Conference "The Mountain Cavern. The first railway tunnel in Spain, scotch bonnet shell Proxim Hill "by the engineer Mr. Xavier NUBIOLA, Wednesday 11 February 2015 at 18:00 pm. Within the cycle Classrooms Senior Extension of the University Pompeu Fabra, will take place at Mataroní Development, No. 11 New Street Mataró.
The research is conducted on Xavier NUBIOLA tunnel explains how Proxim Proxim scotch bonnet shell Hill was before the wear caused by the quarry, technical issues such as how drilled railway tunnel, the design of telecommunications essential to communicate between the stations as early twentieth century was extended tunnel virtually untouched its external aspect, as the southern mouth of the tunnel destroy the republican retirement in 1939, and as the train impacted the growth and Proxim industrialization. We publish here a part of the book (Chapter 2), with the permission of the author, which was presented during the 2012 Fair Railway.
To build the first railway line in Spain between Barcelona and kill the coast, the Hill of Proxim scotch bonnet shell was pierced by a tunnel, and for this reason since popularly known as "The Mountain Cavern." This work was the most important of the line, along with the bridge over the river Besòs. According to the literature of the time, the cost of the tunnel was 62,500 duros (= 312.500 pesetas = 1.875 euros), scotch bonnet shell this figure was described as exaggerated by the Board, so that the phrase "To be more expensive than Proxim Tunnel "was during a time of comparison (DM: A report of the centenary of the railway. Magazine scotch bonnet shell Argentina Fiesta Mayor, 1948). The dimensions of the tunnel are shown in the two tables below, according to the literature, according to current scotch bonnet shell data provided by ADIF: Dimensions Tunnel Proxim, according to the literature. - Year 1848 - Dimension 500 feet long * 139.30 Metres Width Height scotch bonnet shell 24 27 7,52 6,69 * 1 foot = 0.2786 meters Spanish
Dimensions Tunnel Proxim, according ADIF plans * (m) Initial Dimension (1848) Eixample (1900) Current (1940) Length (including walls) 142,50 142,50 134,00 7,55 8,25 Width 8 25 Height 1 (Pla key ways) 6,05 6,05 6,05 Height 2 (Solera key) 6.66 6.66 6.66 * have made the following estimates: Loss length of the tunnel height = 8.5 m-plane = 0.61 m hearth pathways
For legal reasons, the initial width of 7.55 meters of tunnel had to allow for double track railway that time, but only settled via an offset to the side of mountain. But when in 1899 it was decided to double the track, it is necessary scotch bonnet shell to widen the tunnel 70 centimeters to meet the new requirements of the trains. The tunnel Proxim was the first Spanish railway tunnel was opened on 28 October 1848, while the Tunnel End in Arenys de Mar, in the prolongation of killing Arenys de Mar, 195 meters length, opened on 10 January 1857, was the second rail tunnel in Spain (MAYNAR, Melis and others. Inventory tunnel Ferroviarios Spain. Fundación de los Ferrocarriles Españoles, Editions Twelve Streets, 2005). The story about the construction of the railway line and tunnel, can now be reviewed in the light of the Archives of William Mackenzie, English contractor's work, since 1994 can be found on the Institute of Civil Engineers of London (Valle BOTEY, Cecilia. The William Mackenzie archivo y los Ferrocarriles Españoles primeros. Biada Circle Historic Michael, 2009). scotch bonnet shell
On 10 April 1845, the Board requested the railway State Government granting short, presenting the project led by the English engineer Joseph Locke (Fig. 5), and the rules of the Company. Locke had a reputation built with high economic track railway embankments, even at the expense of steep slopes in some sections to avoid costly works. Thus, it is not surprising that in granting definitive Royal Order (RO) July 27 (ANC background TBF / 258, 85-23), authorizing the start of work to build the railway, but some "Prevention" which among other things relating to the reduction of embankments and slopes to avoid the barrier effect posed by rail, specifically regarding the tunnel says:
