Railway lines

Note: This page is outdated and requires a review

Railway lines are mapped as ways and most railway lines can be easily mapped or traced using satellite imagery. These tags define the attributes for these railroad ways. A large part of the information required for these tags is already available on various sources on the internet. Also see OpenRailwayMap/Tagging

Tag Usage
Primary classification (required)
Use 'rail' for broad gauge sections and 'narrow_gauge' for smaller gauges including metre gauge. 'subway' is used for dedicated metro corridors (Rapid transit) in cities where other kinds of rail traffic is prohibited. 'preserved' are railway lines that are primarily used to run heritage or tourism services. 'disused' are for sections that are no longer in use while 'abandoned' are for historical alignments which no longer exists.
Gauge (metre)
gauge=1676 (Broad Gauge)
For railway lines that are not broad gauge, tag the section with the relevant gauge specified in mm.

Common gauges are 1676, 1000, 762 and 610. Resource: IRFCA FAQ-Gauge

Secondary classification
secondary classification to distinguish between railway=rail segments. Choose an appropriate tag in descending order of priority. . 'heritage' sections are historical sections that are run primarily for the purpose of tourism. Not required if the line carries mixed traffic.
Parallel tracks
Use if a segment represents multiple parallel railway tracks of the same classification
Specifies the operator of the railway section. Should be IR (Indian Railways) unless operated by others (Port Trusts etc)

For zone, use the official zonal abbreivation seperated by the station code of the divisonal headquarters of the division under whose jurisdiciton it falls (IR:zone=ZONE_CODE:DIVISION_HQ_CODE). Use ALLCAPS for the codes. Resource: wikipedia:Indian_Railways#Railway_zones, Codes

Maximum section speed (kmph)
Default is considered as 80kmph when not tagged. Useful for computing travel time between stations and locating high speed railway sections.

Keep minimum track segment length to atleast the distance between two stations, do not split the rail segments unnecessarily.

Service track classification
Used for tracks not used for mainline operations. 'siding' and 'yard' include lines for stabling coaches, pit lines, maintenance tracks and for shunting operations. 'spur's are small branches of tracks used by industries. These lines have low priority on the map.
Use for electrified sections
Bridges and tunnels
+name=Krishna Bridge
For tagging segments that are bridges or tunnels. Can be used in conjunction with 'name' and 'ref' to indicate the official bridge or tunnel number
Level crossing (node)
+name=NV Colony
For tagging nodes that intersect with a road, 'level_crossing' are manned and have gates. other unmanned crossings can be tagged just 'crossing'. Can be used with the name=* and ref=* to label it.
This tag stores historical information when a track segment was constructed or abandoned. You might need to refer to historical maps or records for this information

Railway Stations

Railway stations are mapped as nodes and require a more presicion source for mapping like GPS track or high resolution Yahoo imagery. Its also possible to distinguish major stations on Landsat imagery due to their larger size. Smaller stations serving villages can be mapped as the closest point of the railway line to the place, usually having a road leading from it.

The railway tracks usually split into multiple ways while nearing major stations having multiple platforms. If possible these tracks can be mapped seperately, one for each platform. However only the platform serving the the primary station entrance needs to be tagged in detail and must have the name=* tag. The station nodes for the other platforms need to have only railway=station and a ref=STATION_CODE:PF# to indicate the platform number, see below for usage.

Tag Description
Primary classification (required)
Use 'station' for fully functional railway stations, 'halt' for stations with basic infrastrucure without regular scheduled services. This would usually be indicated in the railway timetable with a postfix 'H'.

While naming, use the same name that appears on the timetable, without 'Railway Station' or 'RS'.

Reference code
Official station code used by the railways in ALLCAPS.
Secondary classification
For use to classify railway=station nodes. For cities with more than one station where train services terminate, tag the primary station with 'primary_terminal' and the other terminal stations with 'secondary_terminal'. Some cities may have two primary terminals like Delhi (Delhi-DLI and New Delhi-NDLS) or Mumbai (Mumbai Central-BCT and Mumbai CST), since they terminate trains coming from different systems. 'commuter_station' are those which service only commuter or suburban trains. 'junction' are stations between major cities from where railway lines branch out. Junction stations serve as transiting or reversing points and generally larger in size with more amenities.
Used for grouping multiple stations that serve the same city.

The Indian railways has a technical and commercial classification scheme for stations nin the network source:IRFCA source:WR

Class Passenger earning per annum Station type Platform type
A1 Rs 50 crore + non suburban High
A Rs 6-50 crore non suburban High
B Rs 3-6 crore non suburban Low
C n/a Suburban (Commuter) High
D Rs 0.5-3 crore non suburban Low
E Rs 0.5 crore non suburban Low
F n/a halt station Rail
