||Pimlico - Train On Rail System, Pimlico - Height Adjustable Platform, Pimlico - Boat On River. The underground tube is on a rail system, which allows it to move in a linear direction. The tube is reversible, so it can go in both directions. The rail system is modular so it can be expanded when needed. On the river was a platform that had hydraulic legs that could adjust the height of the platform, this can be useful as the water level rises and sinks, so the platform can adjust accordingly. The platform was strong enough to hold heavy machinery. The boat on the water uses a motor driven rotating wheel with flat panels that push the water behind it and propel it forward, this allows it to glide across the water at a high speed.
