GE Genesis
The GE Genesis (officially trademarked GENESIS) is a series of passenger diesel locomotives built by GE Transportation for Amtrak, Metro-North, and Via Rail between 1992 and 2001. A total of 321 units were produced.
Designed to meet Amtrak's specifications, the Genesis series is 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.
The GE Genesis series stands out for its unique, lightweight monocoque carbody design, styled by industrial designer Cesar Vergara. This innovative approach translates to improved aerodynamics and fuel efficiency compared to its predecessors. However, the complexity of the monocoque design results in slightly higher maintenance and repair costs. Notably, Amtrak equips its Genesis locomotives with bolt-on nose cones to facilitate rapid repairs in the event of a grade crossing collision.[citation needed]
The Genesis represents a significant leap forward in performance. It boasts a 22% improvement in fuel efficiency and delivers 25% more power compared to the F40PH. Furthermore, all Genesis locomotives utilize modern, four-stroke engines, surpassing the two-stroke technology employed in earlier EMD counterparts.[citation needed]
Further enhancing reliability, the Genesis is a fully computerized locomotive. Its onboard computer systems automatically manage various functions, including real-time adjustments to engine output in response to overheating, low oil pressure, or reduced airflow intake. This ensures continued operation during minor operational deviations, streamlining maintenance requirements.
All Genesis locomotives provide head-end power (HEP) to the train via an alternator or inverter powered by the main engine. This system delivers a maximum output of 800 kilowatts (1,100 hp), capable of powering up to 16 Superliner railcars. The P40DC and P42DC models offer two HEP configurations: normal mode with the engine speed locked at 900 rpm for providing both HEP and traction power, and standby mode with the engine speed locked at 720 rpm for HEP only (no traction power). The P32AC-DM offers greater operational flexibility with its HEP inverter. The engine can run at 1,047 rpm while delivering both traction power and HEP. Additionally, it can idle at 620 rpm (notch three) while still providing HEP for lighting and air conditioning when not in use for traction.[citation needed]
The Genesis uses trucks manufactured by Krupp Verkehrstechnik [de], which has since been acquired by Siemens Mobility. Newer Genesis locomotives reflect this change and carry the Siemens name.[citation needed]
Three models of Genesis were built by General Electric, the P40DC, P42DC, and P32AC-DM.
