Redhen

The Redhen Railcars were diesel-powered self-propelled railcars built by the South Australian Railways' (SAR) Islington Workshops. They were built between 1955 and 1971. 
== History ==
Between the late 1950's - early 1990's, the Redhen Railcars represented the backbone of South Australia's metropolitan rail system as the first modern motive power to replace steam traction on suburban passenger trains from Adelaide. 
By the end of their production in 1971, a total of 111 examples had been built, the latest of which were to take over from 1920's-vintage diesel railcars. 
In regular service, the Redhens lasted until December 1996, following the delivery of the more advanced 3000 / 3100 Class Railcars from Clyde Engineering. Fortunately, no less than 34 of the Redhens are currently in preservation, with some in operation on a number of heritage and tourist lines. 
== Fleet Details ==
The Redhen fleet comprises of two separate designs: 
* The 300 Class (#300-373), with a drivers' cab at one end only, necessitating operation in two-car formations. 
* The 400 Class (#400-436), with a drivers' cab at both ends, allowing single- or multiple-car operation for longer trains. 
A number of non-powered trailer cars of Class 820 and 860 were also produced; modified from suburban carriages of the steam era, they were once commonly in use with the Redhens between 1955-1987.
