About the T Class

The T class are a class of diesel locomotives built by Clyde Engineering, Granville NSW for the Victorian Railways between 1955 and 1968

In July 1954 the Victorian Railways placed an order with Clyde Engineering for 25 (later extended to 27) diesel electric Electro-Motive Diesel G8 locomotives to partially dieselise country branch lines.

In June 1959 the first of an additional ten entered service. Although mechanically similar to the first batch they differed by having a cab raised above the hood line. A further ten entered service from December 1961.In September 1965 the first of an order for another 32 was delivered. These differed by having a lower nose. A final order for 19 was delivered from April 1967. The last five were built with an extra 10 tonnes (9.8 long tons; 11 short tons) of ballast weight for improved adhesion and low speed controls for use as shunting locomotives in Melbourne. These were reclassified as the H class shortly after being delivered.

Although ordered as branch line locomotives, as branch lines began to close they were often used on main line services.

In 1984/85 Martin & King, Somerton rebuilt 13 flat tops as P class locomotives. This involved a new cab and car body, replacing the EMD 8-567C engine with an EMD 8-645E, replacement of the main generator and traction motors, and provision of a separate head end power generator.

Many were withdrawn in the late 1980s with the arrival of the G class locomotives. In October 1992 six low nose locomotives were sold to Australian National. Others were sold to Chicago Freight Car Leasing Australia, El Zorro, Great Northern Rail Services, SCT Logistics, Southern Shorthaul Railroad, and West Coast Railway. A number of T class still remain in service with some being preserved or stored with the remainder scrapped. Those remaining with V/Line Freight were included in the sale to Freight Australia and in 2000 some stored examples were reactivated and fitted with standard gauge bogies to haul grain services in southern New South Wales. These later were passed onto Pacific National.

The class can be divided into three main styles by appearance:

  • Flat Tops: T320-T346 (1st order). Based on Electro-Motive Diesel G8 locomotive design, they had a nose, cab roof and rear body at the same height
  • High Nose: T347-T356 and T357-T366 (2nd and 3rd orders). They differed from the flat tops by having a lower nose and rear body but were mechanically similar. The 3rd order had an altered radiator design.
  • Low Nose: T367-T386, T387-T396, T397-T406 and T407 to T417 (4th-7th orders). The 4th order introduced a new low nose that provided greater driver visibility, and a more modern generator. The 6th order introduced the newer EMD 645E engine, replacing the older EMD 567.
  • The H class diesel-electric locomotive were part of the 7th T class order numbered T413-T417 at delivery but renumbered shortly after delivery.
  • T413: Built in 1956 for the narrow gauge Fyansford Cement Works Railway, Geelong as D1, it was sold to Victorian Railways, renumbered T413 and had its footplates replaced with similar ones to those already on their pre-existing Ts. Fitted with dynamic brakes
  • T414: Built in November 1956 as DE02 for BHP, was used at their Iron Knob and Whyalla Steelworks. Was not included in Morrison-Knudsen rebuild program like the rest of the class. In 2006 it was sold to SCT Logistics and rebuilt with a cab similar to those on the 4th/5th generation T Class locomotives and was renumbered T414.

DCC with Sound and Lighting Modifications

In 2006, Powerline Models released the "T" Class locomotive which included a poor quality DC/DCC decoder that required the user to open the locomotive to access the decoder and slide a switch for it to operate in either DC or DCC. In DC/DCC all lights operate directional.

For this installation we recommend the ESU LokSound V5 (Sound) with our Custom Sound Project for the T Class or the LokPilot V4.0 (No Sound) for those not wishing sound. We can supply the decoders only for the DIY installers.

Our Custom Sound Project is NOT the basic sound file being offered by Powerline..... It's Better!

And it does contain prototypical recorded sounds.

Here at DCC Solutions we offer a light modification for the Powerline T Class to separate the headlights, white markers and red marker lights to offer you more lighting options when running your T Class. Each pair of front and rear marker lights can be controlled individually as well as the front and rear headlights. Included is a High Beam Headlight function.

The DCC Solutions VIC T Class Custom Sound Project

is packed with sounds and features not found on other sound decoders especially factory fitted sound.

Factory Fitted Sound only offers you the very basic sound for your model

So why not get fully featured sound from DCC Solutions

Our Custom VIC T Class Sound Project now includes these new 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 sound will not stop your loco at speed step 0 or by trying to use the brake with the drive hold on. So watch out you don't crash your loco.

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

rolling 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.

Working Brake

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 (T413 Only)

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.

Coupling and Release with Shunting Mode

Activate coupling or release and your loco will automatically reduce its speed to allow for a more realistic coupling or release operation. Once the operation is completed your loco will continue to run at slow speed for a few more seconds before returning to the speed set on your throttle.

Manual Notching

For those who really want to drive their train and manually control the notching rather than letting the decoder do it.

Remastered Horn Sounds

A new remastered WABCo Pneuphonic A/B Series playable and short blast horn.

A new remastered RVB Hurricane 3 Chime Series playable and short blast horn.

Random Sounds

While the factory fitted sound will only offer you 1-2 random sound, DCC Solutions will have up to 12 random sounds that will play when either the loco is stopping or moving as we have been doing for years in all our Custom Sound Projects.

And includes all these great features to make your Victorian T Class drive and sound impressive.

  • EMD 8-567CR Prime Mover Sound (T320-T398)
  • EMD 8-645E Prime Mover Sound (T399-T413)

  • WABCo Pneuphonic A/B Long and Short Horn (T320-346) 1st Series
  • RVB Hurricane 3 Chime Long and Short Horn (T347-T412)
  • Air and Brake Release Sounds when loco moves off and stops including Brake Squeal
  • When the loco stops after braking the compressor cuts in to fill the reservoir and will turn off when the tanks are full.
  • Speed sensitive Wheel Squeal and Rail Noise when the loco moves off
  • Full Throttle Drive Hold - Lock the loco speed and control the sound independently to simulate a heavy loaded or empty train
  • Coasting On Demand
  • Working Brake to bring your locomotive to a stop even when Full Throttle Drive Hold is active unlike other ESU sound files.
