Diesel Light Rail
A few recently opened systems in North America use diesel-powered trains, including the River Line in New Jersey (opened in 2004), the O-Train in Ottawa (opened in 2001), and the SPRINTER in northern San Diego County, California. Diesel operations are chosen in corridors where lower ridership is expected (and thus do not justify the expense of the electric power infrastructure) or which have an "interurban" nature with stations spaced relatively far apart (electric power provides greater acceleration, making it essential for operations with closely spaced stations). Operations with diesel-powered trains can be an interim measure until ridership growth and the availability of funding allow the system to be upgraded to electric power operations.
