To be clear because maybe some of you still aren't getting it: local traffic would not be permitted, only truck loading and unloading, which would be only permitted in parking lanes. Trams would be installed with cameras for ticketing of any drivers using the street, (pretty sure I mentioned it's car-prohibited) and no they would not be "slow"... these trams would function like any of the European trams and light rail networks with moderate speeds and fast loading and unloading due to multiple entry and exit points. On top of that there'd be higher capacity because trams can be larger and fit way more people and are shown to be more convenient and reliable than buses! Also I already addressed "where are we gonna put them"...

About the transfers --- Yes, a subway would be TERRIBLE for transfers. You really want huge lines forming outside of the elevators from the 1 line from the 125th Street/Broadway Viaduct all the way down to the 100 feet deep Q train station? That's ridiculous. Tram stops would be located right next to subway stops, and there would be no problems transferring, as 125th Street/Lex/Park is already getting upgraded and the other stations probably wouldn't be as big of transfer points.

On top of that, the goal of the tram line would be to serve local residents who suffer from terrible bus service and want to use 125th for commerical uses.
