This page intends to help organize efforts to map railways in the United States. Note that in the United States, because of US English, "railroad" is frequently used across many contexts (not simply OSM) in preference to "railway" (which is more British English).

Due to recent wiki and associated software upgrades, map details are not-quite-correct. One-click fix: hover over the map's upper-right layers stack icon and click "Transport Map" to see the USA at national scale; zoom in to see tracks and stations. As this is a "live" slippy map, it can be panned and zoomed; zoom in (at least two zoom levels) to see rail infrastructure networks.

Editing Railroads starting from TIGER data

Like the TIGER highways import, hundreds of thousands of miles of railroad tracks (both active and abandoned) have been imported from (federal government, public domain, mid-2000s) TIGER data and share problems similar to highways, like disconnected segments, wrong tagging, missing bridges and crossings and positions that are frequently misaligned by significant distances. So a review is necessary for rail, just as it is for highways. Sources to improve these data might include Bing or DigitalGlobe imagery, a recent state government Department of Transportation rail document, a road/rail crossing spreadsheet and/or your own "on the ground" observations. Another source is bts.gov (see below for link) with various rail layers that OSM can use, often authoritatively yielding subdivision names, rail ownership and operator data. Yet another official source is the FRA Safety Map. Such review might include following an entire rail "line" of less-reviewed TIGER rail (tiger:reviewed=no) from one end to the other, paying particular attention to:

  • accurate alignment (compared to recent aerial or satellite imagery),
  • multiple tracks (each mapped individually, preferably not with tracks=#),
  • tracks tagged service=crossover between parallel mainlines, branches and industrial track,
  • tracks which make up yards, usually tagged service=yard,
  • bridges (bridge=yes, layer=1) and tunnels (tunnel=yes, layer=-1), where they exist,
  • assuring that at-grade road/rail crossings are an actual intersecting node tagged railway=level_crossing and
  • assuring that at-grade pedestrian/rail crossings are an actual intersecting node tagged railway=crossing.

If a tiger:reviewed=no tag exists and you "reviewed" the rail (e.g. comparing against aerial/satellite imagery and better aligning where necessary, assuring tags are all correct...), delete this tag — don't change it to the superfluous tiger:reviewed=yes or something like tiger:reviewed=aerial.

Now you might gather identically named rail segments (often ways tagged railway=rail) as members into a named relation tagged type=route, route=railway and name=Name of Subdivision or Line. Values of elements tagged railway=* and name=* should be identical or nearly so: minor name=* value differences (like suffixed with MT1 and MT2 to denote two main tracks) sorts itself out now; slight variations in name=* allows multiple OSM volunteers to buffer edits as we more correctly tag, name and organize. Be aware of private/corporate rail map data being copyrighted, don't copy these into OSM. Some good news, [1] (links to arcgis.com) offers map browsing of rail data displaying owner, trackage rights (sometimes shared among a surprisingly large number of operators) and subdivision names, these geo data are freely available to OSM in the public domain by the federal government, while rail professionals consider them authoritative. Better operator=* and owner=* tags (absent from TIGER import) continue to improve, especially as name=* tags from TIGER properly become one or both of these two tags and subdivision names are discovered and entered as correct name=* tags. Please do not prefix subdivision names with the operator unless a nearby identically-named subdivision benefits from disambiguation by doing so. For example, there are two "Dallas Subdivision" relations in Texas, but because of their proximity and ease with which they may be confused, one is named "UP Dallas Subdivision" and the other is named "KCS Dallas Subdivision." (Good practice has also properly set operator=* on both). Otherwise, continue to migrate the operator (e.g. UP, BNSF, CSX, NS...) to the operator=* tag, removing it from the name=* tag unless the above "proximity exception" exists, then prefix the name=* tag with an operator abbreviation as in that example. It is emerging in North American rail tagging to use the reporting_marks=* tag to denote the train operator(s), although the infrastructure operator operator=* or even a shortened-name version of this operator:short=* certainly can be added to a way tagged railway=rail. JOSM has an excellent relation editor dialog window which displays connectivity of contiguous segments, please remember to click the Sort button before you close the relation editor dialog window of a route=railway.

These steps (visual layer review, discovery of and tagging of subdivision name, proper alignment and tagging, including usage=* and operator=*, creating a named route=railway relation...) lead toward excellent OSM data and render well in OpenRailwayMap (ORM) after approximately 24 hours. Definitive ORM tagging documentation is found here, however, see below, especially rail structure. These are USA-specific summary guidelines for rail tagging from originally TIGER data, here are some helpful additional North American rail tagging conventions.

