SAR placed the order for the wagons in October and they will support industrial mining operations led by Ma'aden at Wa'ad Shamal Industrial City in the Sirhan-Turaif region of northern Saudi Arabia. Greenbrier is building the wagons at its Wagony Swidnica subsidiary in Poland, and in addition to ECP brakes, Wabtec will provide bogies, draft gear, and bogie-mounted brakes.

ECP equipment uses an electronic signal to apply and release the brakes simultaneously throughout the train enabling operation at higher speeds and providing up to a 60% reduction in stopping distance.

The components for the wagons, which will be used to transport molten sulphur and phosphoric acid, will be delivered over the next two years. Delivery by Greenbrier to SAR is set to commence in the second half of 2016 and conclude in 2017 and 2018, depending on the wagon type.
