About the 421 Class
The 421 class are a class of mainline diesel locomotives built by Clyde Engineering, Granville for the New South Wales Government Railways in 1965-1966. The 421 Class featured the classic bulldog nose at one end, and featured a flat-cab at the other end.
The 421 class initially entered service on 22nd December 1965 when the NSWGR took delivery of 42101, the first unit of an order for ten locomotives, running on the Main South line before being transferred to Bathurst in 1970 to operate services on the Main Western line between Lithgow and Broken Hill including the new Indian Pacific service. However due to their poor ride quality, they were returned to the Main South. In 1982, locomotives 42102, 42103, 42104, 42106 and 42109 were seen being used on services in Victoria on a regular basis. They were later banned in Victoria by May 1983.
Some 21 years after begin their service, all 10 were withdrawn from service in December 1986 and January 1987 and put in storage at Junee Locomotive Depot, even though some had only recently been overhauled. In 1990 most of them were offered for sale. Four locomotives were purchased by Northern Rivers Railroad and continued to operate but in March 2002, all were included in the sale to Interail to QR National who regularly operated them as far south as Melbourne. Three were withdrawn and placed in storage in January 2013 with one remaining in service.
By the end of 2014, only 1 is in service (42103), 2 are preserved (42101,42102), 4 are stored (42105/06/07/09) and 3 have been scrapped (42104/08/10)
In August 2015, Auscision released the 421 Class locomotive which includes a 21 Pin socket for easily fitting a DCC decoder plus a speaker enclosure that suits a 20x40mm speaker. There are micro switches under the model for turning lights on/off in DC. In DCC all lights operate directional.
A second release of the model was done in May 2017 and was the same as the first release.
For this installation we recommend the ESU LokSound 5 (Sound) with our Custom Sound Project for the 421 Class or the LokPilot V4.0 (No Sound) for those not wishing sound. We offer several options of DCC installations for this model to suit all budgets and can supply the decoders only for the DIY installers.
We have tweaked the motor control of the ESU decoder to provide super slow smooth speed which is perfect for shunting operations allowing the loco to move ever so slowly towards its rolling stock. Also, for those wanting the locomotive to move off slowly and build up speed like the prototype. You will be impressed with the smooth slow speed motor control.
We offer a light modification for this 421 Class Model to separate the lights for a more prototypical operation.
We can separate the headlights, white markers and red marker lights for a more prototypical operation . Each pair of front and rear marker lights can be controlled individually so when the locomotive is standing in a siding or shunting it can have both front and rear red markers on at the same time as per NSWGR practice. Also you can have no rear markers on when pulling a load or simply just have the front white markers switched on. The front and rear headlights operate directionally and have a Low Beam/High Beam function.
You can also still operate all the lights directional as the way the model was delivered.
For a Standard Light Modification we can separate the lights as follows:
4) Front White Markers - on/off with 1 function button
5) Front Red Markers - on/off with 1 function button
6) Rear White Markers - on/off with 1 function button
7) Rear Red Markers - on/off with 1 function button
Our Custom Sound Project now includes these fantastic features:
Full Throttle – Drive Hold
This feature allows you to simulate a loaded or empty train by pressing the F1 function button. When the button is pressed, the motor will remain at a constant speed, while the sound can be controlled independently by adjusting the speed on the throttle. This exciting, new feature gives the operator the ability to have the train crawl in notch 8 or coast at 100 km/h. Release the Drive Hold function button and you simply go back to throttle-controlled speed and motion. Available only from DCC Solutions, our Drive Hold will stop your loco when you reduce the speed to zero even while the function is still active. Your ESU factory fitted or downloadable sound will not stop your loco at speed step 0 with the drive hold on.
Coasting on Demand
This feature allows you to enter coasting mode whenever you want with a press of a button. Often when coming to a stop, the throttle of a real locomotive is put into Idle and the locomotive coasts to a stop. Another situation that occurs is that once a train is up to speed when operating over the
NSW's countryside, the driver can coast to maintain a certain speed. By pressing the coast function button, the sound drops into coasting and remains there. Using the throttle speed control, you can now speed up or slow down the train with the sound remaining in coasting mode.
Press the function button to exit coasting and the sound will exit and return to whatever speed is set when exiting.
Press the Brake Function button and your locomotive will come to a stop at a much shorter distance than if you were to bring it to a stop by reducing the throttle speed. Release the brake and your locomotive will move off again or choose to have it remain stationary when the brake is released.
Working Dynamic Brake
Apply the Dynamic Brakes and the Prime Mover will wind down to idle while the Dynamic Fans engage to assist with cooling. Reduce the throttle and the decoder's dynamic braking logic will reduce your speed faster than normal. Disengage Dynamic Braking and the primer mover will returned to it's notched speed and the fans will turn off.
Random Start-up Sequences with Move Off and Stopping Sounds
Now with random start-up sequences including hot or cold engine starts your start up and shut down will not always sound the same.
As your locomotive begins to move off you will hear the sounds of brakes releasing with random speed activated wheel squeal, rail noises and other sounds. Some of these sounds are random or speed sensitive that will turn on/off automatically depending on your take off speed. When the locomotive comes to a stop you will hear the squeal of the brakes, air releases and then the compressor will cut in automatically to fill the reservoirs with air until full and will cut out.
