At sidings, passing points and stations, the tracks are limited by limit posts and signals. The limit columns indicate the place beyond which rolling stock cannot be installed on the track in the direction of the turnout. This ensures traffic safety. So, the tail of the train is on the way A- B must stand so that the train coming from A(or from B to A), one could easily take the path A - B(Fig. 163, A). This is possible if the distance b- With enough to pass along the way A- IN the widest carriage or locomotive, taking into account vibrations during movement. Distances b - With And With- d according to the PTE they are equal to 2050 mm, which corresponds to a distance between tracks of 4100 mm; on existing tracks, a distance of 3810 mm is allowed; on transfer tracks with a narrowed inter-track, limit posts are installed where the inter-track width is 3600 mm. With a car width of 3600 mm, the free gap for safe passage of cars will be 4100-3600 = 500 mm. If these minimum distances are observed, depending on the location of the converging paths, the distance from the center of the turnouts to the limit posts will be different:
the limit column is located between straight converging paths (Fig. 163, b)

limit column of a wool switch (Fig. 160, a); output signals - at each track or group of tracks intended for the departure of a train, in front of the locomotive parking area. Signals located in between tracks are placed taking into account the size of the approaching buildings, mast traffic lights - at a distance of 2450 mm from the track axis. Distances to signals are calculated using the same formulas as to the limit columns (Tables 5 and 6).
When equipping switches and signals with electrical centralization, station tracks and necks are divided into isolated sections. Insulating joints are located at a distance of at least 3.5 m from the limit posts away from the station. Between these joints and the tail of the crosspiece it is necessary to lay non-standard rail houses. In order to be able to lay standard cuttings behind the tail of the crosspiece (minimum cutting is 6.25 m and, as an exception in difficult conditions, 4.5 m), the calculated distance between the limit column and the center of the switch is increased accordingly, while maintaining the specified useful track length.
output signal and limit column at the opposite end of the path (on the path 5 signal I 5 and the limit column at the turnout 15; on a way 2 signal H 2 and the limit column at the turnout 2) . The useful length of the double-acting track (main track I) differs in directions (for direction B - the distance between the limit column at the turnout 4, but not 2 and signal H 1 for the direction to A - between the limit column at the turnout 5 and signal N 1 ) ;
limit column and anti-hair turnout (path 7 - from the limit column at the turnout 19 to front frame rail joint arrows 14) ;

anti-hair arrow or signal and dead-end path stop (exhaust path 4 - from shunting signal M 4 all the way, if there is no signal - from the front joint of the frame rail at the turnout 7 all the way).
To determine the need for superstructure materials, calculate full length station tracks. It is important not to miss any elements of the path and not to count them twice. Counting is usually carried out along the track axes from the centers of the turnouts. Since turnouts in sets are supplied separately, after calculating the total length of the station tracks, the total length of all turnouts is subtracted from it. Main paths are not included in the calculation. We will show how to calculate the total length of station tracks in Fig. 166:
Separately calculate the length of the ramps 11 -3,1 -7 and 17 -21. The access road is taken into account if its construction is included in the project. If rails of different types are laid at a station, the total length is calculated for each type separately.
The useful length of receiving and departure tracks for freight traffic (1250, 1050 and 850 m) is taken in accordance with the length of trains planned for a given line in the tenth year of operation, taking into account the unified length of trains on neighboring lines. On lines with high traffic load, with an appropriate feasibility study, receiving and departure tracks can be adopted with a larger useful length (one and a half or double). This will make it possible to organize the driving of long trains and connected trains. Useful track lengths for the reception and departure of various types of transfer trains, freight fronts, etc. are established depending on the freight turnover, technological
whom the work process and local conditions. The useful length of tracks intended to carry only passenger trains with parking must correspond to the longest length of the latter accepted for use in the fifth year of operation, and the length of passenger platforms up to 500 m (and those serving only suburban traffic - 300 m). The useful length of marshalling tracks for the accumulation and formation of single-group trains, as well as the connection of parts of group trains, is taken depending on the length of their trains, and at marshalling stations it is recommended to increase the length of the tracks by at least 10%. The useful length of safety dead ends is at least 50 m, the main exhaust tracks at district and marshalling stations are equal to the full length of the freight train, and at intermediate stations - at least half of it (in the first stage - at least 200 m).