For a starting point of "unreviewed TIGER rail in a given state" try this Overpass Turbo query (in this case, Rhode Island, this is easily edited to be another state or county). For some states, this is (initially) too much data and the query will run short of OT server compute cycles, memory or timeout. First try to increase the timeout value, then try to restrict the query to a (unique) county level, e.g. "Colusa County." However, it is important to note that many routes were already reviewed long ago, but tiger:reviewed=no was not removed.

As of 2022, TIGER Review of rail continues, though much still needs doing: a (compromise) estimated value is "about 75% complete," with easily tens of thousands of miles of rail yet to review. After TIGER Review of a rail line (alignment, proper tags, deleting tiger:reviewed=no so others know, placing track segments into a route=railway relation...), it can be helpful to wiki document this completion. This is done in "infrastructure tables" of state-level /Railroads wikis: often these are color-coded (red, yellow, green=done or almost done) for an at-a-glance status of TIGER Review progress in a given state (see State projects below).

Suggestions

To improve USA railroads in OSM:

  • Follow unreviewed TIGER rail along their length, comparing with your best data. This can be many things: a survey or GPS track, a state's Department of Transportation latest Rail Plan or crossing data, Bing or DigitalGlobe imagery, rail enthusiast lore OSM has permission to use or personal rail knowledge that is "on the ground verifiable."
  • Assemble identically named rail segments (not already gathered) into a named route=railway rail relation. And/or, improve these. It CAN be tedious to stitch them together properly! JOSM is the recommended editor as it has an excellent relation-editor window. Before uploading, please click the "sort relation" button.
  • Clean up yards using Bing or DigitalGlobe imagery or better knowledge, as well as tagging them with more of an ORM scheme. Currently yards are moderately correct, but need improvement from more-recent aerial or satellite imagery or real-world data newer than the mid-2000s TIGER import. Prior to 2020 and due to the vernacular of "yard" as the word is used in North American rail parlance, "yard" was tagged in OSM on a wide variety of rail facilities here. Going forward, better USA tagging should distinguish between a "yard" and a railway=service_station, the latter being "a railway station only used by railway employees." With ORM's tagging scheme (preferred), "yard" is "a railway station for freight, including yards that don't involve the loading or unloading of freight" (such as marshalling, classification, repair, washing of rolling stock, etc.) Please tag railway=service_station where this is a more correct semantic, even if this means changing what is now tagged railway=yard. If a polygon is tagged railway=yard, change this tag to landuse=railway and add a node tagged railway=service_station OR railway=yard to a node at the "logical center" of the station or yard, not a track way or a polygon way.

More work needs doing. Eventually, all named rail (not tagged service=*) should be in route=railway relations, whether active, disused or abandoned. USA railroads are not 100% there yet, but continue to approach this subgoal. Other frontiers are maxspeed=* and railway=signal tags, barely extant now. Should you take a look and decide to do so, MUCH here can use review and/or improvement, especially improving tagging, adding stations/stops/platforms and creating route_master relations to upgrade route=train passenger rail relations from public_transport:version=1 (v1) to v2. Thank you!

OSM Rail Structure in the USA

ORM documents tagging rail with three "levels" of route relations:

Railway line Railway route Train route (passenger rail)
route=tracks route=railway route=train or route=light_rail or route=subway or route=tram

However, in the USA, largely because of how our TIGER import entered rail, we skip collecting members into route=tracks relations and collect "physical railroad" elements (track members of railway=rail, railway=disused or railway=abandoned as infrastructure) directly into route=railway relations. These route=railway relations are equated with the USA's familiar named Subdivisions, Branches, Industrial Lines and railway=abandoned: contiguous rail segments with identical railway=*, name=*, operator=* and usage=* tags. ORM tagging suggests these be tagged with two relations, BOTH route=tracks AND route=railway. The route=tracks relation is an "extra syntax wrapper" we dismiss in the USA (and North America) rail, even as wider impact of not using route=tracks relations (on rendering, routing engines...) is not fully understood. However, many years of not using route=tracks in the USA appears to have had no ill effect on mapping (for example, in OpenRailwayMap) or routing of railways. In the early 2020s, it emerged more clearly that route=tracks relations are quite specific to Germany and how rail is "grouped" there (along with how rail is "grouped" using route=railway relations for specific purposes). This means that not using route=tracks relations in areas outside of Germany is correct, as long as it remains understood that the combination of route=tracks + route=railway relations means something specific to Germany, and that route=railway relations in Germany and route=railway relations outside of Germany mean something slightly different from one another. In Germany, route=railway relations have quite specific meaning, whereas elsewhere they are "generic groupings of rail, usually specific to how rail is aggregated in any given country's rail structure."

