DERAILED: Despite a rash of deadly train crashes, the railroad industry's allies in Congress are trying to push back the deadline for installing technology to prevent the most catastrophic types of collisions until at least 2020, half a century after accident investigators first called for such safety measures.
DETOURED: Four senators with industry ties recently introduced a bill to extend the deadline another five to seven years. Under a law enacted in 2008, the systems are supposed to be running by Dec. 31, 2015. Only a handful of railroads are expected to meet that deadline.
DEBACLE: The National Transportation Safety Board has investigated 27 train crashes that took 63 lives, injured nearly 1,200 and caused millions of dollars in damage over the past decade. Officials say they could have been prevented had the safety system been in place. The NTSB first recommended advanced train control systems in 1970.
