Sending the (J), or the future (T) across the Brooklyn Bridge

Is something about the word "No" not sinking in?

 

the last trolley crossed the bridge in 1950. At lot fewer people owned cars in New York in the 50s. Now days, it makes no sense to turn over vital road space on a river crossing in a city that's mostly on islands...

I've operated one of those trolleys that ran in service over the bridge (if I recall correctly, 4573 did operate on the Brooklyn Bridge at one point.)

Even if the (MTA), city, and state had the funds for such a project where is the justification for it? There are already sections of Brooklyn, Queens, Richmond, and the Bronx, with more pressing needs for transportation IMO.

 

Its like the idea popped in his head because the nearby bridges have trains on them, why not this one? And where to put the portal at that, the feeder roads for the Brooklyn lie right underneath, while the other two are more linear in approach. He'd have a better fantasy argument converting the outer roadways of the Queensboro (too bad you'd end up with the same problem the Manhattan Bridge had with uneven load distribution) and merging with the LIRR in Sunnyside yard to form a Super Express lol.

 

Oh, and what would run into lower Manhattan being that the (Mx) is already gone...

I don't see why you'd want the SAS to split into no less than four different branches, like in your first proposal. Not only does the two-track trunk line lack the capacity to support that many branches, you'd also introduce more clutter into the current service pattern which is cluttered enough as it is already.

An "Atlantic Avenue Super Express" - if that's what you really want - could also be realised by extending the SAS from it's projected terminal station at Hanover Square into Brooklyn.

Like others have already said, there is plenty of room in the Montague Tunnel to run a new service there now that the (Mx) is gone. It would make so much more sense to do that instead of blowing billions of dollars on putting train train tracks on the Brooklyn Bridge and building portals and disrupting subway service on both sides of the bridge.

For example, let's take that proposed Atlantic Avenue Super Express shown in the map in your original post. It would make far more sense to run that line via the Montague Tunnel, rather than spending a lot more money to run it over the Brooklyn Bridge just so there can be a train line over the bridge.

I found out that a typical light rail car weights 98,000 pounds. That's less then the 140,000 pound Q type car. So light rail might be a good option for the Brooklyn Bridge in the future. Also a typical light rail car should carry about 240 passengers. A full Q type train could carry about 300 passengers. They could hit speeds of 72 mph faster then the Q type car speed of 55 mph.

Light rail is not necessary on the Brooklyn Bridge, and neither is any other type of transportation. This area in particular is a very transportation-rich area of the city, with the (slight) exceptions of Brooklyn Heights and the Lower East Side. The Brooklyn Bridge alignment is not necessary at all for any of the other service proposals you described (an Atlantic Ave. corridor, even if there were demand for it, could be done through a line branching off the Montague St. tunnel).

It could be a Red Hook/DUMBO/Downtown Brooklyn light rail extension. In this map I created the grey line runs across the Brooklyn Bridge from Chambers Street to Smith and 9th Street.

Why are there light rail lines every two blocks? The MOST light rail lines that area would need is 2-3.
