Let us take you to a repair depot for high speed trains Sapsan.
That trolley is a flaw detector Sapfir.
Some of the words are misspelt on this sign.
The Sapfir’s control panel. It features WiFi.
This vehicle is used to move trains.
A top view of the Sapfir.
A test axis.
“Number of seats: 66”.
The train is very comfortable and has a smooth ride due to its powerful shock absorbers.
Those are axes with brake disks.
Brake disks of this axis are placed on the outer side of the wheel.
This is where axes are stored. Each axis is marked with a sticker. Green color means it is ready for use while orange means it is defective.
They haven’t decided yet what to do with defective axes because remelting is expensive and fixing them is too risky (the train’s maximum speed is 270 km/h!).
This device is called Shuttle. It has a weight of 700 kg and features a 2 hp engine.
The Shuttle’s control panel has a touch screen.
Another train has just arrived.
