= Vactrain
{wiki=Vactrain}
A "vactrain," short for vacuum train, is a proposed mode of transportation that involves a train traveling in a low-pressure or vacuum tube. The concept is designed to reduce air resistance and friction, allowing the train to reach high speeds with greater energy efficiency compared to conventional trains. Key features of vactrain technology include: 1. **Vacuum Environment**: The train operates within a sealed tube that maintains a low-pressure environment, significantly reducing aerodynamic drag.
