Behold the NODE
Using the new opportunities of the after-repair control the Volga Railway is able to take orders from the adjacent lines.
In the Volga Railway railcar depot Anisovka the comprehensive diagnostic system COMPACS®-EXPRESS-TR3 has been implemented.
So far the only one in the network system, intended for AC trains, has already studied the first overhauled suburban electric trains.
"The three sections of the electric train ED9M, which passed TR3, were brought into the specially equipped ways where the equipment operation was fully simulated in real time as if the stock moved by rails. It took COMPACS®-EXPRESS-TR3 a few minutes to reveal deficiencies. In the motor car – an underestimated time to lift a trolley, and in the trailing car – a disconnected power to the automatic locking doors. Mechanics immediately began to correct the deficiencies,"- says the head of the railcar depot Anisovka Sergei Kazanov.
COMPACS®-EXPRESS-TR3 allows to check all the electric systems of the train.
A monitor displays data concerning the operation of the machinist’s crane, pneumatic pipelines and air diffusers, brake cylinders, spare tank and compressor, wheel motor units, pneumatic door drives and pantograph.
"It is easy to detect the circuits in the compressor, heaters, contactors of the motor and trailer cars, to discover the brake system leakage," - says the railcar depot Anisovka technician Sergey Buyanov.
The new system not only speeds up an indispensable after-repair testing of the rolling stock, but also allows to output the train on the line without any defects.
"Previously, the workers had to check approximately the quality of the electric trains, examining the crucial nodes and parts. Presently this is the matter of the equipment concern. It admitted to eliminate the human factor, thereby ensuring 100% quality of repair", - says Sergey Buyanov.
"However, due to this system the road is able to take repair orders for electric trains from other routes," - said Sergey Kazanov.
