Problem:Question: Does Norfolk Southern Railway still own the Lehigh line? Passage 1:Sited at the confluence of the rapidly flowing Lehigh River's waters with the more stately waters of the deeper wider Delaware, Easton became a major commercial center during the canal and railroad periods of the 19th century, when it would become a transportation hub for the eastern steel industry. The Delaware Canal, was quickly built soon after the lower Lehigh Canal (1818) became effective in regularly and reliably delivering much needed anthracite coal, into more settled lands along the rivers. And eventually the Morris would also serve to connect the rapidly developing Coal Regions to the north and west, to the fuel starved iron works to the west, the commercial port of Philadelphia to the south, and to the many home owners seeking fuel for heat within Pennsylvania, Maryland, New Jersey, Delaware and New York. Seeing other ways of exploiting the new fuel source, other entrepreneurs quickly moved to connect across the Delaware River reaching into the New York City area to the east via a connection with the Morris Canal in Phillipsburg, New Jersey, so the town became a canal nexus or hub from which the Coal from Mauch Chunk reached the world. The early railroads were often built to parallel and speed shipping along transportation corridors, and by the late 1860s the Lehigh and Susquehanna Railroad (LH&S) and Lehigh Valley Railroad (LVRR) were built to augment the bulk traffic through the canals and provide lucrative passenger travel services. The LVRR, known as 'the Black Diamond Line' would boast the twice daily "Black Diamond Express" daily passenger trains to and from New York City and Buffalo, New York via Easton. The Central Railroad of New Jersey (CNJ), would lease and operate the LH&S tracks from the 1870s until the Conrail consolidations absorbed both the Central Railroad of New Jersey and Lehigh Valley Railroad in 1966. Today, the Lehigh Valley Railroad's main line is the only major rail line that goes through Easton and is now known as the Lehigh Line; the Lehigh Line was bought by the Norfolk Southern Railway in 1999.
 Passage 2:With its 2,000 religious places – 1,600 Buddhist temples and 400 Shinto shrines, as well as palaces, gardens and architecture intact – it is one of the best preserved cities in Japan. Among the most famous temples in Japan are Kiyomizu-dera, a magnificent wooden temple supported by pillars off the slope of a mountain; Kinkaku-ji, the Temple of the Golden Pavilion; Ginkaku-ji, the Temple of the Silver Pavilion; and Ryōan-ji, famous for its rock garden. The Heian Jingū is a Shinto shrine, built in 1895, celebrating the Imperial family and commemorating the first and last emperors to reside in Kyoto. Three special sites have connections to the imperial family: the Kyoto Gyoen area including the Kyoto Imperial Palace and Sentō Imperial Palace, homes of the Emperors of Japan for many centuries; Katsura Imperial Villa, one of the nation's finest architectural treasures; and Shugaku-in Imperial Villa, one of its best Japanese gardens. In addition, the temple of Sennyu-ji houses the tombs of the emperors from Shijō to Kōmei.
 Passage 3:Denver had long been a hotbed of Denver Bears/Zephyrs minor league baseball and many in the area desired a Major League team. Following the Pittsburgh drug trials, an unsuccessful attempt was made to purchase the Pittsburgh Pirates and relocate them. However, in 1991, as part of Major League Baseball's two-team expansion (along with the Florida (now Miami) Marlins), an ownership group representing Denver led by John Antonucci and Michael I. Monus was granted a franchise; they took the name "Rockies" due to Denver's proximity to the Rocky Mountains, which is reflected in their logo; the name was previously used by the city's first NHL team (who are now the New Jersey Devils). Monus and Antonucci were forced to drop out in 1992 after Monus' reputation was ruined by an accounting scandal. Trucking magnate Jerry McMorris stepped in at the 11th hour to save the franchise, allowing the team to begin play in 1993. The Rockies shared Mile High Stadium (which had originally been built for the Bears) with the National Football League (NFL)'s Denver Broncos for their first two seasons while Coors Field was constructed. It was completed for the 1995 Major League Baseball season.
