Massachusetts Route 128
Route 128, known as the Yankee Division Highway, is an expressway in the U.S. state of Massachusetts maintained by the Highway Division of the Massachusetts Department of Transportation (MassDOT). Spanning , it is the inner one of two beltways around Boston (the other being Interstate 495 -495. The route's current southern terminus is at the junction of I-95 and I-93 in Canton, and it is concurrent with I-95 around Boston for before it leaves the interstate and continues on its own in a northeasterly direction towards Cape Ann. The northern terminus lies in Gloucester a few hundred feet from the Atlantic Ocean. All but the northernmost are a freeway, with the remainder being an expressway.

Infill Station
An infill station (sometimes in-fill station) is a train station built on an existing passenger rail, rapid transit, or light rail line to address demand in a location between existing stations. Such stations take advantage of existing train service and encourage new riders by providing a more convenient location. Many older transit systems have widely spaced stations and can benefit from infill stations. In some cases, new infill stations are built at sites where a station had once existed many years ago, for example the station on the Chicago 'L''s Green Line. Examples The Americas Canada *Montreal ** Griffintown–Bernard-Landry station, 2027 *Ottawa ** Corso Italia station, 2025 ** Walkley station, 2025 *Toronto ** North York Centre station, 1987 *Vancouver ** Lake City Way station, 2003 ** Capstan station, 2024 Chile *Santiago ** San José de la Estrella metro station, 2009 United States * Atlanta ** Peachtree Center station, 1982 * Phoenix ** 50th Street/Washingto ...

Boston Elevated Railway
The Boston Elevated Railway (BERy) was a Tram, streetcar and rapid transit railroad operated on, above, and below, the streets of Boston, Massachusetts and surrounding communities. Founded in 1894, it eventually acquired the West End Street Railway via lease and merger to become the city's primary mass transit provider. Its modern successor is the state-run Massachusetts Bay Transportation Authority (MBTA), which continues to operate in part on infrastructure developed by BERy and its predecessors. History Originally intended to build a short electric Light rail, trolley line to Brookline, the West End Street Railway was organized in 1887. By the next year it had consolidated ownership of a number of Horsecar, horse-drawn streetcar lines, composing a fleet of 7,816 horses and 1,480 rail vehicles. As the system grew, a switch to underground pulled-cable propulsion (modeled after the San Francisco cable car system) was contemplated. After visiting Frank J. Sprague, Frank Spr ...

MBTA Accessibility
The Massachusetts Bay Transportation Authority (MBTA) system is mostly but not fully accessible. Like most American mass transit systems, much of the MBTA subway and MBTA Commuter Rail, commuter rail were built before wheelchair access became a requirement under the Americans with Disabilities Act of 1990. The MBTA has renovated most stations to be compliant with the ADA, and all stations built since 1990 are accessible. The MBTA also has a paratransit program, The Ride (MBTA), The Ride, which provides accessible vehicles to transport passengers who cannot use the fixed-route system. Much of the MBTA subway system is accessible: all Orange Line (MBTA), Orange and Red Line (MBTA), Red Line stations, and all but one Blue Line (MBTA), Blue Line station, are accessible. Most of the underground portion of the Green Line (MBTA), Green Line is accessible, though only some surface stops are; all but one stop on the Mattapan Line are accessible. As of March 2025, about 84% of the MBTA Comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automatic Train Control
Automatic train control (ATC) is a general class of train protection systems for railways that involves a speed control mechanism in response to external inputs. For example, a system could effect an emergency brake application if the driver does not react to a signal at danger. ATC systems tend to integrate various cab signalling technologies and they use more granular deceleration patterns in lieu of the rigid stops encountered with the older automatic train stop (ATS) technology. ATC can also be used with automatic train operation (ATO) and is usually considered to be the safety-critical part of a railway system. There have been numerous different safety systems referred to as "automatic train control" over time. The first experimental apparatus was installed on the Henley branch line in January 1906 by the Great Western Railway, although it would now be referred to as an automatic warning system (AWS) because the driver retained full command of braking. The term is especi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grade Separation
In civil engineering (more specifically highway engineering), grade separation is a method of aligning a junction of two or more surface transport axes at different heights ( grades) so that they will not disrupt the traffic flow on other transit routes when they cross each other. The composition of such transport axes does not have to be uniform; it can consist of a mixture of roads, footpaths, railways, canals, or airport runways. Bridges (or overpasses, also called flyovers), tunnels (or underpasses), or a combination of both can be built at a junction to achieve the needed grade separation. In North America, a grade-separated junction may be referred to as a ''grade separation'' or as an '' interchange'' – in contrast with an ''intersection'', '' at-grade'', a '' diamond crossing'' or a ''level crossing'', which are not grade-separated. Effects Advantages Roads with grade separation generally allow traffic to move freely, with fewer interruptions, and at higher overall ...
