Here's your sign.... anytime you want to see work get done, with heavy loads... ships, freighliners, trains, whatever, where there is heavy weight involved, invariably, the drive plant chosen is a turbo diesel. End of subject matter. It's never a race, when work needs to be done, it's what kind of power your motor makes under the peak curve that matters, and how far away you can stay from being at the peak curve while doing the required work, leaving a margin of safety for the longevity of the motor.

Actually, in many of your examples, the drive plant chosen is actually electric. Trains for example, electric motors, that might be powered by diesel gen sets. Cruise ships are powered in the same manor.

It's also worth mentioning that nearly everywhere, engines are rated by hp. Certainly in the oil field engine skids are never measured by the torque output, always hp. Same goes for those motors on the cruise ships.

Too funny... I've read sooo many responses with errors from Niner

Actually, he makes a good point. You don't want to be operating at peak power all the time. How often do we call for rated power from our engines? Low and mid range power is very important in normal operation. I would rather have 20 more hp at 2000 RPM than 30 more at 5000. That is a diesel's forte. Turbo gassers do pretty well in that respect as well but not as efficiently.
