Visualizing U.S. Transit and Rail Manufacturing
About the Map
This interactive map provides information on U.S. manufacturing facilities involved in the transit supply chain, showing company/facility names, locations, and information about products manufactured and vehicle types. It also includes geographic details, including congressional districts, coal closure communities, disadvantaged communities, and deindustrialized communities (see Underlying Data section for details).
Underlying Data
Scope of Data
BGA’s transit data covers U.S. manufacturing facilities involved in the supply chain for transit bus and passenger rail vehicles, along with transit infrastructure. This includes facilities that produce materials, parts, and components for buses, passenger rail vehicles, and transit infrastructure, as well as those involved in final vehicle assembly. The scope encompasses the supply chains for all types of buses used by transit agencies, including metro and coach buses, shuttles, and paratransit vehicles, as well as school buses. It also covers all passenger rail applications, including commuter, light rail, high speed and intercity rail, metro/subway, trolley/tram, and monorail.
The data set focuses exclusively on manufacturing facilities, including those in small-batch production phases that have not yet scaled to mass production. Facilities solely dedicated to research and development (R&D), such as those testing or developing new products, are excluded. Non-manufacturing facilities—including headquarters, corporate offices, warehousing, parts replacement centers, and similar operations—are excluded. Information on closed facilities is included, while announced/planned facilities not yet in operation are excluded.
Data Collection Process
This dataset represents an update to previously collected transit supply chain data. It incorporates updated information for existing facilities and identifies additional facilities not previously collected. We collect facility location details such as address as well as information relevant to product classification, including vehicle type (transit bus, high-speed rail, etc.), production tier (e.g. Tier 1-4; see Data Dictionary below for details), and product descriptions. While details on what products are manufactured on-site and their classifications are generally clear for assembly facilities, it is less clear for suppliers farther up the supply chain, as components can potentially be used in multiple types of vehicles.
Data Sources
All data was collected from publicly available sources, primarily from company websites, recent news articles, and transit industry resources such as conference lists, publications, and reports. Google Maps was used to verify facility locations.
Disclaimers
We do our best to ensure that the data we release is as complete, accurate, and useful as possible. However, companies and facilities provide varying levels of detail on their websites about which industries they serve, which parts and components they make, and which vehicle types they produce those parts and components for. They also periodically make changes to their production processes and strategies. As such, we cannot always precisely determine which products are made at a given manufacturing facility, or which industries or vehicle types they are produced for.
Materials suppliers——may be included if they potentially serve the transit industry but may not have been confirmed to do so. Similarly, vehicle type information represents either a clear indication (e.g., through current or previous advertising) that a facility supplies for a specific vehicle type, or a facility’s potential ability to supply for a specific vehicle type, even if that potential has not been confirmed.
Data Dictionary
| Map Filter Fields | Description |
| Sector | Indicates the transit sector that the facility supplies. Selecting “Bus” shows facilities with bus-specific production, while selecting “Rail” shows facilities with rail-specific production. Facilities supplying both sectors will appear under both sector filters, with pop-up details corresponding to the selected sector. |
| State | The state where the facility is located. |
| Congressional District
|
The congressional district where the facility is located, following boundaries for the 119th Congress. Using U.S. Census Bureau shapefiles to determine location: For states which redrew districts for the 119th Congress (AL, LA, GA, NC, NY), 2024 TIGER/Line Congressional Districts (119th) shapefiles for the respective states were used. For states where 119th and 118th Congressional Districts stayed the same, the 2023 Cartographic Boundary Files Congressional Districts (118th) national shapefile was used. Note: a national shapefile of the 119th congressional districts from the Census Bureau was not available at the time of publishing.
The congressional district boundaries visualized on the map use a file for the 119th congress published by ESRI. |
| Facility Status | The current status of the facility as of late 2025. This can be “Operating,” “Closed,” or “Expected Closure.” The majority of facilities are “Operating.” Facilities with other statuses were not collected systematically and thus may not be comprehensive. |
| Tier | Where the facility sits in the supply chain.
When a facility manufactures in multiple tiers, it is assigned the lowest numbered/most final tier. For example, a facility that performs final assembly and also manufactures propulsion systems is labeled as Tier 1 on the map but will appear in results both when Tier 1 or Tier 2 filters are selected. |
| Low Emissions Vehicles (bus only)
|
Indicates facilities in the bus supply chain that produce materials, parts, or final assembly for electric vehicle (EV) buses. Non-EV-specific inputs (e.g. tires) are excluded. This excludes fuel agnostic inputs to EV vehicles (e.g. tires). |
| Hard-Hit Communities
|
A list of the hard-hit communities that the facility is located in. These can be “Disadvantaged Communities” as defined by CEQ; “Coal-Closure Energy Communities” as defined by DOE, and “Deindustrialized Communities” as defined by the BlueGreen Alliance (BGA). See BGA’s Hard-Hit Communities Map for more information. |
| Map Popup Fields | Description |
| Company Name | The name of the company. This is displayed in the popup header when a facility point is selected on the map. In cases where the facility is known by a colloquial name (e.g. MW Industries: Sussex Wire), it is included as part of the name. |
| Location | The city and state where the facility is located. This is displayed in the first line of text in the popup when a facility point is selected on the map. |
| Public Description | A brief description of the facility’s activities. This is displayed in the second line of text in the popup when a facility point is selected on the map. |
| Vehicle Type | A list of the vehicle types made or supplied by the facility. For the bus sector, these are: “Coach,” “Metro Bus,” “Paratransit,” “School,” “Shuttle.” For the rail sector, these are: “Commuter,” “High Speed,” ““Light Rail,” “Monorail,” and “Trolley/Tram.”
This is displayed in the last line of text in the popup when a facility point is selected on the map. This field may be left blank when there is significant uncertainty about past, present, or potential vehicle types associated with the facility. |
