The quickest way to get going on a Rock electrification would be to order 20-ish straight electric locomotives for 1500vDC, electrify both the main and branch of RI, and then instead of buying EMU, pull the longer/express trains on both MED and RI with the former RI trailers, and run the locals/shorties with the former MED bilevels. That said, MED needs bilevels anyway, so maybe it makes sense just buying all EMUs.
