I always wondered why there wasn't a "local Bronx portion" between Fordham and Flushing. This route could be very useful and even a couple stops on the current Q44 could be served by the local instead.
Iirc pending finalization of construction, all trips on the Q44 are supposed to be sent to Jamaica depot to reduce unnecessary short turns and layovers for reliefs. Still doesn't excuse the extension to make trips longer.
The Q44 is one of the handful of routes in the city that became so successful it hurts itself in the long run. Imagine being the OP that had to drive on the Q44 pre-1999. Even the Q20A/B is only able to do so much. I remember reading the (original, and not pre redesign, the original original) Bx36 was also replaced slowly by the Q44, giving it more weight to carry. If they needed a Bronx-Queens connector, could have found a way to make an "express route" between West Farms and Flushing. All this short turning still gonna upset passengers.
The main problem is layovers. There is definitely not enough space for both the Bx9 and Q44 to be rerouted over there. At the very least, the Q44 is still gonna have to end at/still serve West Farms so the rerouted is basically moot. Besides, the current Q44 route between Parkchester and West Farms is already as straightforward as it can get. No need to add more unnecessary turns especially on narrow streets.
