Can someone please explain the need for third rail or wire from Penn to DV. I must have missed something along the way, just a simple railroader who makes big sh!t stop and go.
As for MNRR into Penn via DV if it ever happens, dedicated dual mode locos with retractable 3rd rail shoes.
125mph locomotives maybe before I retire, to get those speeds going to require some $$$ for infrastructure improvements. MNRR isnt going to care if it hits 125mph. Through the years the speeds on the upper Hudson between POU and CRT have gone down.

3rd rail on west side line? Too many trespassers that could get fried. 12.5 Kv 60 Hz NYP to DV would be best. Sunnyside converter substation cannot provide more 25 Hz power. One reason Hell Gate line converted to 60 Hz..
I’m just a simple railfan and the only reason I can imagine is because New York City would want to eliminate all diesel trains from Manhattan. Amtrak wouldn’t care to undertake electrification on its own, and MNRR wouldn’t bother, as long as both own dual-mode (diesel/third-rail) locomotives.
And in the event of New York successfully kicking the locomotive change point out to Poighkeepsie, why do we need wire when third-rail substations don’t need to be that
big or that
close to the rail? Four substations built a block away from the ROW in the garage of a commercial building is an option. You’ll never exceed 80 mph from NYP to DV anyway, nor will you easily convince the residents of Westchester and Putnam that overhead is necessary (and somewhat unlike the old New York Central, the locals own a good share of MNRR.)
