The 20 axle wagons have two different compositions:

a).- wagon with intermediate beam.
b).- wagon for self-supported load.

The load limit with intermediate beam in 250 tons.

The load limit for self-supported loads in 300 tons.

In both cases it will be necessary to use shifts of 500 mm on each side and elevations of 500 mm if the load exceeds the normal gauge established by Renfe.
