================= 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...

Confused !!!
2 stroke high capacity engine generating less power...
Why can't a 4 stroke engine be used generating comparatively high horse power...... will also be less than its max power.
Thats how airlines do!!!!

4 stroke engine has one power stroke in 4. 2 stroke has one in two.
Hence you have power availiable at output twice as many times in 2 stroke as in 4 stroke.
Where power considerations are significant 2 stroke is used.

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.
