The Phantom Express (1932)

An engineer at the throttle of a locomotive speeding through a tunnel sees the lights of a train approaching from the other end. Although the signals say the track is clear, he still sees the train's lights. He grinds the train to a halt, derailing it. He survives, but many passengers are killed. He is fired in disgrace, but sets out to prove his innocence by finding the "The Phantom Express".
