29.09.2013 Aigio railway station. Ζ14 15071. Also, some explanations of how the brake-system works, summarised.

Brake-system:

Brake-cylinder + Horizontal-balancers. The air-cylinder takes the air - already didstributed by the ditributor from the air-reservoir (when wagon is stable) / and or by the air-brake pipes from the other rolling-stock / and or locomotive, and moves the rods (Bremsgestänge), which their ends press the vertical balancers (above the axle of the wheelset) that press the brakes on the wheel-rim.

Τhe air-reservoir stores the air, such as to be used by the distributor, when the wagon is stable.

Τhe distributor "does the job' that is above-mentioned, and is connected withe brake-releaser, so as the brakes may be released manually, in cases of need / and or shunting.

The brake-leavers of 2 types:
a. The one that controls how much Air is needed for braking, i.e. more, when wagon is connected to passenger trains - as the speeed is high, and less, when wagon is connected for freight trains - as the speed is low.
b. The one that controls, when is needed the Air-reservoir to be empty (leer) or full (beladen).

The hand-brake, releases the brakes, during shunting-operations.

Thanx

Dimitris
