Siemens (and Bombardier) have indicated that they can sort of polish their Charger and ALP-45 DP locomotives, respectively, to meet third rail requirements into Manhattan.Is there a dual mode version that is being developed?
And last time I checked, the LIRR is planning on retiring their locomotives in 2024, and Metro North in 2025, so a large contract could get signed in 2020...However there is nothing under real development. Those are all based on paper study analysis. There is quite a ways to go from there to an actual realization.
I am sure given enough money almost anything can be done.
