I've always hated the idea that SEPTA did away with the "flip-over" (reversible) seats that the Silverliner II's/III's originally had, making half the people on the train ride backwards. With the Silverliner IV's and Arrow II's/III's being nearly identical and built around the same time, I could never understand why the Arrows had the reversible seats, while the Silverliner IV's had the "fixed" seats installed, instead of both (Arrows/Silverliners) having identical interior setups. There are many people (including myself) who HATE having to be forced to ride backwards. I always prefer facing my direction of travel.
