Introduction

Intermediate stations are built on single-track and double-track railway lines. In addition to the operations usually performed at junctions and overtaking points, at intermediate stations, passengers are also served, loaded, unloaded and stored cargo, baggage and mail; shunting operations to detach and trail cars to prefabricated trains and weigh cars; maintenance of access roads; paperwork.

With large cargo turnover, intermediate stations form sending routes or groups for stepped routes.

Intermediate stations are common, support and for non-stop crossing of trains; location of POP - longitudinal, semi-longitudinal and transverse types.

The nature of the work of intermediate stations is determined by the organization of the passage of trains of various categories and the maintenance of prefabricated and export trains with which loading and unloading cars arrive (or leave).

Shunting work on servicing cargo points is carried out by special shunting locomotives assigned to the station, and in some cases by train.

Development of a non-large-scale layout of the station in the axes of the tracks

In the course of further development of the non-large-scale station diagram, the following shall be shown:

- placement of tracks, arrows, passenger and cargo devices;

- distances between axes of adjacent tracks;

- track numbers and their specialization ;

- numbers of switches and marks of their crosses (switches with cross mark 1/11 are conventionally shown in a circle);

- type of rails;

- input and output signals;

- limit columns;

- direction of trains movement on approaches.

Switch necks of intermediate stations shall provide:

- isolation of shunting work on the exhaust line from the reception and departure of transit trains;

- simultaneous reception of trains with additional approaches with reception and departure of trains of the main direction;

- possibility of arrangement on double-track lines at both ends of the station of control exits between the main tracks. First of all, two dispatching exits directed in different directions (one at each end of the station) should be designed so that passenger trains from both directions are received to the passenger building;

- if possible, access from loading and unloading tracks to the main track in both directions should be provided (in case of justification) without rearrangement of trains, with mandatory construction of safety dead ends.

Conclusion

In the course work, a project of a new intermediate station was developed. The following work was performed during the design:

1. In accordance with the necessary requirements and based on the method of expert assessments, the type of intermediate station was chosen. For the selected type, its non-large-scale scheme was developed with the application of basic devices and structures.

2. The station plan was built on a scale of 1:2000, on which the passenger building, passenger service devices, limit columns, entrance and exit traffic lights were placed, tracks and devices for freight transport were designed, all tracks and switches were numbered.

3. Coordinates of centers of switches, stops of dead ends, input and output traffic lights, edges of passenger platforms, limit columns are specified. The axis of the passenger building is applied.

4. Lists of tracks, switches, buildings and structures have been compiled.

5. Profiles are made - longitudinal along the axis of the 1st main path and transverse at the point of section a-b.

6. With the help of computers, the scope of work for filling the roadbed was calculated. An estimate for the performance of work on enlarged meters was compiled.
