The EMD four cycle engines have had some issues with reliability but are used in new US locomotives. The 2 stroke engines do not meet the Tier 4 standards for diesel emissions.

Norfolk Southern is rebuilding DC locomotives as AC locomotives and reusing the original two stroke engines as a work-around.

I can remember the good old days when the Nickle Plate ran Berkshires down the tracks at 80 MPH. That would get a young person's attention. Steam locomotive drivers (the big wheels driven by the cylinder) were not balanced due to the connecting rods. They pounded the ground for a distance around the passing locomotive.
