The AVE Class 103 is a series of AVE high speed trains for the Spanish state-run railway company RENFE.

The AVE Class 103 is as of 2008 the fastest conventional rail train in commercial use, although they don't reach their top speed until Spanish authorities deem the train control system ETCS Level 2 service-ready. Trains have been constructed by Siemens, as the first member of the company's Velaro family.

History

On 24 March 2001, Siemens won one half of RENFE's tender to supply 32 high-speed trains for the Madrid-Barcelona high-speed rail line, offering a modified version of the ICE 3 high-speed train used by German Railways (Deutsche Bahn) for its InterCityExpress service. Changes involved an up-rate to higher power (8,800 kW) for higher acceleration and top speed to cover the 651 km (405 mi) between Barcelona and Madrid in 2h30m, the ability to operate in a high range of temperatures, and a different interior.

The ICE 3 trains were a joint production with other Germany-based train manufacturers, who refused to supply parts or sell licenses to Siemens for the AVE Class 103. This caused a delay (for which Siemens eventually paid €21 million), during which Siemens had to re-develop the missing components. However, at the end of this development, Siemens had a complete high-speed train platform, which it named Velaro. The AVE Class 103 was intended as only the first member of a whole family, therefore, it was named by Siemens as the Velaro E.

The AVE Class 103 has been certified to run at 350 km/h (220 mph). During testing between Madrid and Zaragoza, on 16 July 2006, train 005 reached 403.7 km/h (250.8 mph).[1] This is both the current national rail speed record for Spain, and also the current speed record for a normal series train in standard configuration.

On 23 December 2005, RENFE ordered a further 10 identical trains (Siemens designation Velaro E2). Currently, all 26 trains from both orders have been delivered and are in service.

Specifications

The certified top speed of the AVE Class 103 is 350 km/h (217 mph), currently the highest for any train in the world, although the Alstom AGV, currently conducting extensive tests, aims for certification at 360 km/h (224 mph).

The class has distributed traction, traction equipment was moved underfloor, with powered bogies distributed in alternate carriages along the length of the train. This removes the need for driving units at either end, which AVE Class 100 and 102 have, allowing a better use of space, better energy efficiency, better acceleration at lower speeds, and better ability to climb grades. For the AVE Class 103, four of the eight cars were fitted with two powered bogies each.

Electronically, the train is actually two identical half-trains of four coaches each, each with an independent power system, apart from the active pantograph (only a single pantograph is raised on AC-fed rail lines) and a high voltage line along the entire length of the 8-car train.

The train's capacity of 404 passengers is split between three classes; with two coupled 8-car trains total capacity is therefore 808 passengers. In the end coaches (driving trailers), glass screens separate the driver and passengers, and allow passengers the same views as the driver, just as in the ICE 3 and other Velaros. The driver can turn these opaque if necessary or preferred.

In Service

The AVE Class 103 entered commercial service on 22 June 2007[2], between Madrid and the temporary end of the line to Barcelona near Tarragona.

While the trains and the tracks were commissioned for a regular top speed of 350 km/h (220 mph), the train control and signalling system necessary for such operation, ETCS Level 2, was not ready for service. Thus commercial top speed is limited to the maximum Spanish authorities approve for the line with ETCS Level 1 since 7 May 2007, 300 km/h (186 mph).[3]

ERTMS is technically capable of supporting speeds of up to 500km/h, but the signal spacing on the Madrid-Barcelona line is only sufficient to support speeds of 300km/h.

From the opening of the Córdoba-Málaga high-speed rail line on 24 December 2007, the AVE Class 103 were also used from Madrid to Málaga.

On 20 February 2008, the final section of the Madrid-Barcelona high-speed rail line into Barcelona was opened. From that day, the AVE Class 103 were used for the faster services between Madrid and Barcelona, achieving the shortest travel time of 2h38m on the non-stop runs.[4]
