Berlin, Germany (September 19, 2006) - Cummins exhibits the Stage 3A/Tier 2 QSK60-L locomotive engine for the first time at the 2006 Innotrans show. Released especially for mainline freight and passenger locomotives, this engine provides unrivalled levels of durability and reliability.

The QSK60-L, with an output range from 1492 to 1940 kW (2000 to 2600 hp) combines the proven durability of the Cummins QSK Series making it the right choice for the most arduous rail applications. This new locomotive engine will be available in January 2007, and meets the Environmental Protection Agency's (EPA) Tier 2 emissions requirements. Using leading edge technology, the 60-litre engine is capable of meeting the latest Stage 3A locomotive emissions regulations that take effect on January 1st 2009.

Steve Dodman, Cummins Locomotive Engine Business Leader says, "Cummins has invested in the right technology, people and infrastructure to achieve an in-cylinder emissions solution that ensures minimal installation impact. This offers significant benefits for both rail operators and vehicle manufacturers providing long term equipment stability. The success of the 60-litre engine has already been demonstrated in mainline locomotive installations in Namibia coupled with the first two orders of Cummins QSK60-L powered locomotives in Angola for delivery on-site by end 2006".

Cummins, as a pioneer in emissions research and development, uses the latest in-cylinder advanced combustion technology achieving 30% reductions in emissions of Nitrogen Oxides (NOx) and over 65% reductions in Particulate Matter (PM) compared to Tier 1 levels. This advanced combustion solution provides a stable engine architecture that will carry customers through to Tier 4 in 2011 with the addition of aftertreatment.

The QSK60-L utilizes a Cummins modular common-rail fuel system specifically designed and tested for engines operating with high load factors in tough conditions. In fact, the modular common-rail fuel system maintains high injection pressures regardless of engine speed for increased power output and emissions compliance.

Furthermore, the 60-litre engine platform is a recognized mining industry standard with over 4,250 engines in-service which means increased confidence for locomotive manufacturers. Cummins advanced in cylinder combustion and power cylinder technology enables the QSK60-L to meet the latest emission regulations. Engine sociability is further enhanced as the QSK60-L virtually eliminates visible smoke at all loads.

The QSK60-L utilizes a proprietary power cylinder design. By using FCD (Ferrous Cast Ductile) single-piece cast iron piston, even expansion & contraction is achieved during thermal cycles, while piston cooling nozzles provide a high oil flow rate. This design virtually eliminates any risk of power cylinder failure before engine overhaul, together with the benefit of very low oil consumption. This translates into exceptional performance and durability even for intensively used locomotives operating a high number of hours.

Locomotive availability is enhanced for 24/7 operations by the factory fitted Eliminator™ oil filtration system and Centinel™ oil replacement system. Equipped with these options, QSK60-L oil service intervals can be dramatically extended while ensuring the best possible engine lubrication. They also offer a major reduction in used oil & filter disposal.

Cummins electronic architecture for Quantum engines features on the QSK60-L. The engine's electronic control module is fully isolated from any detrimental thermal or vibration loadings. A standard set of 37 sensors are located throughout the engine. The engine is also equipped with the Cense monitoring system which uses 16 exhaust gas temperature sensors to enable individual cylinder health monitoring. The operator can download and undertake trending analysis with datalogs of engine duty cycle, fuel consumption, load factors, fault snapshots and stop-starts. A progressive auto-derate feature is available as part of the engine protection system, triggered when pre-set threshold limits are exceeded.

"The QSK60-L is an ideal locomotive engine either for re-power or new-build projects. It provides significant operational cost benefits versus lower speed engines whilst maintaining high reliability and a long life to overhaul," adds Mr. Dodman.
