Well then send it to some other South Brooklyn terminal. It's not like we don't have options... And in fact, if you sent it somewhere on the Sea Beach, you could replace the on evenings and weekends with the , simplifying things. Finally, fourth ave has been begging for service ever since the brown went away -- here's an opportunity to give it to them.
Astoria riders may be pissed they don't get express service, but that makes a what, four stop difference over current? It also gives them more service to lower manhattan/downtown brooklyn, two growing jobs centers. The fact is that broadway is currently limited by a stone age service pattern that has trains switching from local to express mid-corridor. In an age where everyone is gasping for more subway capacity, letting this opportunity to optimize pass us by seems irresponsible. Right now the corridor runs about 30 trains per hour, and really can't add many more. With these service changes, we will get closer to forty five.
