Transfer table
From Wikipedia, the free encyclopedia
A transfer table, also called a traverser (especially in the UK), is a piece of railroad equipment. It is similar in function to a turntable, though it cannot be used to turn equipment around. The table consists of a single length of track which can be moved from side to side, in a direction perpendicular to the track. There are often multiple tracks on one side of the table and a single track on the other.
They are often found in yards with locomotive maintenance facilities. The table allows a shed with multiple stalls for locomotives or cars to be served by a single track, without the need for a number of switches which could take up a much larger area. Traversers were also used at metropolitan terminus locations where space is at a premium - such as at Kew and St. Kilda railway stations in suburban Melbourne, Victoria, Australia; both these traversers worked only two tracks.
[edit] Combined turntable and traverser
In rare instances, the turning features of a turntable have been combined with the lateral motion features of a transfer table. Examples of such installations are in use in Asia.
An example of both pieces of equipment was in use through the 70's at the Collinwood Yards in Cleveland, OH
