Marine Diesel Engines

Making waves

We've been designing and building low emission, high-performance diesel engines used in locomotive, marine and stationary power generation market applications for more than 50 years.

Our world class engine manufacturing facilities in Pennsylvania are among the largest & most modern in the world for medium-speed engines. With more than 22,000 engines in service worldwide in some of the most challenging industrial environments, Wabtec medium-speed engines are proven to be among the most dependable, durable and fuel-efficient engines available in the market, with better uptime and lower life cycle cost for operators. Our engines are supported by an extensive global parts distribution and service network.

Product showcase

Meet the cleanest Wabtec medium-speed engine

Our MDC engines are the most technologically advanced and fuel-efficient medium-speed diesel engines ever built by Wabtec. These engines meet EPA Tier 4 & IMO III emissions standards through exhaust gas recirculation that does not require urea based after treatment.

No urea! No kidding!

As a global leader in emissions reduction solutions, Wabtec was the first to launch medium-speed diesel engines certified to meet the most stringent T4 emissions requirements, through advanced EGR technology without urea after treatment.

Phoenix Reisen's Amadea to undergo engine retrofit for greener ops

Phoenix Reisen's Amadea to undergo engine retrofit for greener ops

Wabtec Corporation auxiliary diesel gensets, designed to reduce emissions, are to be fitted to Phoenix Reisen's Amadea by September. The Amadea will receive two medium-speed marine diesel engines, L250 and V250, which use advanced EGR technology to minimise formation of NOx during combustion, thus meeting IMO III and EPA Tier 4 emissions requirements.
