Seattle Streetcar is a modern ligt rail system which first opened in 2007 when the South Lake Union line started operation. Then nine years later it was joined by a second line with the first services on the First Hill line commenced. The two lines have no connection but both use streetcars built by Inekon Trams - three Inekon Trio-12 vehicles built in the Czech Republic for the South Lake Union line and then seven Inekon Trio-121 at the time of the opening of the First Hill line, one of which was to boost capacity on the South Lake Union line. Three of this second batch were also built in the Czech Republic with the others assembled under contract by Pacifica Marine in Seattle.
