If express service was never eliminated in the Bronx.....

Okay, as a Yonkers commuter, I always take the Bee-Line bus to Woodlawn and 242 Street. The thing is, there is NO express service. The always runs local, why was there never a express service for the ? Bronx residents would love to catch a express train to Manhattan.

And the ? Why is there no (8) express train for it? The middle track isnt being used for anything unless theres a G.O.
