SAR and CAF partnership for train modernization

Following a two-year programme of design, testing, certification and training, the first train fitted with CAF’s latest ERTMS technology has entered passenger service on SAR’s (Saudi Arabia Railways) Riyadh to Dammam network.

The fitment of the CAF's Auriga ETCS OBU is a key first step in SAR’s modernization of the Riyadh to Dammam railway, allowing the introduction of advanced signalling to ERTMS Level 2, increasing safety and efficiency. This retrofit programme involves a multi-million Riyal investment by SAR and will future proof the trains, reduce delays and improve performance. The work is being carried out in SAR’s strategic train overhaul facility in Riyadh by CAF, SAR's key delivery partner. The whole fleet will be enabled to operate under ERTMS Level 2 in first quarter 2026.
