Close
Designed to meet Amtrak's specifications, the Genesis series stands out for being the lowest North American diesel-electric locomotive at 14 feet 4 inches (4.37 m) tall. This allows for easier travel through low-clearance tunnels in the Northeast Corridor, especially compared to the earlier EMD F40PH which was 14 inches (356 mm) taller.
