The Train Attached bridge The Insurgent protects the Ecological Reserve of the Water Pass of the Basque Manantial de Quiroga, which supplies 13 colonies of the west of the Valley of Mexico, said the general director of Railway Projects of the Secretariat of Infrastructure, Communications and Transportation (SICT), Adriana Cardona Acosta.
The structure, half a kilometer in length and a clear of 200 meters, will allow the ecological zone below and “it was very important that it did not interfere with the passage of the spring,” the official emphasized.

The construction of this bridge was executed for two years and the conclusion of the civil works is scheduled next May: “Currently work is carried out to retain the cables so that the train can continue with its trajectory.”
The Mexico-Toluca Interurban Train Bridge is located next to the fourth section of the Chapultepec forest and the University of Health.
The official said that it generates 350 sources of work and that it has “unique fierce characteristics in the world for its curvature, pending and for being part of a rail service.”
“Once the civil work is concluded, everything that is subsystems is coming: the road, the catenary, the security, signaling and communications that the train requires for its correct operation,” he explained.
The bridge, half a kilometer in length, is formed by four structures with 52 straps in total, which are divided into four groups of 13 high -caliber steel (pylons).
He said that two of the support measure 75 meters high and the other two 65 meters, which in their form of “V” It is the most efficient of engineering, since it takes into account the dynamics in the speed of the train passage with the curve.
He explained that this type of bridges is common in the road infrastructure, but when used in a railway work it gives it a unique character, which together with the road and catenary – which is where it feeds on electricity – will give movement to the train.

He added that in its design the necessary regulations regarding the earthquakes are contemplated, which will allow operating with the optimal safety conditions.
The insurgent will reach the Observatory Metro and connect directly to the Zinacantepec station, in the State of Mexico; It will have a length of 58 kilometers and seven stations.
He emphasized that the section in operation goes from Santa Fe-Zinacantepec, with a 15-minute passage frequency.
He stressed that the railroad will have advantages of time, since while the trip is 18 minutes on average, by train it is between approximately 3 and 4 minutes.