Not especially frequently, but enough to be documented here, collections of rail segments (tracks) into route=railway relations continues at another "level" as USA route=railway relations are themselves sometimes collected into super-relations. For example, the USA has a "Transcontinental" route=railway super-relation from Chicago to Los Angeles named Southern Transcon containing the eleven member route=railway relations that make up this route. We call this a "Major Mainline Rail," and there are others like it, such as Northern Transcon, from Chicago to Spokane. Newer "regional corridor" projects like Crescent Corridor and MidAmerica Corridor are also being included in OSM as "Major Mainline Rail."

Finally, reasonably common in the USA, especially long-distance / national trains and in urban areas as "commuter" rail (usually "heavy rail") and so-called "light rail" are passenger rail routes (route=train or route=light_rail or route=subway or route=tram).

So, in the USA, we largely express rail with these three "levels" of route relations:

Railway route "Aggregated" railway route (major mainline rail) Train route (passenger rail)
route=railway Several contiguous route=railway relations in a super-relation route=train or route=light_rail or route=subway or route=tram

This diverges from tagging as is done in Europe (especially Germany), since in the USA route=tracks relations are deliberately omitted; only route=railway relations exist. Pay attention to the direction of a way tagged railway=rail, as if this is expressed in harmony with the prevalent direction of travel on the way, such directional harmonization may continue to promote some downstream software continuing to work properly. For important further discussion, see the Discussion page.

Train routes

A train route is a route=train relation that describes the route of a train in regular passenger service. Its members include the stations/stops/platforms served by the train as well as the railways (ways also part of railway route relations) on which the train travels. Example United States train routes which are both in OSM and are wiki-documented include:

In the United States, Amtrak™ operates all passenger=international (serving Canada), passenger=national (nearly all are overnight), highspeed=yes and most passenger=regional (intrastate or interstate) train routes. Also, private operators emerge offering passenger=regional service (e.g. Virgin Trains USA, Brightline). More locally, many state Departments of Transportation (DOTs), Regional Transportation Authorities (RTAs), Municipal Transportation Districts (MTDs) and private operators offer passenger=suburban ("commuter"), passenger=urban (large-city scale "light rail"), and passenger=local (tram, monorail, people mover, some heritage trains...) train routes (Amtrak™ does not offer any of these three "more local" passenger services). Some passenger=regional train routes are DOT/RTA/MTD - Amtrak™ funding partnerships, so branding/ownership distinctions between Amtrak™ vs. DOTs/RTAs/MTDs and regional vs. suburban/commuter can blur. For example, what the California State Transportation Authority (CalSTA) calls "intercity" rail is what OSM calls "regional" rail. Likewise, CalSTA calls "regional" what OSM (here) calls "suburban" or "commuter" rail. The connotations of "urban" rail by both CalSTA and OSM are about the same. Your state may vary.

Tag train routes 160 - 1400 km (100 - 870 miles) in length passenger=regional, while passenger=suburban is for full-size (commuter, "heavy") passenger rail services shorter than 160 km (100 miles), usually not light_rail and never trams. (Two exceptions are Amtrak™ Hiawatha Service® and Hartford Line, both under 160 km, though tagged passenger=regional rather than passenger=suburban; Amtrak™ no longer categorizes its routes as suburban). Generally, tag railway=light_rail train routes as passenger=urban and street-running route=tram train routes as passenger=local. However, if a tram is a significant part of a wider-area network (especially as one or more of its stations serve as a hub to other passenger routes, like a bus route network), tag a tram at least passenger=local if not passenger=urban. If a tram or train route is tourism-oriented (usage=tourism on underlying infrastructure), consider tagging it passenger=local, or if it isn't a significant part of the local transportation network (e.g. it is only excursion- or entertainment-oriented), omit a passenger=* tag altogether. Short-distance train routes found at large airports, (frequently monorail or "automated people mover") linking terminals, rental car areas, long-term parking and especially wider-area transit networks are often tagged passenger=local. A transit network may have only a single railway=light_rail, railway=tram or railway=monorail train route, especially when complemented with bus routes.

About half of the USA's states (including all  Western states) have state /Railroads wikis, comprehensive train route sections are found at Level 1 titled "Passenger trains," see State projects below; a distinct trend is toward putting train routes into these state wikis. Many train routes are already in their state /Railroads wiki's "Passenger trains" section. For example, Caltrain, Los Angeles County Metro Rail, San Francisco's BART and San Diego Trolley (among others) are found in California/Railroads/Passenger.

