3D Model of a Subway Train for 3D rendering/CFD analysis. Subway trains are a crucial component of urban transportation systems, designed to efficiently move large numbers of passengers within cities and their suburbs. These electric trains typically operate underground, although they may also run above ground in certain areas. The first subway system, the Metropolitan Railway, was constructed in London in 1863, marking the beginning of rapid transit as we know it today.
