Tren Urbano is a 17.2-km heavy rail two-track transit line serving the San Juan metropolitan area, including multiple universities and technical colleges, major medical centers, the city’s financial district, entertainment venues and many residential neighborhoods. The system includes a 15,000 square meter administration and maintenance facility. Train service operates from 5:30 a.m. to 11:30 p.m. with 8-minute peak period headways.

Project Details

ACI was the Operations partner in the Siemens Transit Team (STT) for the Design-Build-Operate-Maintain (DBOM) Tren Urbano project, first in the nation. As such, ACI played an active and important role during the design, construction and commissioning of the project in order to ensure long-term operational efficiency and maintainability of the system. Important changes influenced by ACI included more standardized specifications, re-design of canopy roofs, relocation of certain equipment on vehicles and elimination of some “specialized hardware” in favor of commercially available materials.

Since passenger rail service had long been absent in Puerto Rico when Tren Urbano was being planned, ACI was faced with the challenge of building a workforce from the ground up. ACI undertook a major outreach and recruiting effort by partnering with the University of Puerto Rico and other higher education centers, providing paid internships and implementing a mentoring program. Throughout the term of the contract, Puerto Ricans have comprised nearly 100 percent of the Tren Urbano workforce. Since 2016, the service has been operated by a joint venture between ACI and Herzog Transportation Services Inc.

Noteworthy Accomplishments:

  • Consistent on-time performance and completed trips over 99%, making Tren Urbano among the best performing heavy rail system among all U.S. transit systems.
  • Zero fatalities and one FTA reportable injury (trespasser).
  • Significant cost savings to the Authority as a result of ACI-led actions to both cut operating costs (including reduced power consumption) and to facilitate increased revenues.
  • Major assistance to PRHTA to extend life expectancy of obsolete systems and obtain funding for upgrade/replacement.
  • Consistent customer ratings of service as good or excellent.
  • Rapid recovery and restoration of service following the devastating effects of Hurricane Maria in 2017.

Valley Metro light rail is a 26-mile line that serves major destinations such as Chase Field, Talking Stick Arena, Arizona State University stadiums, and downtown Phoenix as well as Tempe and Mesa. Weekday trains run every 12 minutes from 7:30 a.m. to 6:30 p.m. and every 20 minutes all other hours. Weekend service trains run every 15 to 20 minutes. Light rail service is coordinated with bus service to provide a seamless network for customers.

ACI commenced revenue service on the initial 20-mile Light Rail Transportation Services on December 27, 2008.  In the summer of 2015 ACI mobilized for the Central Mesa extension and in the winter of 2016 ACI mobilized for the Northwest extension. During the mobilization for these extensions, ACI provided personnel for testing and commissioning, hired and trained additional operators and supervisors; retrained our operators and supervisors; and completed System Safety Certification.

Project Details

ACI is responsible for:

  • Hiring and training all staff
  • Implementing drug and alcohol testing in strict accordance with 49 CFR Part 40 (with the use of a subcontractor)
  • Dispatch and operation of trains
  • Managing and staffing 24/7 operations control center
  • Managing the operation’s safety program
  • Assisting customers with routing, ticketing and boarding information
  • Customer service inquiries

Phoenix Commuters BoardingACI manages train operators, transportation supervisors, operations safety office, and the operations control center. Our operations staff is trained in proper customer service techniques. During the start-up period, ACI successfully negotiated a Memorandum of Understanding with the Amalgamated Transit Union for the screening, hiring, and training of the initial complement of light rail operators and then followed up with a multi-year collective bargaining agreement. ACI has since successfully negotiated two additional collective bargaining agreements with the ATU without any occurrence of strike, walkout or work stoppage. ACI also negotiated two collective bargaining agreements with the Office and Professional Employees International Union (OPEIU) Local 30 covering three job classifications. ACI trained these former bus operators on light rail vehicle operations and the challenges of operating an in-street light rail service that traverses 173 intersections. Our training programs emphasize safety and defensive driving practices as well as a high level of awareness for pedestrians, cyclists and vehicle drivers. Through repeat training, safety awareness reminders and communication with the OCC, ACI’s staff safely and successfully operates the Valley Metro system.

Noteworthy Accomplishments:

  • For the past ten years of operation, average annual on time performance for transportation has been 99.6% on time.
  • Addressed all passenger inquiries and issues that arose on the system; the client reports less than one valid complaint per 100,000 boardings.
  • Achieved excellent customer satisfaction ratings, including 91.6 percent of riders rating “trains running on time” as a 4 or 5 based on a 1 to 5 scale (2013).

In 2010, RTD awarded Denver Transit Partners (DTP) a 34-year contract to design, build, finance, operate and maintain the commuter rail lines of the RTD's Eagle P3 Project. Denver Transit Operators (DTO), the O&M contractor for the Eagle Project, was formed by a joint venture with ACI, the largest privately-held provider of contracted passenger rail services in the United States, Balfour Beatty Rail and Fluor.

The Denver commuter rail system includes 3 commuter rail lines and a maintenance facility. The A-Line opened April 22, 2016, followed by the B-Line in July 2016, and an anticipated opening of the G-Line in 2018. The A-Line provides service between Denver Union Station (DUS) and Denver International Airport. The B-Line serves the area between DUS and Westminster. The G-Line will bring service from DUS through northwest Denver, Adams County and Arvada, to the end-of-line in Wheat Ridge.

Project Details

A and B Lines have Positive Train Control (PTC), a new technology mandated by Congress. By the end of 2018, all railroads are required to have installed PTC. It provides an extra layer of safety, preventing speeding and other unsafe train movements and protecting railroad workers who are on or around the tracks. The Denver commuter rail system also features a wireless grade-crossing warning system tied to the PTC system.

From opening through December 2017, the A and B Lines have transported 11.4 million passengers over 65 miles of track. The system carried an average of 19,550 weekday passengers in 2017 and has completed more than 110,000 trips since inception. During the 4th quarter of 2017, system-wide on-time performance was 97.7% and the percentage of A-line trips that arrived at Denver Airport Station within 5 minutes of expected arrival time was 98%.

As exclusive operator of the Eagle P3 lines, DTO interacts with Amtrak, Burlington Northern Santa Fe (BNSF), and Union Pacific (UP) on a daily basis.

The Purple Line is a planned light rail line that will be developed and operated by a public private partnership, Purple Line Transit Partners, the concessionaire selected by the State of Maryland for the 36-year P3 contract. When completed, Purple Line will serve six major activity centers, including Bethesda, Chevy Chase, Silver Spring, Takoma-Langley Park, College Park/University of Maryland and New Carrollton in an alignment that is just inside the Washington DC I-495/Capital Beltway. It will intersect with rapid transit, commuter rail and intercity services operated by WMATA, MARC and Amtrak.

The Purple Line transitway will be largely at grade with one short tunnel section, three elevated sections and several bridge structures. The service will operate mainly in dedicated or exclusive lanes with some mixed traffic operations in the area of the University of Maryland campus. Light rail vehicles will be ADA compliant, 80% low floor vehicles, providing ease of boarding for passengers, good visibility and ergonomics for the operator, clean and comfortable passenger accommodations, and safe, reliable operation.

The project also includes design and construction of the Capital Crescent Trail between Bethesda and Silver Spring and reconstruction of the existing Montgomery County Green Trail.

ACI is a partner, along with Fluor and CAF USA, in Purple Line Transit Operators, the entity that will operate and maintain the system over the life of the contract. During the construction and pre-revenue phases, PLTO is providing design reviews focused on maintainability and operability, developing operational plans and procedures, staffing the system, and developing and providing training for operations, vehicle and system maintenance.
