Fitchburg Railroad
The Fitchburg Railroad is a former railroad company, which built a railroad line across northern Massachusetts, United States, leading to and through the Hoosac Tunnel. The Fitchburg was leased to the Boston and Maine Railroad in 1900. The main line from Boston to Fitchburg is now operated as the MBTA Fitchburg Line; Pan Am Railways runs freight service on some other portions. History Early history A horse-drawn railroad from Boston to Brattleboro, Vermont, via Fitchburg was proposed in 1828. The Charlestown Branch Railroad was incorporated April 4, 1835, as a short branch from the Boston and Lowell Railroad near Lechemere Point in Cambridge, across the Miller's River to the Charlestown waterfront, ending at Swett's Wharf (Sweet's Wharf in some sources) right before the Charlestown Navy Yard. It opened in January 1840 with horse-drawn trains. The Fitchburg Railroad was incorporated March 3, 1842, to run from Boston to Fitchburg, and bought land next to the Charlestown Bran ...

Tactile Paving
Tactile paving (also called tenji blocks, truncated domes, detectable warnings, tactile tiles, tactile ground surface indicators, tactile walking surface indicators, or detectable warning surfaces) is a system of textured ground surface indicators found on stairs and railway station platforms, to assist pedestrians who are vision impaired. Tactile warnings provide a distinctive surface pattern of truncated domes, cones or bars, detectable by a long cane or underfoot, which are used to alert the vision-impaired of approaching streets and hazardous surface or grade changes. There is disagreement between the design and user community as to whether installing the aid inside buildings may cause a tripping hazard. A system of tactile paving was first instituted in Japan at pedestrian crossings and other hazardous road situations; the United Kingdom, Australia and the United States picked up the standard in the early 1990s. Canada started incorporating them into transportation first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Works Progress Administration
The Works Progress Administration (WPA; renamed in 1939 as the Work Projects Administration) was an American New Deal agency that employed millions of jobseekers (mostly men who were not formally educated) to carry out public works projects, including the construction of public buildings and roads. It was set up on May 6, 1935, by presidential order, as a key part of the Second New Deal. The WPA's first appropriation in 1935 was $4.9 billion (about $15 per person in the U.S., around 6.7 percent of the 1935 GDP). Headed by Harry Hopkins, the WPA supplied paid jobs to the unemployed during the Great Depression in the United States, while building up the public infrastructure of the US, such as parks, schools, and roads. Most of the jobs were in construction, building more than 620,000 miles (1,000,000 km) of streets and over 10,000 bridges, in addition to many airports and much housing. The largest single project of the WPA was the Tennessee Valley Authority. At its peak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Boston And Maine Railroad
The Boston and Maine Railroad was a U.S. Class I railroad in northern New England. Originally chartered in 1835, it became part of what was the Pan Am Railways network in 1983 (most of which was purchased by CSX in 2022). At the end of 1970, B&M operated on of track, not including Springfield Terminal. That year it reported 2,744 million ton-miles of revenue freight and 92 million passenger-miles. History The Andover and Wilmington Railroad was incorporated March 15, 1833, to build a branch from the Boston and Lowell Railroad at Wilmington, Massachusetts, north to Andover, Massachusetts. The line opened to Andover on August 8, 1836. The name was changed to the Andover and Haverhill Railroad on April 18, 1837, reflecting plans to build further to Haverhill, Massachusetts (opened later that year), and yet further to Portland, Maine, with renaming to the Boston and Portland Railroad on April 3, 1839, opening to the New Hampshire state line in 1840.

Massachusetts Central Railroad
The Massachusetts Central Railroad is a short line railroad in western Massachusetts, United States. It was established in 1975 to provide railroad transportation services on portions of the Boston & Maine Wheelwright Branch in and around their trackage in Bondsville (a village of Palmer) and Ware, and later between Palmer and South Barre on the old Right of Way (ROW) of the Ware River Railroad. History The old Ware River Railroad was an independent line that ran from Palmer to the Cheshire Railroad in Winchendon and was built in 1868. The first section, from Palmer to Gilbertville, opened in 1870, and the rest three years later. Until 1873 it was leased to and operated by the New London Northern Railroad. It was eventually taken over by the Boston and Albany Railroad and run as its Winchendon Branch. The B&A wanted to run the Ware River Line in conjunction with the Monadnock Railroad in order to gain access to the resort areas of Peterborough, New Hampshire. When the B&A ...

Pedro II Of Brazil
Don (honorific), Dom PedroII (2 December 1825 – 5 December 1891), nicknamed "the Magnanimity, Magnanimous" ( pt, O Magnânimo), was the List of monarchs of Brazil, second and last monarch of the Empire of Brazil, reigning for over 58 years. He was born in Rio de Janeiro, the seventh child of Emperor Dom Pedro I of Brazil and Empress Dona Maria Leopoldina and thus a member of the Brazilian branch of the House of Braganza. His father's Abdication of Pedro I of Brazil, abrupt abdication and departure to Europe in 1831 left the five-year-old as emperor and led to a grim and lonely childhood and adolescence, obliged to spend his time studying in preparation for rule. His experiences with court intrigues and political disputes during this period greatly affected his later character; he grew into a man with a strong sense of duty and devotion toward his country and his people, yet increasingly resentful of his role as monarch. Pedro II inherited an empire on the verge of disint ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Track Circuit
A track circuit is an electrical device used to prove the absence of a train on rail tracks to signallers and control relevant signals. An alternative to track circuits are axle counters. Principles and operation The basic principle behind the track circuit lies in the connection of the two rails by the wheels and axle of locomotives and rolling stock to short an electrical circuit. This circuit is monitored by electrical equipment to detect the absence of the trains. Since this is a safety appliance, fail-safe operation is crucial. Hence the circuit is designed to indicate the presence of a train when failures occur. On the other hand, false occupancy readings are disruptive to railway operations and must be minimized. Track circuits allow railway signalling systems to operate semi-automatically, by displaying signals for trains to slow or stop in the presence of occupied track ahead of them. They help prevent Train dispatcher, dispatchers and Manual block, operators from ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Robinson (inventor)
William Robinson (November 22, 1840 – January 2, 1921) was an American inventor, electrical engineer, mechanical engineer and businessman. He invented the first track circuit used in railway signaling, a major development that improved railroad safety and efficiency. Early life and education William Robinson was born in Ireland on November 22, 1840. He came to the United States as a boy and lived in Brooklyn, New York for much of his adult life.
