Starting in early October, Metro will turn control of six non-peak Red Line trains over to computers. If all goes well, every Red Line train should be under computer control by March 2015.

This marks the first return to automatic train operation on Metro’s original system since WMATA switched all trains to manual control following the 2009 train crash.

Since then, WMATA has fixed the faulty electric systems responsible for the crash, but only on the Red Line. Fixing the rest of the system will take another three years.

When it works, automatic train operation runs Metrorail more efficiently and smoothly as compared to manual control. That means fewer delays, faster trips, higher passenger capacity, and more comfortable rides.

This is great news to riders who have suffered from motion sickness on manually-driven trains. And it’s an important step forward in Metro’s long, painful rebuilding process.
