Series 730: The train for the entire Iberian Peninsula
Spain's steady expansion of its high-speed railway has created several obstacles to seamless interoperability with the existing network due to differences in the track gauge and a lack of electrification. Series 730 is Talgo's response to Renfe's desire to overcome these obstacles.
In 2007, Renfe entered the Talgo 250 into service, a customised train designed to extend operation from the new high-speed lines to destinations on the conventional network. Excellent commercial results encouraged Renfe to request that future trains like Series 130 can operate on non-electrified lines.
To satisfy this specific need, Series 730 was modified and the train can now run on all lines in the Iberian Peninsula, connecting Madrid with Galicia, the Region of Murcia or Extremadura, and operate at 250km/h on the high-speed network.
Making trains more profitable
To optimise the use of existing infrastructure and rolling stock, this application of Talgo technology takes Series 130 as a building block, and makes it more versatile by providing two new cars fitted with diesel generators capable of powering the train's traction equipment.
- Operates at 180km/h on non-electrified Iberian gauge tracks.
- Operates at 220km/h on conventional electrified Iberian gauge tracks.
- Operates at 250km/h on standard gauge, high-speed lines.
No more obstacles
Series 730 trains are now deployed on lines linking Madrid with Coruña and Vigo. Operation is smooth, with the trains seamlessly alternating between different electrification and signalling systems and track gauges.
From Madrid to Zamora, on a track gauge of 1435mm and electrification of 25kV ac.
From Zamora to Ourense using a non-electrified 1668mm gauge line.
- From Ourense to Vigo on a 1668mm gauge line electrified at 3kV dc.
- From Ourense to A Coruña, on a 1668mm gauge line electrified at 25kV ac.
The best commercial speed
The Series 730 trains' interoperability features help to significantly reduce travel times. Faster travel is more attractive to the passenger since it increases service value, but also allows the operator to optimise the use of its assets and human resources.
- Straightforward and fast gauge transfer or switches between different electrical power supply or signalling systems.
- Natural tilting, low centre of gravity and self-guiding wheels increase speed in curves on conventional lines.
- Even distribution of doors, a low floor throughout the train and universal accessibility accelerates passenger boarding and disembarking.
