Wow, interesting. I wonder how quiet those engines will run. The effect on air quality should also be noticeable. The cost savings on fuel alone makes this a worthy investment. Hopefully they can electrify the entire fleet quickly.

From what I recall (and please correct me if I'm wrong), when Metra took over the old interurban lines, many of those lines were originally electrified (overheard catenary wire) and then years later were converted to diesel. It seems like we are doing a 180 by going back to electric power.
