Improved steel railway crossing
A steel railway crossing 10 having a body 20 with a top running surface 30 and a bottom support surface 40; said body having a first hardness and a first ultimate tensile strength (UTS); said top running surface having been exposed to an Explosive Device Hardening (EDH) cycle to achieve a second hardness greater than said first hardness; said bottom support surface having been exposed to an EDH cycle to achieve a second UTS greater than the first UTS. Additionally disclosed is a method of manufacturing a railway crossing comprising the steps of: casting at least a section of said rail crossing 10 from steel, said at least one section having a top running surface 30 and a bottom support surface 40; exposing at least a portion of the top running surface to a first EDH cycle to increase wear and deformation resistance of the running surface 30; and exposing at least a portion of the bottom support surface 40 to a second EDH cycle to increase UTS strength of said section.
