What engine is in a GO train?

The Iron Heart of the GO Train: Understanding its Powerful Engine

GO Transit, the lifeline connecting the sprawling communities of the Greater Toronto and Hamilton Area, moves an impressive number of people every single day. In 2024, that number exceeded a staggering 53 million riders! While the iconic Bombardier BiLevel cars offer comfort and efficiency to passengers, the real muscle behind this operation lies in the locomotives that pull them – specifically, the MPI MP40. But what exactly is powering these iron horses of the rails?

The workhorse engine found within the MPI MP40 locomotive is a powerful piece of engineering designed for both reliability and performance. It’s essentially a highly robust and efficient diesel engine built to meet the demanding needs of commuter rail service.

Specifically, the MPI MP40PH-3C (the most common variant in the GO Transit fleet) houses a 16-cylinder EMD 710G3C-U2 diesel engine.

Let’s break that down:

• EMD (Electro-Motive Division): This indicates that the engine was designed and manufactured by Electro-Motive Division, a division of Progress Rail, which in turn is a Caterpillar company. EMD has a long and reputable history in producing railway locomotives and their components.

• 710: This refers to the engine’s bore diameter, indicating the size of the cylinders. The 710 series engines are known for their longevity and fuel efficiency.

• G3C: This designation specifies a particular generation and version of the 710 engine. It indicates the engine block design and various performance enhancements.

• U2: This denotes further upgrades and modifications within the G3C series, typically relating to emissions controls and overall system performance.

This engine generates a substantial 4,000 horsepower. This allows the MP40 locomotive to efficiently haul multiple BiLevel cars, even up moderate inclines, maintaining consistent speeds crucial for adhering to strict commuter schedules.

The choice of a diesel engine is strategic. Diesel engines offer a good balance between power, fuel efficiency, and operational practicality for a commuter rail system. They provide the necessary torque to accelerate and maintain speed, and they are readily refueled and maintained within existing infrastructure.

Beyond the raw power output, the EMD 710G3C-U2 is also designed for durability. It’s a robust engine built to withstand the rigors of daily operation, contributing to the overall reliability of the GO Transit system. Regular maintenance and preventative checks are, of course, vital to ensuring the engine continues to perform optimally over its lifespan.

So, the next time you’re riding the GO Train, take a moment to appreciate the complex and powerful engine working tirelessly at the front of the train. The EMD 710G3C-U2 is more than just a machine; it’s the heart of a vital transportation network connecting the GTA and Hamilton. It’s a testament to engineering ingenuity, delivering the power and reliability necessary to keep millions of people moving.
