Is this _really_ a concern? This sounds crazy to me, how likely are trains to actually collide? Are they not monitored and tracked? Do they not have safety systems?
- tlb 7y agoThey do have signals and safety systems, but things go wrong anyway. Cast your eyes over the last 10 years worth at https://en.wikipedia.org/wiki/List_of_rail_accidents_(2010%E2%80%932019) https://en.wikipedia.org/wiki/List_of_rail_accidents_(2010%E...

- RealityVoid 7y agoAirplanes are not tracked( as in, they run on tracks) so they have more options as to where they might be. With trains it's far far simpler to position. Being on a collision course should be obvious. Funny, I'm form Romania too, and CFR is a shining example of mismanagement. I really doubt we can extrapolate a general rule from what is happening with CFR. Precautions and some automated safety systems could surely avoid this.
- gowld 7y agoTrains are tracked, which means they can't get off a collision course. A plane can turn in 2 directions in each of 2 dimensions.
- antognini 7y agoBART has a safety system that can detect the presence of trains based on the electric potential across the tracks (since the wheels are metal). There was a collision back in the 1970s or 1980s because the repair vehicles had rubber wheels are were therefore not visible to the safety system. A BART train collided with one of the repair vehicles and killed one of the repairmen.
