The accuracy of this post is on point..
However, the only differences is that in Brooklyn. The B46 LTD went local after Avenue H to KP, B44 Limited went local after Avenue U to Emmons Avenue. Yes, limited service concept but with less stops with SBS. However, SBS hasn't done anything good in my opinion in Brooklyn.
Bad enough TA orders new buses for Manhattan and Bronx since they are way more priority than Brooklyn.
If you want premium service than premium buses need to be here and now, the folks of Sheepshead bay and points south Brooklyn are screaming at the heads of the MTA to possibly scrap the B82 SBS. Although some of the machines are being installed already there's plenty of opposition on this. Let's see where this goes?
