Hybrids not just for cars anymore

GE is getting set to release a new diesel-hybrid train locomotive, first one to be on tracks in 2010. I suspect that adoption is going to be based more on retirement of existing locomotives, and will take many years to make a significant impact on fuel consumption by trains. It would be awesome if this were to be used for commuter rail lines in addition to freight. Additional summary at Inhabitat.

Seems like an incremental step in efficiency improvement, and the marketing tags are impressive. Comparing NOx emissions to engines of 20 years ago, and lifetime carbon emissions from the engine to the annual emissions of automobiles doesn't seem all that impressive.

Lets hope this unit sees high adoption rates until something better comes along, every improvement helps.
