input question: Information: - A tram stop, tram station, streetcar stop, or light rail station is a place designated for a tram, streetcar, or light rail vehicle to stop so passengers can board or alight it. Generally, tram stops share most characteristics of bus stops, but because trams operate on rails, they often include railway platforms, especially if stepless entries are provided for accessibility. However, trams may also be used with bus stop type flags and with mid-street pavements as platforms, in street running mode. - On-street running or street running is the routing of a railroad track or tramway track running directly along public streets, without any separation. The rails are embedded in the roadway pavement, and the train shares the street directly with pedestrians and automobile traffic. Trains generally travel at reduced speed for safety reasons. - A tram (also known as tramcar; and in North America known as streetcar, trolley or trolley car) is a rail vehicle which runs on tracks along public urban streets, and also sometimes on a segregated right of way. The lines or networks operated by tramcars are called tramways. Tramways powered by electricity, the most common type historically, were once called electric street railways (mainly in the USA). However, trams were widely used in urban areas before the universal adoption of electrification; other methods of powering trams are listed below under "History". - An island platform ( also center platform , centre platform ) is a station layout arrangement where a single platform is positioned between two tracks within a railway station , tram stop or transitway interchange . Island platforms are popular on twin - track routes and can provide for services in both directions from a single platform requiring only one set of supporting services ( lifts , escalators , toilets , ticket offices , kiosks ) . They are also useful within larger stations where local and express services for the same direction of travel can be provided from opposite sides of the same platform thereby simplifying transfers between the two . An alternative arrangement is to position side platforms on either side of the tracks . - Accessibility refers to the design of products, devices, services, or environments for people who experience disabilities. The concept of accessible design and practice of accessible development ensures both "direct access" (i.e. unassisted) and "indirect access" meaning compatibility with a person's assistive technology (for example, computer screen readers). - A railway platform is a section of pathway, alongside rail tracks at a railway station, metro station or tram stop, at which passengers may board or alight from trains or trams. Almost all rail stations have some form of platform, with larger stations having multiple platforms. The term "platform" has also gained usage as a verb among some rail conductors, as in, "The first two cars will not platform at [station]". - Light rail, light rail transit (LRT) or fast tram is urban public transport using rolling stock similar to a tramway, but operating at a higher capacity, and often on an exclusive right-of-way. - A bus stop is a designated place where buses stop for passengers to board or alight from a bus. These are normally positioned on the highway and are distinct from off-highway facilities such as bus stations. The construction of bus stops tends to reflect the level of usage. Stops at busy locations may have shelters, seating, and possibly electronic passenger information systems; less busy stops may use a simple pole and flag to mark the location. Bus stops may be clustered together into transport hubs allowing interchange between routes from nearby stops and with other public transport modes. Given the paragraphs above, decide what entity has the relation 'subclass of' with 'railway platform'.???
