List Of Steepest Gradients On Adhesion Railways
The inclusion of steep gradients on railways avoids the expensive engineering works required to produce more gentle gradients. However the maximum feasible gradient is limited by how much of a load the locomotive(s) can haul upwards. Braking when travelling downhill is also a limiting factor. There have been various solutions to hauling rail mounted vehicles up or down inclines. These include simple rail adhesion, rack railways and cable inclines (including rail mounted water tanks to carry barges). To help with braking on the descent, a non-load-bearing "brake rail" located between the running rails can be used, similar to the rail used in the Fell system, e.g. by the Snaefell Mountain Railway on the Isle of Man. Tramways and light railways often have steeper gradients than heavier railways. This is because all wheels are usually connected to engine power in order to give better acceleration. Grades of 5% are not uncommon on them. Metros and pure commuter railways often also al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grade (slope)
The grade (also called slope, incline, gradient, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the slope, where zero indicates horizontality. A larger number indicates higher or steeper degree of "tilt". Often slope is calculated as a ratio of "rise" to "run", or as a fraction ("rise over run") in which ''run'' is the horizontal distance (not the distance along the slope) and ''rise'' is the vertical distance. Slopes of existing physical features such as canyons and hillsides, stream and river banks and beds are often described as grades, but typically grades are used for human-made surfaces such as roads, landscape grading, roof pitches, railroads, aqueducts, and pedestrian or bicycle routes. The grade may refer to the longitudinal slope or the perpendicular cross slope. Nomenclature There are several ways to express slope: # as an ''angle'' of i ...

J Church
The J Church is a hybrid light rail/ streetcar line of the Muni Metro system in San Francisco, California. The line runs between Embarcadero station and Balboa Park station through Noe Valley. Opened on August 11, 1917, it is the oldest and has the lowest ridership of all of the Muni Metro lines. Route description The inbound terminal is at Embarcadero station. The line runs west through the Market Street subway to a portal on Duboce Avenue, before turning onto Church Street. The line continues south on Church Street to 18th Street. Between 18th and 20th Street, the line cuts through Dolores Park in a private right-of-way featuring a 9% grade, the steepest section of the Muni Metro system.

Brown Line (Pittsburgh)
The Brown Line (formerly route 52) was a branch of the Pittsburgh Light Rail system that ran from South Hills Junction over Mount Washington and across the Monongahela River to downtown Pittsburgh, terminating at Gateway Center. It included the steepest grade of any section of the Pittsburgh light rail system, of approximately 10 percent. History The 52 Allentown route was created in 1984 by renaming what was then the ''49 Arlington-Warrington'', itself created in 1971 by combining portions of the ''48 Arlington'' and ''49 Beltzhoover'' lines. In April 2010 the 52 Allentown was rebranded the "Brown Line" by the Port Authority. Prior to being discontinued, Brown Line service was severely reduced, operating only during Monday to Friday rush hours, with bus route 44 substitute providing service at other times. The Port Authority considered ending all Brown Line service, but this would have provided only limited savings unless the tracks and overhead wires were also decommis ...
