We'll carefully pry it open with a knife. The back plate is held into place by 14 pins. So, how does it work then? Well, let's open it up!.Warning: LEGO pieces were harmed for this answer How the switch works The correct 'go straight' switch position is: On first sight it looks like there is a spring in the switch which got stuck/compressed/., but I have no idea how to open this without breaking the track. I've also tried reversing the locomotive to check it isn't because the wheels are misaligned, but both the powered and non-powered wheels give the same result. The train either just goes straight (best case) or de-rails (worst-case).Īny idea what the cause is, and is there anything I can do to fix this? This happened with two different sets, bought about 5 months apart (but put in use at same time) with two different vendors across Europe, so I'd be surprised this to be a 'bad batch'.

As you can see the movable rail part doesn't completely close against the fixed rail track, causing the wheels to miss the turn. With two (out of three) switches we have the problem that the switch doesn't close properly anymore to perform the lane change (the position to go straight is fine). Just two weeks ago, my kid got a 60198 cargo train and we added a set of 60238 switching tracks.
