The thing is the newer high horse power units are much more reliable than before. I have heard though that the SD90 's have had a number of problems. This mutes my point so I am going to shut up. <br />[/quote] <br /> <br /> <br />One reason, and there might be others, is the fact that two engines will burn less fuel than four engines. This of course saves the railroads money. Funny thing, railroads like saving money. They can get carried away saving money as is the case in the remote control engines.
