That's not how it works at all.

The Talgo 250 is an electric train. The Hybrid version is still an electric train but it has two very large identical diesel generators which provide the electrical power when there is no overhead supply.

Both "locos" are identical. If not and only one was being used the power available would be 50% and that would reduce the speed far too much.

Re: Train development news
 

Right, that seems a much better and more practical system than I previously understood it to be.

Re: Train development news
 

But the TALGO is not the train that was involved in this crash.

Re: Train development news
 

Sorry what I should have said it is not a full blown TALGO250 it is a hybrid/bastard/cockup/mishmash of train.

Re: Train development news
 

No it's not.

It is a very special variant of the Talgo 250. It is certainly not a bastard/cockup/mismash but it is a hybrid so at least you were 25% right.

Google it as I haven't got the time to explain it to you.

Re: Train development news
 

Fred, sorry you are not correct. The S730 was involved in the accident. This is NOT a TALGO.
I can assure you I am very interested in this subject and have read information and watched a lot on TV about this in Spanish and Galician, as the accident happen on my doorstep, so to speak. Given that the Galician newspaper gives us all the news I need. Like this which describes how to drive an AVLIA 730.
Así se conduce un Alvia 730
Maybe if your Spanish is not up to it then here in El Pías (in English) the headline also uses the word AVLIA.

Re: Train development news
 

I suggest you check your facts. My Spanish is well up to it by the way.

Look at http://en.wikipedia.org/wiki/Alvia

They clearly state that the train involved was a Renfe 130 which is in fact a Talgo 250H.

Also http://es.wikipedia.org/wiki/Serie_730_de_Renfe

Alvia is a train service offered by Renfe.

Talgo is a manufacturer of trains.

Also read this http://en.wikipedia.org/wiki/RENFE_Class_130 where it clearly states that the train involved was a Talgo 250.

Re: Train development news
 

So normally only one driver in the cab and he has to be able to have a pee from time to time, also he is allowed to make private phone calls in addition to those to the control centres.

Maybe they'll give some thought to having two in the drivers cab from now on, unless the trains can be fully automated during the FULL distance of their journey.

Re: Train development news
 

Oh Fred what do you not understand? :banghead:

A TALGO is not an ALVIA (class 730). Everything I have given a link to states ALVIA. But you insist it is a TALGO.
So all of the Spanish press is wrong and you are right? :hysterical:

Re: Train development news
 

Read the links!

Talgo make trains. They make the Talgo 250.

They sell them to Renfe. Renfe call them whatever they like. In this case they call it either a S130 (which is the basic Talgo 250) or an Alvia 730 (which is the hybrid).

Read this http://es.wikipedia.org/wiki/Talgo_250 where it clearly states that the Renfe 730 is a Talgo 250.

I am not going to waste any more time arguing with you if you cannot be bothered to follow up the information I gave you.

Re: Train development news
 

DD It is impossible to leave the controls for more than a short time before the breaks are applied.

Fred, I am so glad you agree it is a class 730. And that TALGO make a lot of different trains. Intrestingly the class 730 is not written about here. So how reliable is WIKI????
I will also suggest that anyone still interested in finding the true facts about this train read The RENFE site for some correct information.
This description from RENFE states this class (ALVIA 730) of train was brought in only for the Galician line and is based upon the Class 130. It is the only hybrid in service (obviously they would not call it anything else). But it is , because as I said it was political pressure that bought this service in before the line is complete. Nowhere else in Spain has a route been constructed from it’s most outer point and a gap left to Madrid and then services are running on that line. A Cock up, of a political kind.

More information can also be seen on the The main site is obviously this one. http://www.renfe.com
Look up the route between say A Coruña and Madrid you will see there are a number of trains per day.

This ALVIA (Nº 04154)
Journey taken partly on local train partly ALVIA
Journey taken partly on AVANT partly ALVIA

Of course there is also the train hotel, but that is not high speed.

Re: Train development news
 

This is from the link I posted.

The RENFE Class 130 or S-130 (Serie 130 de Renfe, manufacturer's designation Talgo 250) is a high-speed dual-gauge, dual-voltage trainset.

In order to extend high-quality services to parts of Spain not on the high-speed network RENFE acquired hybrid trains with both electric and diesel power for delivery in 2012 for use from Madrid to Murcia and Galicia, built by Talgo and Bombardier, at a cost of 78 million euro. The new trains based on the S-130 were initially coded S130H, later S730.

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.

I am not disagreeing with what you say but I was correct in originally referring to the train as a Talgo 250 when discussing the engineering aspects of it, particularly the dual gauge capability. Whatever Renfe choose to call it that doesn't alter the fact that it was designed and built by Talgo Bombardier and they call it a Talgo 250.

At the end of the day it really doesn't matter what they call it, it is the engineering that is so interesting and a really great advert for Spanish engineering.

Live streaming from the Government's commission/enquiry on the Galician Train accident.
Some interesting facts are coming out of this; plus the usual waffle.

Re: Train development news
 

El presidente de Renfe, Luis Gómez-Pomar, ha reconocido que "se advirtieron una serie de problemas" en los modelos de tren Alvia 730 en relación a la compatibilidad del sistema de señalización entre el vehículo y la vía. Es más, concretó que, el 23 de junio de 2012 se decidió, por ese motivo, cambiar el sistema utilizado para la línea Ourense-Santiago de ERTMS a ASFA (Anuncio de Señales y Frenado Automático).


Saw this in El Mundo is this what you are discussing:confused:

Still questions regarding the safety measures on that stretch of line.

Contrary to previous reports this seems to indicate that the driver did not receive a warning regarding his speed, but it does state that there are adequate speed warning signs which are very clearly visible.

When I first saw this headline, the first thing that came to my mind was substance abuse by the driver.

http://elpais.com/elpais/2013/08/07/...46_484529.html

Obviously there are tablets and tablets, however there is a question mark as to what if anything he was using his tablet for prior to the accident and wether he even saw the above mentioned warning signs, though being familiar with the track it's still surprising he didn't realize where he was until too late.
