The Knoxville SE10B and SE15B models have 1,050 and 1,560 hp-equivalent power output, respectively. Using four-axle EMD units, both models weigh up to 276,000-lbs. and are fitted with a Series 2000 MTU engine, ZF gearbox, TMV Control System wheel-slip prevention system, and other modern technology. The patented switch locomotives use a high-speed diesel engine with a low-speed alternator.
The order was partially funded with $10 million from the Texas Emissions Reduction Plan, administered by the Texas Commission on Environmental Quality. The locomotives are estimated to pollute up to 90-percent less than the units they are replacing while saving up to 50-percent on fuel consumption under equivalent load capacities. The locomotives have a starting tractive effort of about 80,000 pounds.
The locomotives have been out shopped in a bright green paint scheme. The locomotives carry the logo of The Woodlands, Texas,-based Chevron Phillips Chemical.
Knoxville has manufactured and re-purposed more than 500 new and used locomotives since its founding nearly 20 years ago.
I did not know that anyone wanted to use 4 axle trucks, and that any were available!
Unless the statement was “Using four-axle EMD trucks, both models weigh up to 276,000-lbs ” was in error and the trucks used were the 2 axle Blomberg’s shown in the photo.
Locomotives do not have a druveshaft. They have a connecting shaft between the prime mover and the alternator/generator that provides the power for the thing to move.
