In the process of railway transportation, in addition to train operation, in order to organize or disassemble trains, take and deliver vehicles, etc., transferring locomotives and vehicles on the line belongs to shunting work.

2. The shunting work at the station is classified by technical equipment?

According to the classification of technical equipment, it can be divided into traction line shunting and hump shunting. Traction shunting, also called plane shunting, is the most basic shunting operation mode.

At present, most technical stations in China's railways still use outgoing lines as the main shunting equipment. Even in the station where hump shunting equipment is used, the marshalling operation at the tail of hump, the transition and change of trains, the pick-up and delivery of cars and the pick-up of trailers are carried out on the lead-out line.

In the shunting operation of most intermediate stations, most pick-up trains are powered by locomotives, and there is no intermediate station to pull wires.

1, railway train

Railway trains can be divided into freight cars and passenger cars according to their load capacity, and there are mixed passenger and freight cars.

2. Diversion

Shunting can be divided into lead-out shunting and hump shunting according to the equipment used and the operation method.

(1), leading to shunting.

Traction line shunting includes push shunting and sliding shunting. Push shunting is to transfer the vehicle from one lane to another with a locomotive, without picking up the vehicle during the journey. The locomotive pushes the train to a certain speed for slip shunting, and lifts the hook of the planned train set during the journey, so that the picked-up train set can slip to the designated place.

(2), hump shunting

Using hump to decompose trains usually includes four links:

(1) Trailer: The locomotive goes to the destination or departure place with the trailer train. When the arrival yard or the departure yard is parallel to the yard, it also includes the pulling operation of pulling the train to the arrival yard or pushing the peak line before the rush hour.

② Push the peak: the locomotive pushes the train to the peak. When the double-push single-slip operation mode is adopted, it also includes the pre-push operation of the train on the pre-peak signal.

(3) Car-slipping: the locomotive continuously pushes the train, so that the picked train sets can slip over the peak to the designated line of the yard.

④ Closing: After several consecutive trains break down, the locomotive will close the vehicles on the inner line of the yard at a lower peak, creating conditions for the hump to continue to slip.
