| ELECTROPNEUMATIC DEVICE FOR RAILROAD ROLLING STOCK AUTOMATIC STOP |
| Typical electropneumatic device for railroad rolling stock automatic stop includes a bracket, a pneumatic master body with a housing and a spring-controlled movable partition, an air valve, a contact group, a pressing unit. In addition, the device includes an electropneumatic valve linked with an audible alarm system. The said electropneumatic valve has a cavity in which the following parts are placed: a cut-off valve cutting off a conduit connected with a feed manifold and a timer compartment; a lock with a housing, a key and a contact group; a braking body with a housing and a conduit connected with a braking system manifold.
Several modifications of the device are also described.
In the first modification of the device, the said lock is provided with a cut-off valve linked with a key; the cut-off valve closes the passages made in the lock housing which connect the lock with the electropneumatic valve, the timer compartment and the feed manifold. |

| A METHOD TO SUPPLY CURRENT TO ROLLING STOCK AT SUBWAY DEPOT, AND THE WAGON TO IMPLEMENT THE METHOD |
| Under the new technology, contact fingers are placed in boxes containing safety devices. These safety devices, located on both sides of a wagon under its body above the current trolley (collector) level, are connected in series and prevent access to certain contact fingers. To test workability, the safety device installed in the respective box is removed... |

| METHOD OF FINDING DAMAGED SEGMENT OF CABLE WITH METALLIC COMPONENTS |
| In the proposed method, the impulse receiver accepts the signal reflected from the damaged section, rather than induced impulse. The point of damage is determined reference to position of the monitoring impulse source, when the marks of the monitoring impulse and the signal reflected from the damage point coincide on the receiver display. |
