São Paulo Railway Company
Template:Short description Template:Use dmy dates Template:Infobox rail The São Paulo Railway Company (SPR, nickname Ingleza, transl.: The English<ref name="Piassagüera">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>) was a privately owned British railway company in Brazil, which operated the Template:RailGauge gauge railway from the seaport at Santos via São Paulo to Jundiaí. The company was nationalised in 1946 and became the Estrada de Ferro Santos-Jundiaí.
The São Paulo Railway consists of three parts:
- The Template:Convert long adhesion railway at the coast from Santos to Piaçaguera near Cubatão
- The Template:Convert long steep grade from Piaçaguera to Paranapiacaba
- The adhesion railway on the plateau from Paranapiacaba via São Paulo to Jundiaí
Three different systems were used to climb the steep grade between Piaçaguera and Paranapiacaba:
- A four section cable railway with stationary steam engines, in use from 1867 till 1970, called Serra Velha, transl.: Old Mountain
- A five section cable railway with stationary steam engines, in use from 1901 till 1982, called Serra Nova, transl.: New Mountain
- An electrified rack-and-adhesion railway built on the right of way of the abandoned Serra Velha opened in 1974, called Sistema Cremalheira-Aderência, transl.: System Rack-and-adhesion
Planning
In 1859, a group of people led by the Barão de Mauá convinced the Brazilian government that it was important to construct a railroad connecting São Paulo to the seaport at Santos. The main purpose of the project was the transport of the coffee grown on the inland plateau to the Atlantic coast for export. The biggest difficulty was the task to overcome the steep east slope of the 800-meter high Serra do Mar, which was considered to be nearly impracticable. Therefore, Barão de Mauá asked Britain to clarify the feasibility of a railway line for locomotive hauled trains within a budget limit of 200,000 £. The greatest technician for this subject was consulted: Scottish railroad engineer James Brunlees.<ref name="HSPR">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="Gateway to Brazil">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Brunlees visited Brazil and considered that the project was feasible. He recommended engineer Daniel Makinson Fox to Barão de Mauá for the execution of the project. Fox was at that time only 26 years old but had already experience in the construction of railways through the mountains of northern Wales and the hillsides of the Pyrenees. He realised that the railway could only climb the slope in the Serra do Mar if a Template:Convert long incline system was built. An adhesion railway would have used Template:Convert to overcome the slope and would have also overrun the 200,000 £ budget.<ref name="Gateway to Brazil"/>
Construction
Daniel Fox's proposal for the railway line from Santos to Jundiaí including the incline system was approved by Brunlees and the São Paulo Railway Company (SPR) was established to build the railway system and operate it for 90 years.<ref name="Museu">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Since the capital of the company was mainly British also the official company name was in English, not Portuguese. The railway company contracted with Robert Sharpe & Sons to acquire the land, execute the works and supply all rolling stock and plant.<ref name=graham>Template:Cite book</ref>
Construction on the Template:Convert long adhesion railway Santos – Piaçaguera began on 15 March 1860 and on the incline system in the year 1861.<ref name="Museu" />
The road was constructed without explosives since it was felt that the slopes were very unstable. The rock was excavated only with plug and feathers. Embankments of Template:Convert in height were constructed to protect the tracks from the frequent torrential rains in the area, which used about Template:Convert rocks. The line did not have any tunnels.<ref name="Gateway to Brazil"/>
In spite of all the difficulties, the construction finished 10 months ahead of the date specified in the contract, which was eight years. The São Paulo Railway was opened on 1867-02-16.<ref name="Gateway to Brazil"/>
Serra Velha – the first incline system
The part of the route climbing the Serra do Mar consisted of four 10.3% grade cable railway sections with the following length:<ref name="HSPR" />
- section 1: Template:Convert
- section 2: Template:Convert
- section 3: Template:Convert
- section 4: Template:Convert
At each section the wagons were attached to a steel wire rope with the help of a specially fitted brake van called Serrabreque (transl.: Hill Brake).<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The steel cable was driven by a stationary steam winding engine at the top end of the section, where a Template:Convert extension with a 1.3% grade was also fitted, so that the wagons could be led to the next section.<ref name="HSPR" />
The incline system was later called Serra Velha (transl.: Old Mountain) to distinguish it from the later built second incline system called Serra Nova.
Serra Nova – the second incline system
The large volume of coffee shipments and the growth of the cities in the São Paulo region required more transport capacity. Therefore, the construction of a second incline system started in 1895. The new line ran parallel to the already existing one in about Template:Convert distance. It had five sections using continuous steel wire ropes which were moved by stationary Template:Convert steam engines. Each section was about Template:Convert long and had a grade of 8%. Two to three wagons were coupled to the rope with the help of small locomotives fitted with grip engaging with the cable. These locomotives were also able to handle the wagons in the terminal station and between the sections so that the operation of the incline system was facilitated. The locomotives have been called Locobreque (transl.: Brake locomotives). In case the weight of the wagons to be lifted was too heavy compared to the wagons lowered at the same time, tank cars filled with water were used to counterbalance the system. The incline system was used in revenue service till 1982.<ref name="Museu" />

Protests
In 1889, the first protests were made against the British monopoly over the route to Porto de Santos, which culminated in the construction of Mairinque–Santos in 1937, by the Template:Ill.
Nationalisation
On 1946-09-13, the railroad was nationalised by the Brazilian government, and renamed the Estrada de Ferro Santos-Jundiaí, and on 1948-09-27, it was merged with most of the other Brazilian railways into the Rede Ferroviária Federal SA (RFFSA).
Sistema Cremalheira-Aderência – the Rack-and-adhesion railway
In the 1970s (well after it had been renamed), the haulage system was replaced by an Abt rack system with a maximum gradient of 10.4 %, which was installed by Japanese firm Marubeni. The locomotives for this changeover were constructed by Hitachi with the help of SLM. They work with 3 kV DC supplied by overhead lines.
Starting from 2012, the original Hitachi locomotives were replaced by seven new-built machines supplied by Stadler.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