Emerging both in the real world and in OSM are newer high-speed passenger=regional train routes, some public, some private: California High Speed Rail, RMRA, Texas Central Railway, Brightline West, others. These newer high-speed train routes are longer-term-future oriented, as they are either in early construction phases, remain in planning and/or are unfunded.

Projects

State (or commonwealth) projects

Used to describe stages of software development, "alpha" and "beta" here describe a quality assurance phase of statewide railroad data in OSM and completeness of their wiki in documenting those data. Alpha is sensible full structure established in the wiki and at least a start at TIGER Review of rail data in that state. Beta is declared when there are no major errors or omissions in a wiki which comprehensively documents a state's rail infrastructure in OSM. When a state's OSM rail data are checked multiple times by at least two OSM and/or wiki editors as being complete and correct rail data for that state, phase goes from "beta" to "final." Now, "complete and correct" includes freight/industrial infrastructure (railway=rail as route=railway relations) and passenger rail (route=train relations), not necessarily signals, milestones, switches, maxspeeds and other similar "minor" infrastructure/data. OSM is in an earlier phase of mapping minor infrastructure, progress continues. State rail wiki documenting minor infrastructure is virtually non-existent presently. It is much more important to map minor infrastructure than to document them, though both (entry and wiki documenting) are welcome. All  Western states have at least an early wiki, some Eastern states do, too. Nebraska/Railroads is a good next candidate for new state /Railroad wikis as wiki progress chugs eastwards, more so all redlinked wiki below. Map your best, wiki your best!

Railroad-organized projects

Here are intended to be more-specific projects listed under each railroad or railroad owner. Listings for Open Historical Map are also intended to be included.

In the USA, the Surface Transportation Board (STB) classifies railroads based on their annual operating revenues. To fall under these railroad classes they must have USA trackage. This is why Canadian National and Canadian Pacific Kansas City are Class I and Ferromex is not. The class to which a carrier belongs is determined in accordance with revenue thresholds:

  • Class I - $504,803,294 or more. All are STB regulated.
  • Class II - Less than $504,803,294, but in excess of $40,384,263. These are sometimes / also known as "regional railroads."
  • Class III - $40,384,263 or less. These are sometimes / also known as "short line railroads."

The revenue thresholds are periodically updated to account for the impact of inflation. These revenue numbers were last updated in 2019.

Class I railroads

Class I railroads are the major owners / operators of rail in the USA, many markets in Canada and some markets in México (because of continental-scope rail company mergers that have taken place):

Class II regional railroads

  • Alabama and Gulf Coast Railrway (AGR)
  • Alaska Railroad (ARR)
  • Buffalo and Pittsburgh Railroad (BPRR)
  • Central Oregon and Pacific Railroad (CORP)
  • Evansville Western Railway (EVWR)
  • Florida East Coast Railway (FEC)
  • Great Lakes Central Railroad (GLC)
  • Indiana Rail Road (INRD)
  • Iowa Interstate Railroad (IAIS)
  • Kansas & Oklahoma Railroad (KORR)
  • Long Island Rail Road (LI)
  • Missouri and Northern Arkansas Railroad (MNA)
  • Montana Rail Link (MRL); reintegration into BNSF pending STB review
  • New York, Susquehanna and Western Railway (NYSW)
  • Paducah and Louisville Railway (PAL)
  • Portland and Western Railroad (PNWR)
  • Providence and Worcester Railroad (PW)
  • Rapid City, Pierre and Eastern Railroad (RCPE)
  • Reading Blue Mountain and Northern Railroad (RBMN), often known as "Reading and Northern"
  • Wisconsin and Southern Railroad (WSOR)
  • Wheeling and Lake Erie Railway (WE)

Class III short line, switching and terminal railroads

Railroads here are better found in the individual state or commonwealth wikis found at United States/Railroads#State (or commonwealth) projects.

Holding companies

This is a listing of parent company as railroad owners. It is incomplete, not containing all USA rail holding companies.

  • Genesee and Wyoming (a dominant player in many markets, for example, almost 80% of the Class III rail in California is G&W line, held in six statewide railroads out of the dozens that G&W owns or "holds")
  • RJ Corman
  • Progressive Rail (based in Lakeville, Minnesota)
  • Omnitrax
  • Railmark Holdings
  • Anacostia
  • Watco
