Fort Totten Metro Crash Investigation What's Next?
A sight distance test was also performed on Saturday July 18, 2009. This was an effort to examine post-accident rail markings and use them as a means to look at information concerning the striking train. This information would include braking characteristics and speed as derived from the Metro operations control center.
Presumably these phases of the investigation will assist NTSB and Metro in coming up with better back-up systems in case of signal failures in the future.
