About This Report
This industry report for NAICS 485111 draws on transit ridership and operating data from the U.S. Census Bureau[4], employment statistics from the Bureau of Labor Statistics[5], and small business benchmarks from the Small Business Administration[6]. Fair Market Value compiles this NAICS 485111 profile to support valuation professionals analyzing transit operating contracts, private transit service providers, and transit-adjacent businesses. Our research team updates this content quarterly to reflect funding changes and service data.
Industry Definition & Overview
Mixed Mode Transit Systems (NAICS 485111) encompasses public and private transit agencies that operate passenger transportation using at least two different modes, such as commuter rail combined with bus service, light rail paired with trolleybus networks, or subway systems integrated with surface bus routes. The U.S. Census Bureau[4] classifies these operations together because a single entity manages and coordinates multiple transit technologies to serve a contiguous service area.
These systems represent some of the largest and most complex transit operations in the country. Major metropolitan areas including New York, Chicago, Boston, and San Francisco operate mixed mode networks that carry millions of passengers daily. Revenue streams combine farebox collections, dedicated sales tax allocations, federal formula grants from the Federal Transit Administration, and state transportation funding. Capital investment requirements are substantial, with rail infrastructure, bus fleet replacement, and fare collection technology driving multi-billion-dollar budgets for the largest agencies.
Workforce composition spans vehicle operators, maintenance technicians, dispatchers, station attendants, and administrative staff. Labor costs typically account for 60 to 70 percent of operating budgets. Many agencies operate under collective bargaining agreements that influence scheduling, overtime rules, and benefit structures. Service planning balances ridership demand against available funding, with agencies continuously adjusting routes and frequencies to match changing commuter patterns across their multi-modal networks.

Frequently Asked Questions
Common questions about this industry.
What types of businesses fall under NAICS 485111?
This code covers transit agencies and private operators running passenger service across at least two transportation modes within a single system. Examples include a city transit authority operating both subway trains and bus routes, a regional agency combining commuter rail with local bus feeder service, or a private contractor managing both light rail and bus rapid transit corridors. The U.S. Census Bureau[4] requires the multi-modal element for classification here.
How is NAICS 485111 structured differently from single-mode transit codes?
Single-mode codes like 485112 for commuter rail and 485113 for bus systems each cover agencies operating just one type of vehicle technology. NAICS 485111 applies when a single operating entity manages two or more modes together, such as rail plus bus. The organizational integration of scheduling, fare collection, and service planning across modes is what distinguishes mixed mode systems from separate single-mode operators sharing a service area.
What is the SBA size standard for NAICS 485111?
The Small Business Administration sets the size standard at $29 million in average annual receipts over five years. Most large urban transit agencies far exceed this threshold, but smaller suburban transit operators and private companies holding transit operating contracts may qualify. Details are available in the SBA size standards table[9].
What NAICS codes are closely related to mixed mode transit?
Closely related codes include 485112 for commuter rail systems, 485113 for bus transit operations, 485119 for other urban transit, and 485210 for interurban bus service. The distinction centers on whether the operator runs multiple transportation modes under unified management. Single-mode operators fall into their respective codes even if they coordinate transfers with other agencies.
What industries are connected to mixed mode transit operations?
Connected industries include commuter rail systems that share track and infrastructure, bus manufacturers and maintenance providers, highway and bridge construction firms that build transit corridors, and consulting firms specializing in transit planning and fare integration. Real estate developers near transit stations and advertising companies managing transit media also interact closely with mixed mode agencies.
What activities are included in NAICS 485111?
Included activities cover operating fixed-route bus service alongside rail transit, managing integrated fare systems across modes, coordinating transfer connections between bus and rail schedules, operating paratransit demand-response service as a complement to fixed routes, and maintaining vehicle fleets across multiple technology types. According to the U.S. Census Bureau[4], the defining feature is unified multi-modal operation under a single entity.
Can mixed mode transit operators access SBA loans?
Private transit operators and contractors under the $29 million revenue threshold can access SBA financing programs. The 7(a) program[7] supports vehicle fleet purchases and technology investments for fare collection systems. Market 504 program[8] finances maintenance facility construction and real estate acquisition. Public agencies are generally ineligible for SBA loans but their private contractors and subcontractors may qualify.
Where are mixed mode transit systems concentrated in the United States?
Mixed mode systems concentrate in major metropolitan areas with sufficient population density and funding to support multiple transit technologies. New York, Chicago, Boston, San Francisco, Washington D.C., and Philadelphia operate the most extensive multi-modal networks. According to the Bureau of Labor Statistics[5], transit employment clusters in these dense urban centers where ridership volumes justify capital investment in both rail and bus infrastructure.