Answer.
A track sign is a permanent indicator of the profile and length of railway lines.
Signal sign - a conventional visible sign (a limit column, a sign indicating the boundaries of a railway station, blowing a whistle, turning off and on the current, etc.), with the help of which an order is given to a certain category of railway transport workers
Special track signs - boundaries of the railway right-of-way, arrow number indicator, passenger building axis sign, signs on linear track buildings, benchmarks of the beginning and end of circular curves, as well as the beginning, middle and end of transition curves, hidden structures of the roadbed, the highest water horizon and maximum wave height
Signal signs are installed, respectively, by the owner of the infrastructure, the owner of the non-public railway track on the right side in the direction of movement, and track signs - on the right side according to the number of kilometers at a distance of at least 3100 mm from the axis of the outer railway track.
In excavations (except rocky ones) and at the exits from them, track and signal signs are installed, respectively, by the owner of the infrastructure, the owner of the non-public railway track outside the ditches and chutes on the field side. In heavily drifted excavations and at the exits from them (within up to 100 m), these signs are installed at a distance of at least 5700 mm from the axis of the outer railway track. The list of such excavations is established, respectively, by the owner of the infrastructure, the owner of the non-public railway tracks. In electrified areas, signal and route signs can be installed on contact network supports, except for those supports on which traffic light heads, complete transformer substations, contact network disconnectors and arresters are installed.
Limit columns are installed in the middle of the intertrack in the place where the distance between the axes of converging railway tracks is 4100 mm. On existing station railway tracks, which are not used by railway rolling stock built to gauge T, it is allowed to maintain a distance of 3810 mm. On transshipment railway tracks with a narrowed inter-track, limit posts are installed in the place where the width of the inter-track reaches 3600 mm.
On curved sections of the railway track, these distances must be increased in accordance with the rules and regulations.
Signal, wayfinding and special waymarks must comply with the rules and regulations.
13. Installation and purpose of the limit column.
Answer.
Limit bars indicate the boundary within which rolling stock can be located on a given track without violating the safety of traffic on the adjacent track.
Limit posts for station tracks (except for receiving and departure ones equipped with electric rail circuits) are installed in the middle of the track in the place where the distance between the axes of the tracks diverging from the center of the switch is equal to 4100 mm . On existing station tracks, which are not used by rolling stock built according to gauge T, it is allowed to keep this distance equal until reconstruction 3810 mm.
Setting limit bars carried out behind the turnout cross in a sharp corner. Limit column determines the gauge of the railway track or indicates the boundary within which rolling stock can be located on a given track without interfering with the safety of traffic on the adjacent track.
Limit posts for station tracks (except for receiving and departure ones equipped with electric rail circuits) are installed in the middle of the track in the place where the distance between the axes of the tracks diverging from the center of the switch is equal to 4.1 m(from the limit column to the axis of the straight path R= 2.05). On existing station tracks, which are not used by rolling stock built to gauge T, it is permitted to install limit posts at a distance of 3.81 m (before reconstruction).
The distance from the translation center to the limit column installed between two straight paths diverging in different directions will be R·ctg(α/2) (or rounded 4.1ctg α), but after branching the paths most often run parallel to each other (Fig. 1, a). In this case, the distance to the limit column depends not only on the brand of the translation cross, but also on the width of the interpath and the radius of the curve.
Rice. 1 - Schemes for installing limit columns
The distance from the limit column to the axis of the path in the curve should be R+ ∆, where ∆ is the increase in the overall distance to structures located on the inside of the curves (with R= 200 m it is equal to 0.18 m, with R= 300 m - 0.12 m). The value of the angle β at e > 2R+ ∆ is determined from the equality
Distance from translation center to limit column
The installation of limit columns when the turnout has a conversion curve (Fig. 1, b) is carried out on the basis of the following formulas:
where ∆ n is the increase in the overall distance to structures located on the outside of the curves.
When installing limit posts on receiving and departure tracks equipped with electric rail circuits, insulating joints must be placed at a distance of 3.5 m behind the limit post (taking into account the maximum length of the protruding part of the rolling stock in relation to the outer axis). In order to use standard cuttings (12.5 and 6.25 m) on the section of the track from the end of the cross to the insulating joint, it is recommended to slightly increase the distance from the center of the transfer to the limit column compared to the calculated dimensional conditions.

Revision of the document taking into account
changes and additions prepared
JSC "Kodeks"
Paths at separate points are limited by limit posts and traffic lights. A limit column is installed between converging tracks and indicates the boundary of the track beyond which no parts of the rolling stock should go. Rolling stock located within the track, limited by the limit posts, should not violate the clearances for movement along the adjacent track. The limit column is installed in the middle of the intertrack in the place where its width reaches 4.10 m between the axes of adjacent tracks. Accordingly, to install a limit column, it is necessary to ensure a distance of not 2.05 from the axis of each path to the vertical axis of the limit column.
intermediate station switch
For a 1/11 grade turnout, the distance from the center of the turnout to the limit column is 46.86 m.
The placement of traffic lights is one of the most important factors in the design of an intermediate station. Depending on the track development of the station, track specialization and operating technology, the following signals are installed at the station:
Entrance – enclosing the station from the side of the tracks;
Weekends - allowing or prohibiting the train to go on a stretch;
Route - allowing or prohibiting the train to proceed from one area of the station to another;
Maneuvering – allowing or prohibiting maneuvers.
Entrance traffic lights are installed in front of the entrance switch, at a distance of 50 m for diesel traction, and at least 300 m for electric traction. This distance is measured from the beginning of the points when laying the turnout anti-wool and from the limit column - if the turnout is made of wool. For given conditions, entrance traffic lights are located.
H at a distance of 50m in front of switch 2, taking into account the distance from the beginning of the points to the center of the switch:
Lch=50+11.25=61.25m;
Traffic light N:
Ln=50+12.42=62.42m.
When installing exit, route and shunting traffic lights, there are three methods depending on the installation location.
1. The traffic light is located in the same inter-path with the limit post fencing the path. In this case, the traffic light is located in the place where the width between the tracks is sufficient for its installation. This width depends on the design of the traffic light and, accordingly, its overall dimensions. Thus, the largest track-to-path width of 5.2 m is required for installing mast-mounted traffic lights on reinforced concrete or metal masts with stairs. The smallest width – 4.2 m – for installing a dwarf single traffic light. For practical purposes, the signal distance is taken lsign=56m according to the recommendations. The following traffic lights are installed using this method: Ch3, m8, m6, N4, Chm2, Chm4.
2. The traffic light is located at different interpaths with a limit column. limiting the length of the path enclosed by a traffic light. In this case, the traffic light is located in an alignment with an iso-joint, i.e. at a distance of 3.5 m from the limit post towards the track. Traffic lights are installed in this way: Ch1a, Nm3, m3, m10, m12, m4, m5, HI, N2.
3. The traffic light is installed in front of the turnout switch in the alignment with the joint of the frame rail, i.e. at a distance a from the center of the turnout. Traffic lights are located at a distance of Chm1-15.19m from TsSP 15; Nm1a - 14.02 m from DSP 7; m1 and m2 – 15.42 from DSP 3 and 6, respectively.
