[quote]QUOTE: Originally posted by retsignalmtr the railroads don't want to spend the money to install positive train control technology. with it even if the train crew missed a red signal the train would stiil be brought to a safe stop. there is a very simple mechanical device called an automatic train stop that is wired in with the signal. when a signal is red it raises a mechanical arm 2 1/2" above the rail outside of the rail and engages a brake valve on a locomotive causing the brakes to go into emergency. this would stop trains from running out of sidings and hitting other trains from the rear or head on. [/quote] At least one Railroad is willing to spend the money: NORFOLK SOUTHERN, the best in safety.
