The SLRV is a double-ended high-floor articulated light rail vehicle 71 ft (22 m) long overall (over the anticlimbers), in the same range as many heavy rail vehicles both at the time and now, but noticeably shorter than many other modern LRVs such as the at-minimum-81-foot (25 m) Siemens S70 and S700 commonly found today, which rides on three ...
