ISO containers, also referred to as intermodal containers, are used to transport freight throughout the world. ISO containers are designed for transportation by more than just one mode: such as road and rail, or rail and ship.    They are specifically designed for convenient lifting and movement.   The relevant standard for ISO containers is ISO 668:1995 Series 1 freight containers - Classification, dimensions and ratings

ISO containers are manufactured in standard sizes. The standard width of ISO containers is 8 feet (2.44m ), the standard heights are 8 feet 6 inches (2.59m), and 9 feet 6 inches (2.9m), and the most common lengths are 20 feet (6.1m) and 40 feet (12.19m). The containers are also manufactured in a number of different lengths from 24 feet (7.31m) to 56 feet (17.22m)

Typical recent London Underground Rolling STock is 2.63m Wide x 2.875m Wide x 17.77m Long supported on 4 wheel pairs the wheels being 0.77m dia.

At Roadside = 6.6m Long x 2.7m wide
Within a single bay = 4.8m long x 3.6m Wide

The authorities need to be notified if a road vehicle is over 3m wide and/or if a vehicle is over 18.75m long and/or if the weight distribution of the vehicle exceeds the following

Only Bridges with clearance height of less than 4.95m (16'-3") are indicated on road maps.

BMW 525 4d.... Length = 4.84m width 1.84m height 1.46m Mass 1560kg
Ford Fiesta .... Length = 3.918m width(noMirrors/ mirrors)1,683-1,905 height (unloaded)1.468m Mass 1100kg
Range rover(2009).... Length 4,972m Width(over mirrors) =2.1929m Height 1,903m Mass (Diesal) = 2717kg .

The freight dimensions typically range in width of 2.5m to 2.7m and heights over tracks of 3.3m to 3.7m.    The height of the wagons are generally between 1,4 and 1,8m high



The maximum load on a 4 wheel flatwagon is about 66 tonnes

The British Rail Standard Rail Gauge width is the distance between the inner faces of the rails on which the wagon coach wheel run = 4'-8.5" (1.435m)......This is the same dimension as most of Europe and 60% of the world - including the US .. we did have an influence on the world besides our language..
