A track configuration that allows rolling stock of different widths to operate over the same right-of-way. It typically features three rails, where one rail is shared and two others are spaced at different distances to match the respective gauges. This setup eliminates the need to transfer cargo or passengers between separate trains where distinct railway networks meet.
We've a mile of mixed gauge running up to the transfer shed so the narrow gauge cars can spot right next to the standard hoppers.
