Loading gauge

A loading gauge to check the maximum height of loaded rail vehicles

A Loading gauge defines the maximum height and width for railway vehicles and their loads to ensure safe passage through bridges, tunnels and other structures.^[1] Classification systems vary between different countries and gauges may vary across a network, even if the track gauge remains constant.
