The #904 is indeed a nice engine to switch with. That 567 sound reminds me of my freight days. Besides, I want to see how the 3248 holds up after 50 years of service.

I never realized the complete polution reduction of these engines. That report really is amazing as to the emission reductions. But obviously they don't mention 3249's problems.

3249 has been having bad loading problems and it needs new circuit boards, last I heard.

I saw 3248 passing through Back Bay yesterday with a transfer from BET.

Does 3249 become eligible for a full refund under the Massachusetts Lemon Law if its electrical problems are not resolved? :wink:

If they were a little older they would qualify for clunkers ;)

The NRE press release linked several messages back was very interesting, it is curious that they chose not to identify what specific locomotive they are comparing these units with. Looks from the numbers like it might be a comparison with a sixty year old GP7 with a BSFC up around .408 lbs. per BHP-HR and 18% adhesion, and most modern diesels will make the GP7 look similarly uncompetitive. They fail to mention that you have three diesel engines and generators in the Genset unit requiring shop time for scheduled maintenance rather than one. I wonder if recently built locomotives are going to prove durable enough to still be around in sixty years so people can make comparisons with their performance.

The engine-generator sets in a genset unit are all mounted on sleds that can be swapped out with little trouble, so the locomotive can be back in service in just a few hours while workers look at whichever engine set is broken or due for inspection.

That design sounds great if you have a fleet of them. But if you own two of them, I don't see buying extra engines to service while the units are in use is very economical.
