Big Old HOLT Engines COLD STARTING UP AND COOL SOUND 2 

Very much

Oh yes

Yes very interesting early diesel track machines

Son parte de mi vida 🎉

@@Oscar-fq1rbthese are gas engines buddy

A steam traction engine is always going to beat a diesel tractor for torque, especially starting from a stationary position. The reason is fairly simple: Even though those Case traction engines usually had just the one piston doing all the work, the force on the piston (and therefore the torque it could make) was only limited by the maximum boiler pressure. Plus the force could be consistent - as long as the steam valve is open, you have maximum pressure applied to the piston, even if it's not moving or is moving very slowly. So the torque is not only high, but is also just as consistent. Diesels can produce equivalent torque, but not as consistent and they can't do so from rest - you need some form of clutch to transmit the power, and that's going to limit the maximum torque at the wheels. The only way a diesel can produce high and consistent torque from rest is indirectly: For example if the diesel engine is driving a generator and this is delivering power to an electric motor - because those can make torque while stationary. Not forever though - if you jam up an electric drive, you risk overheating and burning out the coils in the motor, or overloading the circuits providing power to it.
