United Streetcar, LLC, is a manufacturer of streetcars, located in the Clackamas area in the southeastern suburbs of Portland, Oregon, United States. It is the only U.S. company building modern streetcars, as distinct from light rail cars or new replicas of historic streetcars. United Streetcar is a limited liability company and is a wholly owned subsidiary of Oregon Iron Works, Inc. (OIW), which has been in business since 1944. It was originally reported to have been established in early 2007, after OIW was the successful bidder for a contract to construct a prototype streetcar for the city of Portland, but in 2010 the company clarified that it had been formed in December 2005. The company completed its first streetcar in 2009 and has received orders for additional cars.
Oregon Iron Works, a specialized manufacturer of complex structural components and systems, began considering entering the field of streetcar manufacturing in 2004, after realizing that the Portland Streetcar system had purchased vehicles built only by foreign manufacturers, possibly due to the absence of any U.S.-based manufacturers of modern streetcars.
In 2005, Congress approved a federal transportation spending bill which included a US$4 million grant to TriMet for the acquisition, on behalf of the city of Portland, of a prototype domestically manufactured streetcar. With a goal of fostering the domestic production of modern streetcars, the grant had been added into the $286 billion spending bill by Oregon Congressman Peter DeFazio, but did not specify a particular company to be the recipient.
In August 2006, the city of Portland issued a Request for Proposals for the provision of a prototype low-floor streetcar compatible with Portland Streetcar's existing fleet. In anticipation of this, OIW signed a "technology transfer agreement" in February 2006 with Škoda, the Czech company which had built Portland's first seven streetcars, in order to permit OIW to manufacture a streetcar to the existing Škoda 10T design but with mostly U.S. components and assembly. Only two formal proposals were received by the city, and after that of the other bidder was "deemed not to have met the minimum requirement", the contract was awarded to Oregon Iron Works, in January 2007. OIW then announced that it had created a new subsidiary, United Streetcar, LLC, to handle streetcar manufacturing. The value of the contract was $3.2 million, with the balance of the special $4 million federal grant being used to fund the city's costs to administer the grant and oversee the project.
Prototype vehicle completion 
Construction of the prototype streetcar was undertaken at OIW's Clackamas facility (one of two OIW manufacturing facilities). The car was completed in June 2009 and was introduced to the public and the media at a ceremony held in Portland's South Waterfront district on July 1, 2009.
Numbered 015 in the Portland Streetcar fleet, it is the first modern streetcar built in the United States since 1952, since the last PCC streetcar for the San Francisco Municipal Railway. It uses the Škoda 10T design, under license from the Czech manufacturer, and is model variant 10T3. The propulsion equipment—the motors and electronic control system—were fabricated by Škoda, but installation took place at OIW’s/United Streetcar’s plant in the United States, and most other components were fabricated by United Streetcar or supplied by other U.S. companies. Overall, the prototype streetcar has about 70 percent U.S. content, enough to make the car's procurement compliant with federal "Buy America" provisions ( ).
As with the earlier, Czech-built versions of the Škoda 10T, the United Streetcar 10T3 is a four-axle, bi-directional, low-floor streetcar with three doors on each side and wheelchair ramps extending (on demand) from one door per side. It is 66 feet (20.13 m) long and 8 feet (2.46 m) wide and has a maximum speed of 44 mph (70 km/h). In 2010, the company dropped the 10T3 designation in favor of a new model designation, "100", in connection with a decision to use different propulsion equipment in future orders, as described below.
Change in propulsion system 
In 2010, the city of Portland decided to amend its contract with United Streetcar/Oregon Iron Works, to replace the prototype car's Škoda-made propulsion-control system with a new system to be designed by Rockwell Automation, a U.S. company based in Milwaukee, Wisconsin. The propulsion system is the high-tech electronic equipment which controls and coordinates the operation of the car's motors and other key operating components. Car 015's propulsion-control system was made by Škoda, whereas all 10 earlier Portland streetcars—even the seven cars built by Škoda—had control systems supplied by ELIN EBG Traction, an Austrian company (and only installed by Škoda). During acceptance testing of car 015 in late summer and autumn 2009, certain (unspecified) problems were encountered, and Škoda and Portland Streetcar were unable to reach agreement on resolving them. This issue, together with a desire by PS, United Streetcar and others to increase further the U.S. content of streetcars built by United Streetcar, led to discussions between Rockwell Automation and the various interested parties in Portland on the possibility and feasibility of Rockwell designing a control system for the United Streetcar design. In April 2010, the Federal Transit Administration (FTA) approved a $2.4-million grant, to be matched by $600,000 in local money, to fund the replacement of car 015's control equipment with new equipment to be designed by Rockwell Automation. The intention is that, if the partnership with Rockwell proves successful, eventually all streetcars built by United Streetcar would use the U.S.-made Rockwell propulsion system. It was stated that the change would increase the overall U.S. content of the car from around 70% to around 90%, and this was the main factor in gaining federal officials' approval of the $2.4 million in "research funds" needed to allow project to proceed.
Prototype streetcar 015 was transported back to the OIW/United Streetcar factory in May 2010, to await design and then installation of the Rockwell system. With the installation completed in late 2011, it returned to the Portland Streetcar carhouse on April 30, 2012, to begin acceptance testing. It entered service on September 22, 2012.
Current orders 
In spring 2009, the city of Portland announced that it had chosen United Streetcar for an order of six streetcars for a planned expansion of the Portland Streetcar system to the city's east side, and a $20 million contract for this order was signed in August 2009. In light of Portland's subsequent dissatisfaction with the Škoda propulsion system, the city decided in 2010 to modify the OIW/United Streetcar contract for these six cars, to substitute equipment from Elin EBG Traction for the originally planned Škoda equipment, which has delayed their completion. The cars would receive motors supplied by Siemens, which has a U.S. factory, instead of by Škoda. In mid-2011, the order was reduced from six cars to five. These will be United Streetcar model "100", and their delivery is projected for December 2012.
The City of Tucson signed a $26 million contract with United Streetcar on June 7, 2010, ordering seven streetcars for the Sun Link modern streetcar line scheduled to open in late 2013. An eighth car was added to the order in 2012. The original announcement was made in May 2009, but the Tucson project was still awaiting FTA approval at that time. FTA approved the plans in late September 2009 and (jointly with the US DOT) granted $69 million in early 2010 to help complete the project. The Tucson cars will be model variant 200, the main difference from model 100 being a more powerful air-conditioning system.
In April 2012, the District of Columbia Department of Transportation, in Washington, D.C., placed an order for two model 100 streetcars for use on the DC Streetcar's H Street/Benning Road line, under construction for opening in mid-2013, and the order was expanded to three cars in August 2012.
