Braking systems of trains

United train, formed of two freight trains, the total aggregate weight of more than 6 to 12 tons and the number of axes 400-540 are admitted to trading in the normal operation only with the combined braking highway. Locomotives must be equipped with a crane driver with the position of VA and signaling device with sensor breakage train number 418. With a total number of axles connected trains of up to 400 must include a pneumatic brake control and synchronization pull off on the second locomotive (the presence of a second locomotive crane operator's position with VA and break with a sensor alarm number 418 in this case is not required).

Combining freight trains while maintaining the autonomy of brake lines shall be permitted only as a measure to reduce train delays in the provision of "windows" for track repair and construction, as well as significant intervals of trains due to natural disasters, accidents, etc. They pass to the double-track sections should be carried out on a temporary single-track ferrying and one or two lying ahead overtake without crossing with passenger trains, and on single track lines, the movement of trains can be incorporated within the site, including the repaired block.
