Mini-high platform

Metro and light rail

Most light rail systems have platforms around 12–14 inches (300–360 mm) ATR, allowing level boarding on low-floor light rail vehicles. Most new systems are built to this standard, and some older systems like VTA light rail have been converted. Several systems including MetroLink use higher platforms with level boarding. Several older light rail systems have high-floor vehicles but low platforms, with mini-high platforms or lifts for accessibility. Some, like the MBTA Green Line, are being converted to low-floor rolling stock, while others, like Baltimore Light Rail have permanent mini-high platforms. Muni Metro has 34-inch (864 mm) high platforms in the subway section as well as some surface stops, and mini-high platforms at other surface stops; the vehicles have movable stairs inside to serve both high and low platforms.
