Rob is correct here. You dont know the first thing about what is going on with the railroad. When you think of the US railroads in the same way the UK operates you are simply wrong. There is a lot more area here, a lot more rail network, and a lot bigger trains. This isn't the first time you have shown up to a thread and applied your "knowledge" to form an opinion without knowing the slightest thing about or completely ignoring the circumstances. A mistake was made and people died for it. Have some respect for them instead of spouting off about "systemic failure" when you know nothing.
^^Nailed it
It would be wise if everyone refrained from turning this place into TrainOrders and freaking out over an accident where two men lost their lives in a horiffic manner.
That being said, it is not fair that US railroads are compared to UK railroads. The US rail system was build primarily for freight after the 1950s and 60s when the automobile and aircraft captured the American spirit. Passenger rail, despite being around again for 40ish years, is now on a comeback thanks to a generation that takes the train more. That is why Amtrak's ridership has increased year after year. Additionally, PTC is still a relatively new technology here and it will take some time to work out the bugs and adapt it. The PTC system in use here (ITCS) still goes down from time to time because it is not a perfected system yet. However, when it is up, it does its job well and as a result we have some of the fastest trains in the country clocked at 110 MPH with 125 MPH-capable equipment coming soon.
To recap: Stop comparing the US to the UK. Both rail systems are great at what they do, but they were built for different purposes. Also, passenger rail is making a comeback here and it will take some time for the rail network to be adapted completely to account for the safety factor.
