Question: One of the contractors of the Kendal Windermere Railways had also built one third of the railways in which country by 1847?
Context: The MP35 ("Maschinenpistole 35", literally "Machine Pistol 35") was a submachine gun (SMG) used by the Wehrmacht, Waffen-SS and German police both before and during World War II.  It was developed in the early 1930s by Emil Bergmann (son of Theodor Bergmann) and manufactured at the Bergmann company in Suhl (that also built one of the first submachine guns, the MP 18). Third rail railways predominantly operate in urban contexts.  Notable exceptions are (or were) mainline electrics of the former Southern Region of British Railways and a few interurban railways in the US.  In Europe top contact third rail tends to be limited to early electrified urban railways (the current conductor is normally left naked on top), contrary to North America where it usually has a protecting cover.  Obviously considered safe enough, the covered top contact conductor also appeared at most North American systems built relatively recently.  Modern European systems predominantly make use of bottom or side contact power rails. The Edirne cut-off is a 80 km long rail line from Pehlivanköy, Turkey to Svilengrad, Bulgaria.  The line was built in 1971 by the Turkish State Railways in order to avoid crossing the border with Greece, on the former Oriental Railway's main line, in order to get to Edirne.  The Hellenic Railways Organisation (OSE) also built a cut-off from Neo Vyssa to Marasia in the same year.  These two new rail lines led to the abandonment of the former CO main line in Edirne as well as the Karaağaç Railway Station. Windermere is the largest natural lake in England.  It is a ribbon lake formed in a glacial trough after the retreat of ice at the start of the current interglacial period.  It has been one of the country's most popular places for holidays and summer homes since the arrival of the Kendal and Windermere Railway's branch line in 1847.  Historically forming part of the border between Lancashire and Westmorland, it is now within the county of Cumbria and the Lake District National Park. Sheffield is the most geographically diverse city in England .  The city nestles in a natural amphitheatre created by a number of hills forming the eastern foothills of the Pennines, and the confluence of five rivers: Don, Sheaf, Rivelin, Loxley and Porter.  As such, much of the city is built on hillsides, with views into the city centre or out to the countryside.  The city is roughly one third urban, one third rural and one third in the Peak District.  At its lowest point the city stands just 29 metres above sea level at Blackburn Meadows on the Rotherham border, rising up to over 500 m in some parts of the city to a peak of 548m at High Stones on the Derbyshire border; however, 89% of the housing in the city is between 100 and 200 metres above sea level.  Over 95% of the population resides in the main urban area. Nawab Khair Andesh Khan Sani was son of Nawab Khair Andesh Khan and belonged the illustrious family of the Kamboh Nawabs of Meerut.  His original name was Muhammad Masih.  He held a manasab of five thousand and the title of "Nek Andesh Khan" under Mughal Emperor Aurangzeb.  Later under Emperor Bahadur Shah, he held six thousand mansab and received a title of Khair Andesh Khan.  Khair Andesh Khan Sani built Khair Nagar in Bareilly and also built one Idgah, one Mubarak palace and many other buildings in Khair Nagar.  He also waged war against king of Bundelkhand and reduced him to subjugation.  His son was given the title of "Nek Andesh Khan" and a big fief or "Jagir" in Bareilly.  His one brother Nawab Khairiyat Andesh Khan held a mansab of five thousand and remained governor of Kashmir where he constructed a Bazar known as Nawab Bazar.  His second brother also got the title of "Kheir Andesh Khan Salas" during the reign of emperor Ahmed Shah Durani and also held the governorship of Kashmir. Hotel Windermere was a hotel in Hyde Park, Chicago, United States, located at 56th Street and Cornell Avenue.  It was built in 1892 for the Columbian Exposition.  In 1924 it was rebuilt with a West and East hotel under Rapp & Rapp, who also built the Chicago Theatre and the Tivoli Theatre.  The 12-storey hotel had 482 guest rooms and 200 apartments and had an underground tunnel connecting the two hotels.  Over the years Windermere East attracted guests such as John Rockefeller, Philip Roth and American football teams.  The Windermere's brunch was a favorite of Adrienne Rogers.  Known jovially as the Amelia Earhart of Chicago's southern lakefront, Adrienne shocked sunbathers, swimmers and lifeguards alike with intermittent landings of her seaplane, The Lil Randy, onto the 57th street beach.  When questioned about her aerial commute to the Windermere's infamous brunch sessions, Adrienne simply replied, "I'll be damned if I miss my spicy fish."  Windermere West was demolished in 1959 to make way for a parking lot, and in 1981 Windermere East was converted into apartments and placed on the National Register of Historic Places a year later under the title Hotel Windermere East. The Kendal and Windermere Railway is a railway in Cumbria in north-west England.  It was built as a railway from the Lancaster and Carlisle Railway at Oxenholme via Kendal to near Windermere, opening fully in April 1847.  The engineer was Joseph Locke and the partnership of contractors consisted of Thomas Brassey, William Mackenzie, Robert Stephenson and George Heald.  It remains open, albeit in much simplified form, as the Windermere Branch Line. In Norway, a number of main lines were in the 19th century built with narrow gauge, , to save cost in a sparsely populated mountainous country.  This included Norway's first own long-distance line, the Røros Line, connecting Oslo and Trondheim, 1877.  Some secondary railways also had this gauge.  These railways have been rebuilt to standard gauge or closed down.  Some private railways had and one had .  A few railways partly still are operated as museum railways, specifically the Thamshavn Line, Urskog–Høland Line and the Setesdal Line.  The Trondheim Tramway is also narrow gauge. Thomas Brassey (7 November 1805 – 8 December 1870) was an English civil engineering contractor and manufacturer of building materials who was responsible for building much of the world's railways in the 19th century.  By 1847, he had built about one-third of the railways in Britain, and by time of his death in 1870 he had built one in every twenty miles of railway in the world.  This included three-quarters of the lines in France, major lines in many other European countries and in Canada, Australia, South America and India.  He also built the structures associated with those railways, including docks, bridges, viaducts, stations, tunnels and drainage works.
