Sorry im not that knowledgable about that. What has been on the news this last month has been that sectors of the commuter network (the suburban train network) are being closed to convert them to the high speed network which will connect to guadalajara, im actually a bit confused and frustrated about this myself. And about the Priesmangoode design, what happened is Siemens original tender in the competition was the Velero, however it was given little interest due to lobbying by the Japanese with the E5 which at that point seemed like it would for sure become the winner. And Priestmangoode is only a designer so the need an actual manufacturing firm if they want their concept to come to life. They tried to interest other firms in Britain with the design but that didnt go anywhere. The Mexican transportaion secretary had already stated in the very beginging that a double decker system was preferable and since Siemens Velaro was pretty much already out of the compettition Siemens took back it's tender. Siemens then jointly (with priesmangoode) presented the concept to the Mexican transportation secretary that it could jointly manufacture the double decked Mercury design. But what really is the main aspect of why Siemens bid will probably win is because they are wiling to have the rolling stock fully manufactured in Mexico. This was in the July 2008 issue of Ferrocarril. In the end no real progress was really made in the final selection because then the Japanese and the French gave the same offer of manufacuring the trains in Mexico after Siemens came up with the concept so we still have to wait till 2011 to find out who wins / 69.235.193.67
