Where does the DC power come from to run all the trains on the third rail portions of the system? I know there's a basement full of power conversion gear under GCT. But, does that power the whole system, or just up to some point and then there's feeds (and AC/DC conversion) from the local electric utilities?

Same question about the AC for the overheads.

if you look along right of way you see a substation roughly every two miles, it has transformers, rectifiers and section circuit breakers.

All the power used in NY City and lower Westchester County is feed off the Con Ed power grid,part of the Harlem line(Katonah to Southeast )is
off the NYSE&G power grid.
For the New Haven Line,Con Ed feeds,Conn/NY State line to Woodlawn,and Shell to near CP Gate on the Hellgate route,
CL&P and UI Feeds State line to the Fair st phase break in New Haven.
Back in the 25hz era the power plant at Cos Cob and a few Rotary converters were used,1 was at West Farms(Con Ed),
1 was Cos Cob (CL&P),not sure if the 3rd one was off the UI grid near New Haven

Way back in NYCRR days, the railroad powerhouses were at Yonkers and Pt. Morris.

There is a shared sub station now right at the new haven yard across from the new haven PD
