Oh, gee...Here we go again...Do you actually think that people at stations are going to get on an train that randomly shows up? They're going to try to wait for the , (which brilliantly runs via the line), and they'll never get to Manhattan.
What makes you think that Jamaica Center riders want to take the , which doesn't go where they're going?
Listen, Wallyhorse. Once again, it isn't just about sending trains to every station. It's about sending trains that riders RECOGNIZE. Can you expect a Culver line rider to understand where a re-routed train goes? I really don't think so. You can send the to Far Rockaway for example and say, "Oh, this is great! Far Rockaway riders now have service!" But they won't have any idea what a train is doing at Far Rockaway, and won't get on it.
