Space Rail Level 6

The SpaceRail Level 6 (Model 231-6) is an advanced-level, do-it-yourself marble roller coaster kit designed for users aged 15 and older. It features a massive 60 000 mm (60 metres) of track rail and a motorised elevator to create a continuous, looping marble run. Because of its complexity, it is highly regarded as a STEM learning tool that challenges engineering skills, patience, and spatial thinking. 

Key Specifications

• Track Length: 60 000 mm (60 m)
• Total Pieces: 1 155 pieces
• Steel Balls: 8 marbles included
• Assembled Size: Approx. 138 cm x 37 cm x 44 cm
• Power Source: Requires "C" or "AA" batteries (depending on the exact manufacturing batch) for the motorised lift
• Assembly Time: 1 to 2 days of continuous building 

• Motorised Elevator: Automatically moves the steel balls from the bottom back to the top.
• Complex Multi-Level Track: Includes a series of loops, sharp curves, steep drops, and spirals.
• Seesaw Splits & Forks: Features 7 seesaw parts and 3 fork parts to split the path, sending different marbles down separate tracks simultaneously.
• Glow-in-the-Dark: Many versions include a luminescent track that glows when the room lights are off. 

1. Precision Cutting: You must cut the plastic tubing to exact specifications from a single long roll. Measure twice before cutting. 
2. Smooth Rails: Ensure the two parallel rails remain perfectly spaced. If they spread too far or pinch together, the steel marbles will stall or fall off. 
3. Fine-Tuning Loops: The engineering fun comes from adjusting the track holders and metal rods to find the perfect angle so momentum carries the ball all the way through the loops.
