Why Melbourne’s $34B Mega-Project is Using Tiny Trains

Melbourne's Suburban Rail Loop (SRL) is a $34 billion mega-project, but why are the new Alstom Metropolis trains so small compared to standard Melbourne Metro trains? In this video, we dive into the brutal civil engineering logic behind the SRL's 4-car short trains. By shrinking the trains to 93 meters, engineers can drastically reduce the size of the underground station boxes being excavated right now for SRL East. Shorter stations mean less excavation, less concrete, and billions of dollars saved on underground construction.
