A Redhen is a type of diesel railcar
Railcar
A railcar, in British English and Australian English, is a self-propelled railway vehicle designed to transport passengers. The term "railcar" is usually used in reference to a train consisting of a single coach , with a driver's cab at one or both ends. Some railways, e.g., the Great Western...

 withdrew the last Redhens from regular service in October 1996, following delivery of a new fleet of 3000-class diesel-electric railcars. A number of Redhens have been preserved and are now operated by heritage and tourist railways in Australia.

Fleet details

The Redhens comprised two designs:-
  • 300-class had a driving cab at one end of each railcar. These needed to run as a minimum of 2-car trains.
  • 400-class had driving cabs at both ends, and could be used as a single car when needed, or in multiple

     with other railcars to make up longer trains.


In addition, there were a number of unpowered trailer cars, designated 820-class or 860-class. These had been modified from steam-era suburban carriages and were used with the Redhens between 1955 and 1987.

Construction

The Redhens were built in three batches. The overall design of the railcars was very similar, but there were differences in detail between the batches. Several railcars in the 300 class were re-numbered later in life, taking on the numbers of written-off or modified units.

The exterior of the units was always painted red, with variations in the colour of roofs and bogies over the years. The interior design and layout remained largely unchanged throughout their life. Some 300-class units were modified to provide guard’s accommodation or space for bikes when the 860-class trailers had been withdrawn in 1987. This slightly reduced the seating capacity

Deployment

When first introduced, all the 300-class Redhens were made up into 3-car consists, comprising an 820 or 860-class trailer sandwiched between two powered 300-class railcars. In peak hours, two sets were coupled together to make 6-car trains. On rare occasions, at times of heavy traffic demand, trains of Redhens could be up to 9 cars long.

Instead of building trailer cars to work with the 300-class cars, SAR chose to convert existing rolling stock instead. Initially, the five 800-class trailers and nine 850-class trailers were converted, becoming the 860-class trailers. Ironically, these cars were built in the mid 1940's as part of a plan to electrify Adelaide's suburban railways. After the 800/850-class trailers were converted, thirteen end loading suburban baggage cars were converted, becoming the 820-class trailers.

In the early 1970s SAR set aside funds to build eight 300-class cars and four trailer cars to work with them. The trailer cars would have been the 120-class. The cars were never built and the money set aside for their construction was ultimately used on the construction of the 2000/2100-class railcars

 new 2000-class railcars in 1980, two 300-class Redhens and a 860-class trailer were chosen for an experimental rebuild at the Regency Park workshops. Nos. 300, 337 and trailer 862 were modified in 1983 with new interiors, elevated cabs (similar to the 2000-class) and an exterior appearance like a hybrid between a traditional Redhen and a 2000-class Jumbo.

The rebuilt cars were re-numbered 2301, 2302 and 2501 and nicknamed Super Chooks (a chook is a chicken in Australian vernacular). The exercise was not successful and no more Redhens were modified. The Super Chooks saw only limited passenger service and often 2301-2302 was sandwiched in between 2 400 class redhen railcars before they were withdrawn in 1992. Following the collapse of the Lions Club of Yorke Peninsula Rail Inc, they are for sale.

All thirteen of the 820-class trailers were retired by December 1976 (these were wooden-bodied coaches and most had originally been built between 1912 and 1918). The corresponding 300-class Redhens were then coupled to a 400-class railcar to form 2-car trains (designated 300/400-class).

In 1987, the steel-bodied 860-class trailers were withdrawn and all the 300-class Redhens were reconfigured as 2-car trains, usually consecutively numbered pairs.

By the mid-1980s the Redhens ranged from 15 to 30 years in age. Whilst they had been faster and more comfortable than the steam trains they replaced in the 1950s, the design of the Redhens compared unfavourably with contemporary standards of passenger rolling stock. For example, they have neither heating nor air conditioning, which made them unpopular with commuters in mid-summer and mid-winter. They also have manually operated sliding doors, which were perceived as a safety hazard (particularly since de facto air conditioning was achieved during hot summer weather by passengers leaving the Redhens’ sliding doors wide open between stations).

s, which were intended to replace the Redhens. As more 3000 and 3100-class railcars were delivered through the early 1990s, the Redhens began to be withdrawn and were gradually restricted to operating only during weekday peak hours. This was especially the case when the STA moved towards driver-only-operation (DOO) of the rail system in the early 1990s. The manual sliding doors made Redhens unsuitable for DOO and guards had to be retained to supervise passenger boarding and alighting.

Following the final delivery of 3100-class railcars, TransAdelaide operated their last Redhens in public service in October 1996 which were railcars 428 and 436.

Preservation

Whilst in service the Redhens were mechanically robust and reasonably reliable; they were attractive options for use on heritage and tourist railways after retirement. However, their age, and the increasing service time since overhaul, has affected their reliability in preservation. Some continue to operate on broad gauge
