If no train on the line moves, sure. But stoping just the one train won't improve safety, and was historically the cause of many accidents. I remember just the one in Shanghai in 201x. One train stopped, the following train hit it.
- taneq 9y agoIf stopping doesn't fix things, you're not using enough of it. Time for networked emergency brakes on all trains!
- Symbiote 9y agoEurope may has that, with the GSM-R system. I remember reading of at least one minor accident that stayed minor because the driver to discover the landslide over the track at low speed passed the button, stopping the incoming faster train on the other track. http://www.szdc.cz/en/pro-media/tiskove-zpravy/funkce-gsm-r-stop.html http://www.szdc.cz/en/pro-media/tiskove-zpravy/funkce-gsm-r-...
- gsnedders 9y agoAFAIK, this is just a Czech extension to GSM-R. That said, I recall various instances of GSM-R being used in the UK to broadcast a general message to stop, albeit one that the driver has to act upon.
- tjohns 9y agoThat shouldn't happen under normal circumstances. That's whole idea behind railway signals. Rail segments (blocks) are supposed to be automatically locked off while a train is on that segment of track. No two trains can be on the same block at the same time. If a train stops, the signal guarding that block will remain red, ordering the next train to stop before it gets anywhere close.
- 7dare 9y agoIn fact, the crash at the origin of this whol debacle was caused by a train being stopped on the tracks and being rear-ended by another.
- jnty 9y agoThat's an interesting way of looking at the cause and effect. Trains unexpectedly stopping in an expected and inevitable property of all networks, whereas trains exceeding their movement authority is not. Stopping a train anywhere should therefore always be safe, so the safety failing is with the train behind, not the one in front.
