6,000 Horsepower (or for you metric folks 4,476 Kw) will return.

The time will come again for the 6,000 horsepower locomotive how about SD90ACe, ES60AC ????

OK, I'll be very patient, since it won't happen for a while. The 6000 HP net engines currently running in GE AC6000s do not meet tier III emmissions standards. So, the builders need to develop a new power plant that can put out that level of power. IF they can find buyers for them, first.

Adhesion also seems to be a problem at this level, so 6000 HP may just be too big.

         The 1000HP/axle issue has been around before, when GE introduced the Dash 8 40B which had a reputation for being slippery. That problem has been solved with the performance of the P42s proving it. The real problems were in the power plants, which as I have noted before are going to be solved when some one finds the$ and the customer intrest to get the project off ground zero.

upand csx are running the 6000 hp ge engines still.

I've also heard that the railroads prefer to have lower-horsepower locos in a consist because if one craps out, the train can still move.

 i.e. If a train with two 6000hp locos suffers a failure with one of the engines, the train will most likely be stalled (50% of the pulling power gone).  But if it has three 4400hp locos and one conks out, it can at least keep moving, albeit a lot slower (lost 33% of the pulling power).
