I have a feeling you mean the engines, not the boilers... but I'll keep that in mind. Those are in the stern section though and it's probably going to be a while yet before I get that far. Another extended break will probably be coming once I'm done with the middle section.One thing I remember hearing from a speedbuild video on this kit was that you need to be careful to align the drivetrain before linking the section with it and the section with the boilers. Otherwise, it will give you nothing but grief when you try to link them.
If you look at the first picture you can see hinge pieces and axles sticking out of the middle section. These mate to axle holes and the opposite hinge piece on the bow section. The second and third pictures show a big pin being put into place that locks them together.Do the two sections just slide together or do they latch somehow?
