CtDOT's shared fleet with MNRR needs are a bit more complicated. For one thing at this time they require two types of traction power, whether going to either GCT or in the near future NYP. So D/M Chargers would only add to the complexity - you'd have AC/DC/Diesel. Ultimately, they may only use diesel until they reach territory which forbids it. So, west of Harold, and south of 125th for unelectrified branches, will be the only electric stretches. There are also speed restrictions when using DC.
You could conceivably use D/M's like the ALP-45DP for MNRR/CtDOT branches, but electrification of Danbury and Waterbury would be cost-prohibitive. Someone upthread mentioned DMU's; I agree. You'd need FRA compliant, with transfers at either Devon, Bridgeport, SoNo, or Stamford. Guillietti is not interested.
North of New Haven, I do think electrification does have some utility, but of course, has extremely high costs in both installation and fleet. A Charger variant with Diesel and AD could work.
East of New Haven, you're fine, of course.
Next stop, Willoughby
