I wonder if the LIRR recovers the train braking energy for reuse in some way. I wonder how much energy it could save and how that compares to overall train energy usage.

I call BS on: "Just now battery costs are impacted by EPA restrictions." If the cost of restrictions are way down on the cost drivers then this morphs into political axe grinding.

Granted that the regulation costs on a typical lead acid battery are estimated to be a few dollars. The problem here is that the packs in pure and hybrid EVs are NiMhd or Li-ion. Not lead-acid! For EVs lead acid packs are very poor performing batteries.

Please look at this report to get an idea of what the costs are:

The costs on the Tesla motor packs are not due to regulation - it's simply that they use a lot of very expensive batteries. The expensive part is not due to "regulations."
