With six driverless lines and a total route length of 175km, Riyadh is planning the world's largest subway project and for the first time we get to see its new trains. A rapidly expanding city, the population has doubled to more than six million people since 1990. This investment in the Saudi Arabian capital’s public transport infrastructure is meant to alleviate the local traffic problems which this growth has helped created and is now stalling further development. And today we are getting a first look at some of the Inspiro metro trains from Siemens that will be rolled out on the network considered the world’s largest metro project. Siemens is to supply the entire turnkey system for Lines 1 and 2 of the six, and their €1.5 billion order includes the metro trains themselves plus an electrification system, and signalling and communication equipment.
Siemens was awarded the order in 2013 by the High Commission for Urban Development (ArRiyadh Development Authority) and is also responsible for integration of the railway systems on these two lines, which cover a total of 64 route kilometers.
“Our project teams in Vienna and Saudi Arabia poured all their heart and soul into the development and completion of the first train which is specially equipped for the extreme climatic conditions in Riyadh. So we are especially proud to be the first of the three consortia to present our vehicle to the public,” says Jochen Eickholt, CEO of Siemens Mobility. The first train is currently being tested for extreme conditions in the climatic wind tunnel at Rail Tec Arsenal (RTA) in Vienna. In spring 2016, dynamic testing will commence at the Siemens Test and Validation Center in Wildenrath, Germany.
Siemens is to supply 74 Inspiro type metro trains. These trains with their all aluminium car bodies are designed to run on standard-gauge track at a top speed of 90 km/h. The 2 and 4-car train configurations have been designed with the region's climate in mind. One such feature is a more powerful air conditioning system, capable of delivering sufficient cooling capacity even in extreme heat. In addition, the bogies, traction drive, brakes and doors have been fitted with special elements in order to prevent the ingress of sand.
Inspiro metro train highlights
• Fully automated, driverless operation (GoA4)
• Passenger compartment with First Class, Family Class and Single Class sections
• Lightweight aluminium carbody
• Energy saving LED lighting
• Transmission of CCTV data and passenger communication to control centre
• Fire protection requirements according to NFPA 130 / EN 45545
The trains are equipped for fully automated, driverless, and conductorless operation (GoA 4). A state-of-the-art train automation system is integrated, ensuring reliable and highly available operation. In addition, the train is equipped with further safety systems such as obstruction sensors at the end bogies and a fire detection system.
Auxiliary driver’s control desks at both ends of the train enable manual operation in emergency cases and in the depot. They are equipped with convenient touch-screen displays and all necessary controls for train operation. Read more by looking at the Project Sheet here.
