Heritage railway
A heritage railway is a railway kept to carry living history rail traffic in order to re-create or preserve railway scenes of the past. Often heritage railways are old railway lines preserved in a state which depicts a certain period, or periods, in the history of railway systems.
Heritage line
Heritage railway lines contain historic rail infrastructure that has been substituted or made obsolete in modern railway transit systems. Historical installations, such as hand operated points, water cranes, and rail fastened with hand hammered rail spikes, are characteristic features of heritage lines. Apart from mere tourist railways, which carry mainly tourists and use only modern installations and vehicles, heritage lines' infrastructure naturally creates views and soundscapes of the past while operated.
Operation
Due to the lack of modern technology, or to a desire for historical accuracy, railway operations can be handled with traditional practices, such as the use of physical tokens. Use of heritage infrastructure and operations often calls for assigning roles based on historical occupations to the railway staff. Station masters and signalmen, sometimes wearing period-appropriate attire, can be seen on some heritage railways. Most heritage railways carry heritage rolling stock, but modern rail vehicles can be used to showcase railway scenes with historical line infrastructure.
