Greetings all!
I see my NYTIP series has gained some traction here, so allow me to clarify some things.
For the CPW de-interlining, I envision all routes using full-length trains. I have since revised that proposal to have A/B on Inwood and C/D on Concourse to avoid "rocking the boat" too much with regard to yard access.
Having two full-time services on Concourse is intentional and designed to encourage ridership. Before the Rona, I used to joke that the most frequent service on Concourse was the taxi because taxis came more often than buses or trains!
Also, bear in mind NYTIP is a long-term improvement strategy. De-interlining certain corridors is just Step 1 of that strategy. I know some say we shouldn't think of such plans in light of the Rona knocking out transit ridership and potential doomsday cuts that make 2010 seem like a dream in comparison; however, I disagree. I think this is the best time, because we effectively have a blank slate in some ways. There will likely be a permanent shift in travel patterns owing to telework, for one, and how MTA recovers will depend on their ability to adapt, IMO.
Criticisms of cost are definitely fair, but also remember that the supposedly broke state somehow has money to widen highways, and the supposedly broke city keeps subsidizing empty boats - both to the tune of hundreds of millions of dollars. My plans may not be perfect, but I think we can all agree on the need to Save Transit and convince city and state leaders to get their priorities in order. Thanks for reading and commenting!
