As series 730 the designated Spanish railway company Renfe a series of 15 umspurbaren high-speed trains , which can also run on non-electrified lines. By a consortium of Talgo and Bombardier from the series 130 converted trains are also known as Talgo 250 Hybrid or as Talgo 250 H , respectively.

technology

Each train consists of two power cars, two technical end cars and nine intermediate cars of type Talgo 7 . Each of the two technical end cars contains a twelve-cylinder diesel engine from MTU Friedrichshafen , which supplies the lines of the train busbar with electrical energy via a generator , from which the traction motors of the neighboring power end are fed.

As in the vehicles of the 130 series, there are duplicate lines of the train busbar. In direct current operation, when operated under catenary, they are used to supply traction energy to the front power end, so that the pantograph is usually only raised on the rear power end. In diesel mode, one of the two lines is used for the return current from the power car to the generator, so that no traction current has to flow through the rails.

Although the term hybrid is used, the train does not meet the definition of hybrid vehicles . In addition to different drive energies, this also requires different energy stores. This means that this train is a two-motor multiple unit .

Like the original series 130 units, the trains reach a maximum speed of 250 km / h under 25 kV alternating voltage and 220 km / h under 3 kV direct voltage. In diesel mode, 180 km / h are possible. The gauging facility also corresponds to the original design, the trains can pass gauge changing facilities at a speed of 15 km / h.

The trains have 216 seats in the Turista carriage class (second class) and 48 in Preferente (first class). Cars 2 and 3 are Preferente , car 4 is the on-board bistro with two drives, the other cars are Turista . Two places in Preferente are accessible with wheelchairs . Due to the elimination of the Talgo passenger end cars, the space available has been somewhat reduced.

modification

The trains were created by converting units of the 130 series with the numbers 130 0xx, they were renamed to the 730 0xx series (730 011 to 025) while retaining the serial numbers.

During the conversion, the existing Talgo end cars were replaced by newly built technical end cars. These are supported on the neighboring Talgo wagon; due to the higher mass caused by the diesel generator unit, the end facing the power end runs on a bogie. This corresponds to a motor bogie of a power end without traction motors. Furthermore, the software of the power cars had to be adapted for diesel operation and changing the operating modes. The power end's fire alarm system was converted from smoke to thermal detectors in order to prevent exhaust gases from the diesel engines from triggering false alarms in the power end's.

history

procurement

In June 2009, the Spanish Minister of Transport, José Blanco López, described for the first time the intention to build two-power high-speed trains for high-speed traffic between the Galician cities of Santiago de Compostela and Vigo . On December 29 of the same year, the signing of a contract for 73 million euros between Renfe and the manufacturer consortium of Talgo and Bombardier was announced, which includes the conversion of 15 trains of the RENFE class 130 so that they can also be used on routes without Catenary can run.

business

The trains went into operation at the end of 2012 and will be used on connections from Madrid to the regions of Galicia and Murcia . Test drives have been taking place since summer 2011.

accident

On July 24, 2013, the Alvia 4155 train crashed with the multiple unit 730 012 at 8:42 pm on the journey from Madrid to Ferrol in a tight arc three kilometers from Santiago de Compostela . Here derailed the train set complete, it died 79 people.
