PECULIARITIES OF PNEUMATIC BRAKE CONTROL ON PLAIN SWITCHING OF AIR BRAKE VALVES WHEN DRIVING TRAINS ON MOUNTAINOUS areas
The analysis of the action of the locomotive crew and the work of the technical means of the heavy-weight train, providing braking on the downhill section of the railway track, is given. Multiple locomotive traction with axial control and combined braking is used for this purpose. Positive properties of modern braking equipment providing safe movement of trains with increased mass are expressed. On the basis of the conducted experimental tests it is possible to improve the quality indicators of the operation of trains on the mountainous profile of the track by reducing the value of the charging pressure and the cancellation of the train downtime when switching the modes of air distributors of the cargo type to the mountainous mode.
