With Vande Bharat trains pushing 180 km/h, G-73 is currently under revision. The next version (G-73 Rev. 3 likely) will likely mandate brakes—where the brake command travels at near light speed, not at the speed of air through a pipe.
A loaded coach weighs 3x more than an empty one. If you apply the same braking pressure to both, the empty coach will skid (flat wheels) and the heavy one won’t stop. G-73 mandates load-compensated braking —a brilliant pneumatic logic that senses weight and adjusts brake force automatically.
