Visual representation of how to tag

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.

Tag Usage
Primary classification (required)
railway=rail
railway=subway
railway=narrow_gauge
railway=preserved
railway=disused
railway=abandoned
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=1
For railway lines that are not broad gauge, tag the section with the relevant gauge specified in meters.

Common gauges are 1, .762 and .61m. Resource: IRFCA FAQ-Gauge

Secondary classification
rail=main
rail=branch
rail=commuter
rail=freight
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
rail:tracks=3
Use if a segment represents multiple parallel railway tracks of the same classification
Administrative
operator=IR
+IR:zone=SR:MAS
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, Erail.in-Station Codes

Maximum section speed (kmph)
maxspeed=40
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
service=spur
service=siding
service=yard
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.
Traction
electrified=contact_line
Use for electrified sections
Bridges and tunnels
bridge=yes
tunnel=yes
+ref=B23
+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)
railway=level_crossing
railway=crossing
+ref=LC3
+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.
Historical
date:start=1852
date:end=1987
date:converted=1995
date:doubled=2002
date:electrified=2003
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)
railway=station
railway=halt
railway=freight_station
railway=service_station
+name=Nagpur
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'. 'freight_station' are for facilities where only freight movement takes place. 'service_station' is used for location that are used for servicing of the rolling stock like Locomotive sheds, Carriage sheds etc.

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

Reference code
ref=MAS
ref=ABC:1
ref=ABC:2;3
Official station code used by the railways in ALLCAPS. If there are multiple station nodes to show different platforms, indicate the platform number by separating it with a colon. Only the primary station node needs to have a name=* tag, not required for the other station nodes. Use semicolon to separate multiple platform numbers.
Secondary classification
station=primary_terminal
station=secondary_terminal
station=commuter_station
station=junction
station=abandoned
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.
is_in=Chennai
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
