That's why you should be doing a brake continuity check before departing… (Of course that's not entirely foolproof, either, and there have been accidents caused e.g. by a lack of braking power because the brake pipe wasn't fully connected throughout the full train.)
- KptMarchewa 3y agoYeah, on Polish railways there's always brake check on the last carriage. > (Of course that's not entirely foolproof, either, and there have been accidents caused e.g. by a lack of braking power because the brake pipe wasn't fully connected throughout the full train.) Can you specify what you mean? If the pipe wasn't properly connected, it shouldn't start at all, because the system needs pressure to release the brakes.

These pneumatic systems leak. You're not allowed to park a train for longer than 24h in Germany if it is purely secured with air pressure for that reason - if it's a particularly bad composition, you seriously risk having no pressure anywhere in the system by that time, and thus no brakes being applied.
- CapstanRoller 3y agoAren't train brake systems safe by default? I thought air pressures released the brakes, not activated them.
