It includes seventeen vertical ventilation airflows, as well as thirteen emergency exits located every 600 m. The tunnel was designed following ballastless tracks technology (Protection from vibration and noise). It includes three intermediate stations: Sol, in the city centre of the pulsing and lively Madrid, Alonso Martínez and Nuevos Ministerios. The length is 7.5 km, whereas the total distance of the new infrastructure is 8.254 km. Second tunnel is located at the west of the first one and has a stop in “La Puerta del Sol”.
This corridor consists in a double tunnel with two lanes each other and a third one for AVE (High Speed Train). These are the main stations of Madrid in terms of number of passengers. The railway tunnels Atocha – Chamartin, popularly known as “Túneles de la Risa”, connect Atocha-Cercanías and Chamartin stations. Replacement of the CO and NO2 detection equipment for DURGAS system. In addition, we opted for neutral and transparent railings.November 2018. Both overpasses have their own identity, but the concrete supports are what ties them in nicely, as well as the colour scheme.
The V-shaped concrete intermediate supports all are identical and play a big role in the overall appearance of the underpass. The retaining walls of the underpass will be clad with red/brownish tiles in vertical stretcher bond. In other words, the underpass is one gateway with two different faces. When the underpass is completed, people exiting the city centre towards the northwest will see a green overpass that signals the vicinity of rural life, whereas those traveling towards the south will see a rather urban-looking overpass with a timber slat railing. Our design emphasises the differences in the areas on either sides of the underpass: the rural world of Langedijk on the north west and the urban area of Heerhugowaard south of the railway tracks. A wide flight of stairs offers pedestrians a quick route towards the station. The area in between both bridge decks is designed as a high-end balcony, that connects the two levels of the underpass. The railway overpass and road overpass are only five metres apart. The relatively low retaining walls and their outwardly tilted positioning create an underpass with plenty of light and clear views. Both axes are clearly visible in our design. The underpass is an intersection of two green axes: the Zuidtangent itself and the wildlife connection right alongside the railway tracks. We designed a spacious underpass that suits the municipality’s sustainability ambitions. We were commissioned for the overall design of this double overpass, based on the masterplan for the entire area as drawn up by KuiperCompagnons.
The current level crossing will be changed into a double underpass with the existing railway track passing above as well as an overpass for road traffic. The new Zuidtangent should become a lively and appealing connection. Part of the plan is to refurbish the Zuidtangent, a main road connecting the area with other parts of town. The Dutch municipality of Dijk en Waard is aiming to increase the accessibility, safety and appeal of the area around the railway station.
