================= How Diesel Locomotives Work ===================
The Engine and Generator
The main engine in this locomotive is a General Motors EMD 710 series engine. The "710" means that each cylinder in this turbocharged, two-stroke, diesel V-12 has a displacement of 710 cubic inches (11.6 L). That's more than double the size of most of the biggest gasoline V-8 car engines -- and...

It's because of the fuel used. 2 stroke engines can potentially generate twice the power of a 4 stroke engine, with a simpler, lighter and easier construction. But for engines that that run on petrol or gasoline, 2 stroke engines will result in considerable fuel wastage because the input to the engine is a mixture of fuel and air ( pre-mixed) that is ignited inside with a spark-plug. After the fuel-air mixture burns up, the valves to let out the burnt gases and the valves to let in the fuel-air mixture will be open at the same time, resulting in fuel escaping through the exhaust vents leading to fuel wastage.
