HSC Harsco Corporation

Harsco Corporation (NYSE: HSC) announced today that its rail division has signed a nearly $31-million contract with Saudi Railway Company (SAR) to provide it with a 60-stone rail grinder. Additionally, to support the immediate needs of the customer, Harsco Rail will provide two years of grinding services starting in 2022.

In demonstrating its commitment to SAR, a team of operators and mechanics based in Saudi Arabia will operate a 20 stone machine and handle all customer requests. Additionally, Harsco Rail will establish a local warehouse for spares and consumables for all customers in the region.

"Our continued relationship with the Saudi Arabia and Middle Eastern markets is a significant milestone for us," said Claus Heuschmid, Harsco Rail's Chief Operating Officer. "This contract demonstrates Saudi Railway Company's confidence in Harsco Rail as a valued supplier that delivers innovative and sustainable advanced products. We look forward to a long relationship with SAR, and we are very appreciative of the trust they have placed in us."

Harsco Rail's 60 stone grinder, which removes surface defects on rails and re-profiles the railhead on both rails, is one of the most technologically advanced grinders working today.
