We celebrate high speeds. We rarely celebrate controlled deceleration . rdso technical pamphlet g-73
G-73 doesn’t just calculate brake distance; it mathematically accounts for loco pilot reaction time (approx. 1.5 to 2 seconds). At 130 km/h, in that blink of an eye, the train travels ~70 meters. G-73 ensures the brake cylinders are sized to compensate for this human delay. in that blink of an eye
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. rdso technical pamphlet g-73
