TRC has the largest private practice bus engineering staff in North America. The firm regularly provides engineering services for new bus designs, bus manufacturing, bus renovation and retrofit, alternative fuels, and fleet performance. TRC develops bus specifications for clients in preparation for the purchase of new bus fleets.

What we provide:

  • Engineering advise during negotiations with bus manufacturers

  • Engineering analyses on fleet defects and warranty claims

  • Engineering analyses on structural failures on buses

  • Investigates issues related to bus accidents and bus fires

  • Expert witness testimony in cases involving bus performance, design and maintenance

TRC also provides services to clients in the field of alternative bus fuels and related storage technology.  TRC has provided technical seminars to transit systems on the introduction of low sulfur diesel fuels in bus fleets, and we have evaluated alternative fuels options for transit systems looking to move away from diesel fuels.

TRC has assembled the finest team of bus engineering experts that can be found anywhere in the U.S. transit industry. TRC‘s privately owned Bus Technology Center is the largest in North America. Our bus technology center provides technical support in bus design and engineering, bus manufacturing and bus maintenance. 




TRC often runs turn-key bus procurements for clients where we act as the client’s agent in conducting pre-bid conferences, responding to vendor’s requests for approved equals, evaluating bids, and conducting contract negotiations with the selected bus builder. 


Once buses enter production, TRC provides ongoing technical support services to our clients through assignment of resident quality assurance inspectors in the factories who watch over every step of the bus assembly process. Senior TRC engineers provide technical guidance to the resident inspectors and help clients arbitrate problems that arise during production. TRC also has conducted scores of Buy America audits to ensure manufacturers’ compliance with FTA regulations on domestic contents and final assembly. TRC has conducted such inspections on more than 15,000 new buses since the company’s start in 1990. 





Bus re-manufacturing projects are often more complex than assembling new buses. TRC provides expert help to transit agencies in all phases of bus re-manufacturing including fleet evaluation, specification development, procurement management, and on-site inspection services during production. TRC has many years of hands-on experience in renewing the useful life of transit buses.




TRC provides technical support and technician training in bus electrical systems. TRC assists in diagnosis of electrical problems on buses, and we provide training of your bus technician on-site at your shop.






TRC runs general bus procurements for all transit needs. We have a large and experienced staff with the skills necessary to take on a wide spread of requests. Please contact us for your unique bus procurement with any questions.
