Asset library: types, dimensions, standards

The common ISO container types and their special designs, plus the swap bodies, wagons and legal limits they travel with on land.

Every value comes from a named data sheet, standard or statute and can be checked there. Where manufacturers or keepers publish different figures for the same type, we show both. Photos show real units of the type, not necessarily the exact data-sheet unit. As of: 2026-10-23.
