RENFE Class 730


The RENFE Class 730 or S-730 is a high-speed dual-gauge, dual-voltage and hybrid trainset consisting of 11 Talgo VII tilting coaches and two power cars, used on Alvia services. The class have been nicknamed patitos, due to the shape of the train nose. They are an upgraded version of RENFE Class 130, in order to extend high-quality services to parts of Spain not on the electrified network, so these hybrid trains can run with both electric and diesel power.

Background and design

The trainsets are designed for high-speed services on conventional Iberian gauge network and standard-gauge high-speed lines; they can change gauge at low speed without stopping using Talgo's RD variable gauge system. The carriages are constructed from aluminium and incorporate the Talgo Pendular passive pendulum tilting system, are sealed against pressure differences for tunnel travel, and have underframe air conditioning, individual audio systems and video displays, rotating and reclining seats and power outlets.
Capacity in standard class is 36 seated, in first class 26 seats, end coaches have lower capacity, one coach is typically used for restaurant/sales services.
The power cars use AC traction motors controlled by IGBT inverters which include integrated auxiliary inverters. Signalling systems can include ETCS Level 2, LZB, ASFA and Ebicab900TBS.

2013 Santiago de Compostela accident

On 24 July 2013 a RENFE class S730 running as the Alvia 4155 service from Madrid to Ferrol derailed and crashed near Santiago de Compostela in north-western Spain, killing 78, out of 218 passengers on board. The cause of the accident is not yet officially determined, but the train was alleged to be traveling over twice the posted speed limit while entering a curve, due to the absence of ERTMS.

Future

Proposed Poland-Lithuania high-speed rail will be use Talgo 250 Dual that is designed for running on and lines.
