Vehicles  Select the image to see a larger version. Modern streetcars are designed to fit the scale and traffic patterns of the neighborhoods through which they travel. The same type of streetcar vehicles that will be used in Washington, DC, are currently in use in Portland, Oregon. They are manufactured by Skoda-Inekon in Plzen of the Czech Republic. These cars are 2.46 meters (about 8 feet) wide and 20 meters long (about 66 feet), about 10 inches narrower and 1/3 the length of a light rail double car train. They are able to operate mixed traffic and easily accommodate to existing curbside parking and loading. A unique shallow 12-inch deep track slab design reduces the construction time and utility relocations. Maneuverability of the shorter and narrower Skoda vehicles has allowed the 8-foot wide track slab to be fitted to existing grades, limiting the scope of street and sidewalk reconstruction.
