The Adams axle is a form of radial axle for rail locomotives that enable them to negotiate curves more easily. It was invented by William Bridges Adams and patented in 1865. [ 1 ] The invention uses axle boxes that slide on an arc in shaped horn blocks , so allowing the axle to slide out to either side.
An axlebox, also known as a journal box in North America, is the mechanical subassembly on each end of the axles under a railway wagon, coach or locomotive; it contains bearings and thus transfers the wagon, coach or locomotive weight to the wheels and rails; the bearing design is typically oil-bathed plain bearings on older rolling stock, or roller bearings on newer rolling stock.

The idea was tried successfully by William Adams on the London and South Western Railway (LSWR) in 1882 with his 415 class. Radial axles were also used in locomotives designed by F.W. Webb of the London and North Western Railway, and by William Stroudley and R. J. Billinton of the London, Brighton and South Coast Railway (LB&SCR).
The overland train concept first developed as a way to haul trees out of the bush, without the need to prepare a road capable of supporting a traditional truck. A truck would need to have a surface flat and strong enough for its driven wheels, normally four at the rear of the cab, to gain traction needed to climb any grades.
