What's with WMATA train operators? First the train accelerates then slows down, the accelerates again, causing discomfort for riders. Second, why the hard braking? WMATA operators need to know how to operate the trains correctly and keep in mind passenger safety and comfort.

Train operators operating in manual mode respond less smoothly to lose of speed commands then does the train board automatic train control system.

When operating in manual mode operators are required to move the controller handle from one of the 5 power position to brake 3 or greater within 5 seconds of loss of speed commands or the train will automatically apply emergency breaking. When the speed commands are reacquired the train operator can move the controller handle back to a power position.
