Unlock Fast Travel in The Cauldron South of LEGO Batman

Published on May 20, 2026 | Translated from Spanish

In LEGO Batman: Legacy of the Dark Knight, unlocking Gotham's fast travel points requires solving puzzles at the SubWayne stations. The Cauldron South puzzle is one of the most complex: a powerless crane and a blue container block the entrance. The solution isn't where it seems. You must ignore that obstacle and search the right corner of the tunnel.

Gotham City subway tunnel interior, LEGO brick-built station The Cauldron South, broken crane mechanism hanging idle above a blue shipping container blocking the entrance, player character Batman standing at the right corner of the tunnel, pressing a hidden activation switch on the wall, yellow sparks emitting from the switch, glowing arrows showing the correct path, cinematic technical illustration, dark blue and grey industrial tones, dramatic underground lighting, dusty air particles, photorealistic engineering visualization, action demonstrating the puzzle-solving process

The hidden mechanics behind the crane and the container 🎮

The technical trick lies in the game prioritizing interaction with the secondary environment. By driving a vehicle toward the right corner, you discover another container that can be flipped over. Behind it appears a shed with a lever. Activating it restores power to the crane, which then moves the initial blue container. The design forces the player to explore outside the obvious path, using object physics to progress.

Because yes, the crane was working, it was just on strike 😂

In other words, the crane had power but didn't use it until you activate a hidden lever in a shed that appears after flipping another container. It's like if your microwave at home didn't work until you found a switch behind the sofa. Good thing LEGO puzzles don't apply to real life, or you'd never leave the house.
