Hi David
I personally do not feel the need to compensate rolling stock at all in 014. The flanges are the same as 00 finescale and unless the track is awful (either in error or by design) then it should stay on the track. ?This is not the same in P4 where the flanges are so fine that compensation is much more necessary. Locomotives of course are a different matter where compensation or springing help keep all the wheels stay in contact with the rails to increase the chance of collecting power and help traction. Some though would eschew compensation, keep the chassis simpler and go for a stay alive capacitor and clever DCC decoder. The latest Zimo decoders have a detection device so that if the loco is stopped on a dead piece of track, the decoder detects this then ?moves the loco forwards a few millimetres until it reaches power before stopping. Not sure about S7 wagons - better ask John about that one.?
