147 rail lines with roughly 1,900 trains moving on them at any weekday moment, drawn in WebGPU with no rendering library underneath. The clock runs at sixty times speed by default — a minute per second — so the whole network pulses, and five station complexes including Shinjuku and Shibuya are modelled down to their underground platforms, visible through an x-ray view. Only six lines have published timetables; the author says so, and draws the other 141 thinner.
