Saudi Arabia Railways Orders 10 Additional Stadler Trains for CHF 300 Million to Upgrade Riyadh-Dammam Corridor

Saudi Arabia Railways (SAR) has finalized a CHF 300 million agreement with Swiss train manufacturer Stadler Rail to acquire ten additional next-generation intercity passenger trainsets, doubling its procurement to 20 modern trainsets for the key Riyadh–Dammam rail corridor. Exercising a contractual expansion option from its initial February 2024 order, the national railway operator aims to significantly boost intercity seating capacity, passenger frequencies, and travel comfort across Saudi Arabia’s central and eastern provinces ahead of targeted commercial operations in the second half of 2029.

The expanded rolling stock agreement includes comprehensive long-term maintenance support, reinforcing Saudi Arabia’s Vision 2030 objective to transition domestic and international visitor mobility toward sustainable, high-capacity public rail infrastructure linking the capital with the Arabian Gulf coastline.

Fleet Procurement and Corridor Milestone Overview

The Riyadh–Dammam railway represents one of the kingdom’s most established passenger rail arteries, serving vital intermediate population centers including Hofuf (Al-Ahsa oasis) and Abqaiq before reaching the coastal commercial hub of Dammam.

Contract & Operational Dimension	Confirmed Specification
National Railway Operator	Saudi Arabia Railways (SAR)
Rolling Stock Manufacturer	Stadler Rail
Contract Value (Option Exercised)	CHF 300 million (~SAR 1.3 billion)
Total Stadler Fleet Ordered	20 intercity passenger trainsets (10 in Feb 2024 + 10 in Oct 2026)
Primary Rail Corridor	Riyadh – Hofuf – Abqaiq – Dammam (East Train Network)
Testing & Demonstration Debut	2028
Target Commercial Passenger Launch	Second half of 2029 (H2 2029)

The procurement contract doubles the number of high-capacity trainsets assigned to the eastern rail route, ensuring robust fleet resilience across seasonal peaks such as Eid holidays and winter tourism festivals.

Desert Engineering and Modern Passenger Comfort

Operating across the Arabian desert requires specialized engineering solutions to withstand extreme ambient temperatures exceeding 50°C and pervasive fine sand drifts. Stadler is developing these bespoke trainsets with rugged technical systems tailored to Gulf climates:

• Advanced Aerodynamic Sand Filtration: Multi-stage centrifugal air intakes and specialized filtration prevent desert dust from infiltrating traction motors and sensitive electronics.
• Redundant HVAC Climate Systems: Dual-compressor climate control architecture ensures passenger coaches maintain stable, chilled interior temperatures even during peak summer heatwaves.
• Multitier Travel Classes: Configured with luxury first-class suites, business-class lounges, and comfortable family-friendly standard seating equipped with universal charging docks and high-speed Wi-Fi.
• Ample Luggage Accommodations: Generous overhead and end-car baggage zones specifically dimensioned to support long-haul international air-rail transfer travelers and family groups.

Expanding Passenger Demand and Vision 2030 Tourism Synergy

The rail investment directly mirrors surging travel numbers across Saudi Arabia. Official statistical data from the Ministry of Tourism highlights rapid growth across both domestic and overseas leisure segments:

Tourism Performance Metric	Reported 2025 Volume	Economic / Market Impact
Total Annual Visitors	123.0 million travelers	6.0% overall growth compared to 2024
Inbound International Travelers	29.3 million visits	SAR 176.6 billion inbound expenditure
Domestic Leisure & Business Trips	93.3 million visits	SAR 127.1 billion domestic spending (+8.3%)
Combined Tourism Expenditure	SAR 303.7 billion	Direct tourism contribution reaches 4.9% of GDP
Sector Employment	1.03 million tourism jobs	Supported by Tourism Development Fund investments

Enhanced rail frequencies will allow international travelers holding Saudi eVisa permits to explore beyond Riyadh's urban centers, taking rail day-trips to the UNESCO World Heritage-listed date palm groves of Al-Ahsa Oasis in Hofuf or onward to maritime resorts in the Eastern Province.

Practical Guidance for Current Rail Travelers

While the new Stadler trains are scheduled to begin commercial passenger operations in late 2029, current travelers along the Riyadh–Dammam line should take note of present operational parameters:

1. Current Service Schedules: Daily passenger journeys continue operating under SAR's existing East Train timetable using current diesel locomotive sets; reservations should be secured via the official SAR portal or mobile app.
2. Luggage and Station Check-In: Standard baggage allowances mandate check-in screening at Riyadh and Dammam stations at least 30 minutes prior to departure.
3. Tourist eVisa Entry: International tourists can utilize Saudi Arabia’s one-year, multiple-entry eVisa (which permits stays up to 90 days) to travel freely across the national rail network.
