I don't know whether that's the case when it comes to the FX Line or not, but I personally find riding around on that thing to be a miserable experience. The buses are slightly too cold in the winter, and waaaay too hot in the summer. Plus, an articulated bus flying down a cruddy, poorly maintained residential street, filled with pot holes, makes for one incredibly turbulent ride. Not to mention that it crosses the tracks of a freight train, which it frequently has to be diverted around, causing trips to take longer than they did before the route was modified from the original Line 2 (previously Line 4) routing. I guess it works for some people, but I feel so stressed and agitated after even just a short trip; I would have been happier if they just added more busses/trips and removed a few stops to speed up the trip. But that's just me. End rant.
