Given how the state has been fairly incompetent at funding transit (in general), I wouldn't hold my breath for any changes, especially the ones from the CMAP report, until it actually (if ever) happens. Also freight railroads. Some play nicely (BNSF), others not so much (CPKC).
A range-extending battery for service to Joliet would be understandable, but fully battery trainsets on publicly owned tracks is damning.

It may be their experience with the many substations, heavy conductors, and DC traction motors has soured it on any expansion to other routes.NICTD South Shore has converted to AC traction motors. It doesn't take rewiring the entire physical plant to use AC motors.

They've seen a maintenance benefit as well—one of the benefits of the SD70 purchase they highlighted was the increased reliability on their modern Highliner equipment vs the DC drives on their existing locomotive fleet.
