and should be pursued
Hitler indeed made fun of Einstein
Again my apologies Con, couldn't resist
if it was such a good idea, don't you think it would have been done already?

But if it saves just one life, it's worth whatever it takes - isn't it?

Not if it affects even slightly the corporate budget
