TheRenfe Class 102orS-102[note 1](nicknamed "Pato"in Spanish, because of its nose that looks like the beak of aduck) is ahigh-speed trainused for theAVEservice and operated in Spain by the state-run railway companyRenfe,and based onBombardier Transportation's power car technology. Outside AVE service,Talgomarkets this train as theTalgo 350.[1]

Further production of closely related trains, differing in seating arrangement, resulted in theS-112.

Background, design and orders

[edit]

The AVE Class 102 was constructed byTalgowithAdtranz(laterBombardier Transportation) providing the power car technology. It was primarily designed for the Madrid-Barcelona line.

The trainsets consist of Talgo passenger cars modified in order to allow speeds of up to 350 km/h (220 mph) with power cars at each end. However, its certified maximum operating speed is 330 km/h (210 mph) due to the limits of its eight 1,000 kW (1,300 hp) motors. The trainsets can consist of up to 12Talgo series VIIcoaches.

Power unit with a 'beak'

The train is nicknamedPato,Spanish for duck, due to the aerodynamic design of the power cars resembling a beak. The beak design reduces noise created by air resistance at top speeds.

The series trains were intended for a top speed of 330 km/h (210 mph).[2]This top speed was supposed to be enough to fulfill the tender condition of a two-and-a-half-hour travel time between Madrid and Barcelona. Experts ascribe this reduction compared to original plans to budgetary reasons, which derive from the strongly increased power requirements at even higher speeds.[3]

Renfe Class 112

[edit]

Renfe's original order in 2004 was for 16 series units, delivery of which began in 2004. A follow-up order for 30 similar trains to be delivered in 2008-2010 and designated as class 112 (S-112). The first production unit was unveiled in June 2010.[4]

Introduction, testing and operations

[edit]

In trials with the prototype unit (later used by track authorityADIFas test train Class 330), on 11 October 2002, 362 km/h (225 mph) was achieved.[5]

Type approval tests began in 2004. Type approval requires test runs at speeds 10% above the desired permitted top speed. During the approval tests, a new record of 365 km/h (227 mph) was achieved in the early hours of 26 June 2004.[6]

After the successful completion of the tests, the first eight series units commenced operation on the Madrid-Zaragoza-Lleida line on 26 February 2005.[7]Initially, maximum service speed was restricted to 200 km/h (120 mph), due to problems with the train control and signalling system on the line.

After the commissioning of the train control systemETCS L1,the top speed was increased in steps.[8]Since 7 May 2007,[9]the trains travel with the top speed targeted for the time being[7]300 km/h (190 mph).

After the stabilisation of the train control systemETCS L2,the trains may cover the distance of 621 km between Madrid and Barcelona in about 2 hours 30 minutes, with a top speed of 330 km/h (210 mph).[10]However, presently, non-stop runs are carried by theClass 103trains, while the S-102 are deployed for runs with intermediate stops, with travel times between 2 hours 57 minutes and 3 hours 23 minutes.[8]

Export

[edit]
Talgo 350 for Haramain HSR

Talgo 350 trains based on the Class 102 design are being used on theHaramain high-speed railwayline inSaudi Arabiaunder a contract announced in October 2011. The service became operational in September 2018.[11]
