Monterrey Metro Switches to Biofuel

Monterrey, Mexico's metro to run on biofuel

MONTERREY, Mexico, June 28, 2006 (AFP) - The Monterrey, Mexico metro will become the first subway system in Latin America to run on biofuel, Metrorrey director Rolando Valle announced.

"We will set a historic milestone in public transport by having the first subway that runs on biogas energy, which is produced by controlled decomposition of organic waste," Valle told reporters Tuesday.

He said the subway system in Mexico's third-largest city, serving 180,000 commuters a day, will switch over from electricity to biofuel for 82 percent of its energy needs, providing a savings of some 130,000 dollars per year (eight percent).

Valle did not say when he expected the city's fuel switchover to take place.

switch over from electricity to biofuel? are they serious? are we sure this isn't a bad translation? the system is fully electrified with the electric power infrastructure now--probably suspended wire over the track; they would need all new rolling stock to do this--the easiest way to convert would simply be to change the way they generate the electrical power. check out the Calgary light rail, it is electrically powered but i've heard its all generated by a giant windfarm outside the city.

The Monterrey Metro, officially known as Metrorrey has two lines with 32 stations.

Line 1, which opened on April 21, 1991 has 19 stations, runs through the center of the city from the north-west to the eastern part of the Monterrey Metropolitan Area. The line is 18.5 km long, runs parallel to the former 1887 Topo Chico tramline and is grade-separated as it runs on an elevated structure. A complete ride along this line takes about 27 minutes[citation needed]. Line 1 is linked to line 2 at Cuauhtémoc station, located downtown.

Line 2 has 13 stations and is also fully grade-separated, partially on an aerial structure and partially subterranean. The first six-station segment opened in 1994, was 4.5 km long and runs underground. Construction on a USD 200 million expansion of Line 2 began in August 2005. The first segment of the expansion opened in October 2007 and added an additional three stations to the line. The second segment of the expansion was inaugurated on October 9, 2008 by Nuevo León Governor Natividad González Parás and Mexican president Felipe Calderón and added an additional four stations to the line. This last segment runs on an aerial structure in the center of Avenida Universidad. The completed 12.5 km route runs from Sendero to the Macroplaza with a station at the Universidad Autónoma de Nuevo León.

There are plans for a "Line 3" of the Monterrey Metro. "Line 3" would have a length of 7.5 kilometres and a total of 9 stations, spanning from the Line 2 terminus at General Zaragoza northeast to Hospital Metropolitano, mostly on an elevated structure.

It seems like line 3 is just an extention of the existing line 2. Will the technology of the new line be that different so that they have to keep them as separated lines?

It will be segregated so you have to change trains. Here is a map of how line3 will look like.

CAF seals Monterrey metro vehicle deal
Thursday, July 31, 2014



THE government of the Mexican state of Nuevo León has awarded CAF, Spain, a Peso 3.26bn ($US 251m) contract to supply and maintain 22 trains for Line 3 of the Monterrey metro

In addition to the 20 year maintenance contract, CAF will provide spare parts for two years, while the contract includes an option for the purchase of four more trains for the network's operator, Mettrorey Public Transport.

The 8km Line 3 is currently under construction after the state government awarded a consortium of Garza Parke, Moyeda Construction and Alstom a Peso 2.17bn contract in November 2013. Mexico's Ministry of Communications and Transport (SCT) and the Nuevo León government signed a collaboration agreement for the project, which is budgeted at Pesos 5.6bn, in February 2013.

The line will consist of a 7km elevated section, an 800m tunnel as well as a 200m at-grade section running from Zaragoza to Metropolitan Hospital. The line will have eight stations, and will serve around 280,000 passengers per day, with the state government setting an ambitious opening date of August 2015.

Monterrey's existing metro network consists of the 18.5km east-west Line 1, which opened in 1991, and the 4.5km north-south Line 2, which opened in 1994, and was extended north by 8.5km in 2008.

Info. proporcionada por Concreto.acero

PUES, ASÍ ES COMO SE ESTA HACIENDO EN LOS CASI 300mts. DE TUNEL





1.-Después del mejoramiento del terreno con inyecciones y abatido el nivel freático y construida la trabe de borde, se deberán instalar tubos de enfilaje
2.-En cada avance de excavación, a la sección recién excavada se le colocará una capa sello de concreto lanzado. mientras que la zapata intermedia deberá ser cubierta en un 60%.
A las secciones excavadas con anterioridad se les lanzará una segunda capa de concreto lanzado .en lo que respecta a la zapata intermedia esta tendrá que ser conformada en su totalidad.
3.-Una vez que el frente de excavación se encuentre a 30m
de distancia, se podrá comenzar con la construcción de las zapatas definitivas y cubeta, ambas correspondientes al revestimiento primario, para lo cual se excavará la parte central de la zona de banqueo.
4.-Colocar membrana impermeable
5.-colocar el acero de refuerzo en las zapatas intermedias-posicionar la cimbra y colado de concretoy revestimiento secundario
6.-Armado de refuezo y colado de la cubeta y revestimiento secundario


DESPUES OTRRS 300mts CAJON A CIELO ABIERTO



Y LUEGO LO QUE SERÁ LA RAMPA DE SALIDA EN CONSTITUCION



Saludos
