Cast iron rails, 4 feet (1.2 m) long, began to be used in the 1790s and by 1820, 15-foot-long (4.6 m) wrought iron rails were in use. The first steel rails were made in 1857 and standard rail lengths increased over time from 30 to 60 feet (9.1–18.3 m). Rails were typically specified by units of weight per linear length and these also increased.
A related design is the SD-400/SD-460 high-floor light rail vehicle, which was initially built by a Siemens–Duewag joint venture. Siemens purchased Duewag in 1999, and assembled the SD-460 model alongside the SD-100/SD-160 in Florin, California.
