Horsecar
A horsecar, horse-drawn tram, horse-drawn streetcar (U.S.), or horse-drawn railway (historical), is an animal-powered (usually horse) tram or streetcar. Summary The horse-drawn tram (horsecar) was an early form of public rail transport, which developed out of industrial haulage routes that had long been in existence, and from the omnibus routes that first ran on public streets in the 1820s{{{citation needed, date=February 2022, using the newly improved iron or steel rail or ' tramway'. They were local versions of the stagecoach lines and picked up and dropped off passengers on a regular route, without the need to be pre-hired. Horsecars on tramlines were an improvement over the omnibus, because the low rolling resistance of metal wheels on iron or steel rails (usually grooved from 1852 on) allowed the animals to haul a greater load for a given effort than the omnibus, and gave a smoother ride. The horse-drawn streetcar combined the low cost, flexibility, and safety of an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cambridge Railroad
The Cambridge Railroad (also known as the Cambridge Horse Railroad) was the first street railway in the Boston, Massachusetts area, linking Harvard Square in Cambridge to Cambridge Street and Grove Street in Boston's West End, via Massachusetts Avenue, Main Street and the West Boston Bridge. The company was chartered and incorporated May 25, 1853, and started construction September 1, 1855. The horsecar line opened between West Cedar Street (just east of Charles Street) and Central Square on March 26, 1856. Extensions opened in April to Brattle House in Brattle Square and to Revere House in Bowdoin Square. A further extension to Mount Auburn Cemetery opened soon after, as did a branch to Porter Square. The connecting Watertown Horse Railroad opened on April 27, 1857. The Porter Square branch was extended to the border of West Cambridge (now Arlington); there it met the West Cambridge Horse Railroad, which opened on June 13, 1859. The line beat a rival company by buying seco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Harvard Branch Railroad
The Harvard Branch Railroad was a short-lived branch from the Fitchburg Railroad to Harvard Square and Harvard University in Cambridge, Massachusetts. Part of the former right-of-way is now used by Museum Street. The company was incorporated April 24, 1849, and soon built a line long from just west of Somerville station on the Fitchburg Railroad (at Park Street) southwest to Harvard. On April 19, 1854 it was authorized to abandon the line, and did so in 1855. The Cambridge Railroad started running to Harvard from Boston in 1856 as a street railway A tram (called a streetcar or trolley in North America) is a rail vehicle that travels on tramway tracks on public urban streets; some include segments on segregated right-of-way.

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 ...

Horsebus
A horse-bus or horse-drawn omnibus was a large, enclosed, and sprung horse-drawn vehicle used for passenger transport before the introduction of motor vehicles. It was mainly used in the late 19th century in both the United States and Europe, and was one of the most common means of transportation in cities. In a typical arrangement, two wooden benches along the sides of the passenger cabin held several sitting passengers facing each other. The driver sat on a separate, front-facing bench, typically in an elevated position outside the passengers' enclosed cabin. In the main age of horse buses, many of them were double-decker buses. On the upper deck, which was uncovered, the longitudinal benches were arranged back to back. Similar, if smaller, vehicles were often maintained at country houses (and by some hotels and railway companies) to convey servants and luggage to and from the railway station. Especially popular around 1870–1900, these vehicles were known as a 'private omni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Harvard University is a private Ivy League research university in Cambridge, Massachusetts. Founded in 1636 as Harvard College and named for its first benefactor, the Puritan clergyman John Harvard, it is the oldest institution of higher learning in the United States and one of the most prestigious and highly ranked universities in the world. The university is composed of ten academic faculties plus Harvard Radcliffe Institute. The Faculty of Arts and Sciences offers study in a wide range of undergraduate and graduate academic disciplines, and other faculties offer only graduate degrees, including professional degrees.

Gas Explosion
A gas explosion is an explosion resulting from mixing a gas, typically from a gas leak, with air in the presence of an ignition source. In household accidents, the principal explosive gases are those used for heating or cooking purposes such as natural gas, methane, propane, butane. In industrial explosions many other gases, like hydrogen, as well as evaporated (gaseous) gasoline (American English)/petrol (British English) or ethanol play an important role. Industrial gas explosions can be prevented with the use of intrinsic safety barriers to prevent ignition. Lower and upper explosive limits Whether a mixture of air and gas is combustible depends on the air-to-fuel ratio. For each fuel, ignition occurs only within a certain range of concentration, known as the upper and lower flammability limits. For example, for methane and gasoline vapor, this range is 5-15% and 1.4-7.6% gas to air, respectively. An explosion can only occur when fuel concentration is within these limits. List ...

Compressed Natural Gas
Compressed natural gas (CNG) is a fuel gas mainly composed of methane (CH4), compressed to less than 1% of the volume it occupies at standard atmospheric pressure. It is stored and distributed in hard containers at a pressure of , usually in cylindrical or spherical shapes. CNG is used in traditional petrol/internal combustion engine vehicles that have been modified, or in vehicles specifically manufactured for CNG use: either alone (dedicated), with a segregated liquid fuel system to extend range (dual fuel), or in conjunction with another fuel ( bi-fuel). It can be used in place of petrol (gasoline), diesel fuel, and liquefied petroleum gas (LPG). CNG combustion produces fewer undesirable gases than the aforementioned fuels. In comparison to other fuels, natural gas poses less of a threat in the event of a spill, because it is lighter than air and disperses quickly when released. Biomethane – refined biogas from anaerobic digestion or landfills – can be used. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
