The ACE trucks were the only ones to pick that one frog of the diamond. And the track is curved as it goes through the frogs in both directions compounding the complexity. Pointed axle trucks don't have any side-to-side movement of the axle in the side frames. And once the side-play was greatly reduced the picking problem disappeared. Ben Trousdale
