| Feature | Underframe-Mounted (Pre-G-73) | Bogie-Mounted (Per G-73) | |---------|-------------------------------|---------------------------| | Brake cylinder location | Under wagon floor | On bogie transom | | Force transmission | By rods and shafts (subject to slack) | Direct via levers to wheels | | Bogie change time | 4–5 hours (brake rods must be dismantled) | 45 minutes (only hoses uncoupled) | | Synchronization between axles | Poor (long linkages) | Excellent (short, stiff linkage) | | Empty-load device | Separate underframe valve | Integrated on bogie | | Failure rate (brake binding) | High (due to distorted rods) | Very low |
