The article quotes AAR spokesman Ed Greenburg as "We have been warning for years that the deadline was unworkable because the technology had to be developed from scratch."
Why does such technology need to be developed from scratch? Positive Train Control sounds very similar to the in-cab signalling schemes (European Train Control System) in use in Europe on the Eurostar and other high-speed lines, and is continuing to roll out on other lines, would adapting that technology not make a good start?
- ant6n 11y agoIt seems most of the world is moving towards ERTMS. The 'not-invented-here' syndrome is strong in the US. But there may also be compatibility issues, in the US they have a completely different view of railroad safety (laregly boils down to 'if there's an accident, our trains should be built like tanks so it doesn't matter' vs 'there should never be railroad accidents'). That's one of the reasons why there is very little transit on main lines.
