Has anyone heard of using battery powered electric engines as an alternative to diesel electric engines? An abstract of a scientific talk claims the following:
"In this seminar, we will discuss opportunities for battery electric trains. Nearly all trains in the US are diesel electric. Adding battery cars to current diesel electric trains can deliver zero emission rail and 200 GWh of mobile storage to enhance power system resilience. One battery car can power a 100-car train for 450 miles. At a power cost of ~ 5 cents/kWh and near-future battery costs ($100/kWh), this addition to eliminate diesel use is cost-effective."
I don't know the engineering or economics of this well enough to know if this is even plausible, That 200 GWh is not the size of one RR battery car. Some simple-minded calculations based on the Tesla megapack - each megapack is ~3 MWh and weighs ~ 50k pounds. A 50 foot RR boxcar carries ~200,000 pounds, or four megapacks = ~12 MWh. Wonder what a power/load curve looks like for a 450 mile trip starting from a dead stop with 100 car train?
Still, this is an interesting idea - if feasible. As soon as you get out of the NE corridor, there's not much overhead power around anymore, so short of having to install a lot of catenary (at some tremendous cost?) maybe having lots of charged up battery cars statloned along the length of the RR is a way to do it.
