Supreme Power (Qiji 42101)

About this set

The KEEPPLEY 42101 Power Supreme is a 305-piece steam locomotive build from the Super Transformation series, rated 6+ with a 2/5 difficulty. The red frames, black boiler and yellow accents are all on the box, along with a chimney, cab, tender and multiple wheel sets. Sort the three colors first and install the gear linkage before closing up the shell, since the wheel and gear assembly is much harder to fix once the body is together. Its selling points are the 3-in-1 creative builds and the linked drivetrain with free switching between transport modes, so pushing the finished loco shows the gears meshing. A good first mechanical build for kids 6+, and a useful starting point for train-chassis MOCs.
