A lot of these ideas come from Newark City Hall / RPA which factors in the Future growth in Newark and surrounding communities
City Hall doesn't have the money. NJT is a statewide agency, part of a broke state from whom they'll be begging the cash; and NJ will be begging for cash in turn from an even worse-off federal government.
Some Bus lines like the one which runs through Harrison will have trouble keeping up with population demand from the New Mega Development
What "new mega development" would that be? And what light rail can ever handle significantly more passengers than bus service anyway, at a significantly-higher average speed, while running on the street? NJT already operates articulated buses whose capacity is competitive with LRVs.
It's looking like Broad Street will see something similar happen, and south Newark which would demand a streetcar or subway under broad street which has the support from City Hall. It was in the NJT 2020 proposals, but they axed it when they killed the Midtown link
I recall absolutely no rail tunnel under Broad Street in any NJT 2020 proposal. Nor is anything happening in South Newark.
Which is why the RPA and some transit groups call for the PATH to be expanded; there is massive redevelopment planned for around the Port/Jersey Gardens but no transit, same with Midtown Elizzy(?) so the need is there or will be there soon
Need for what? I already said that PATH is not going any further south than what they have already planned. There are no plans to go anywhere else; and even to the EWR monorail station at Waverly is extremely iffy at present. Saying that development is "planned" means nothing; there was the Allied Junction complex once "planned" for the Frank Lautenberg Station at Secaucus Junction, for example.
A bus company is not going to have much leverage in Urban Jersey, Coach USA does interstate bus traveler not Urban
Coach USA directly operates routes 24, 31, 44 and 77 in Essex County. They own the former Suburban Transit routes in Middlesex and Mercer Counties, as well as Short Line that serves the Route 17 corridor. They also run just about all of the non-NJT bus routes in Hudson County, and run local buses under contract to NJT in Passaic and Bergen Counties. They are no small player in terms of urban bus service, nor even small within New Jersey as a business, having their Northeast Division headquarters in Paramus.
Red and Tan shot themselves in the foot after scaling back service to the area
If NJT ran those routes, the cuts would be more draconian. R&T's coverage is still substantial.
Bus Rapid Transit is planned for Springfield, Mt Prospect, and Bloomfield Ave(nues?); they could be converted to streetcars if needed
NJT has zero plans for "streetcars". And the "need" for a streetcar versus a bus cannot be demonstrated.
