Maintenance Facility Design

Primary Guidance

  • Applicable to both Rail and Bus Maintenance Facilities and Buildings.
  • Designed to:
  • Optimize the functional requirements identified for 20-year horizon needs.
  • Support best practices for sustainability minimizing operations costs and energy consumption and providing long-term cost benefits.
  • Buildings should be located on site to optimize yard operations and site access.


  • A Maintenance Facility is an essential part of a transit system, which comes at a significant capital cost, and its design influences the daily system operating costs. Design should consider the following factors:
  • Building location on a selected site.
  • Facility design that is integrated with yard operations for a rail system or site layout for a bus facility.
  • Functionality
  • Operations:
  • Pre-Inspections;
  • Process Flow – train and bus movement
  • Maintenance – heavy, daily, cleaning, and inspections.
  • Yard Functionality:
  • Track and bus lane layout
  • Site constraints – drainage and storm water management, circulation patterns, program requirements, environmental requirements
  • Facility program:
  • Provide adequate facilities for personnel and administration including parking.

Site Considerations

  • A Maintenance Facility Building should be located on a relatively flat site with sufficient utility service such as power, communications. water, and sewer available and a suitable outfall for storm drains and storm water management to minimize capital costs. The site should be integrated with operations planning to optimize future (20- year horizon) operations by minimizing dead-head runs and other operational efficiencies. The site should have sufficient highway/roadway access to allow for efficient delivery of vehicles. Highway/roadway access should not be susceptible to flooding.
