>>9870410>>9870474The new wheels roll far worse than the old ones with the metal rod since the newer ones have the wheels separate. The whole point of the axle on train wheels is so that the wheels spin at the same speed, they're not like car wheels where they spin at different speeds. They could've gone with technic axles or even make a new 5-long bar for that but the system they use right now actually makes the trains worse.
