Zip through the French countryside at nearly 300 MPH on the TGV--the fastest locomotive in the world. Ride on the little engines that could as they guide giant ships through the Panama Canal. Watch two locomotives crash head-on as the federal government monitors safety. Descend 700 feet below the earth's surface where mining locomotives move miners through a maze of tunnels. Then, it's a "jiffy lube" for locomotives inside America's largest maintenance shop. Finally, glide into the future with a locomotive that levitates on a cushion of air.
