METHOD OF LOCKING OF RAIL VEHICLE BRAKE CONTROL DEVICES Russian patent published in 2007 - IPC B61H13/02 B60T15/18 

FIELD: railway transport; brake systems.

SUBSTANCE: method comes to isolation of control devices by means of disconnecting components in left control station and connecting with proper main lines in control station set into operation.

Provision is made in left control station for reduction of adequate tap of driver's brake valve and simultaneous isolation of auxiliary brake valve from like main line by adequate of three-way locking unit by means of switch-handle. Clearing of control devices in control station set into operation is effected by discrete setting of three-way locking unit to isolate similar tap of driver's brake valve and communicating simultaneously auxiliary brake with like main line. Input unions of three-way locking units are connected with taps of driver's brake valve connected with supply main line. Opposite input unions of three-way locking units are connected with main line of auxiliary brake. Output unions of three-way locking units are connected with output taps of auxiliary brake valve.
