11 Operating Control Principles
11.1 Rail Systems
This rail axle position automatically manages the rail functions for all rail-mounted operations. When
operated, the blade controls are reassigned to operate the rail drive, rail brakes and rail axle deploy
functions. It also activates the rail navigation lights and speed restriction system. The dozer blade
shims and blade trolley lock system are all manually applied. Gauging interlocks are also maintained
by the ram shims.
11.2 Blade UP-DOWN/Ripper Control Lever
Normally this operates the blade up/dn ram or ripper up/dn ram, but in rail mode this controls the rail
axle up down and rail travel depending on which function is selected by the operator.
When the axle changeover is operated, this lever then raises and lowers the rear rail gear.
When the drive changeover is operated, and the secondary drive acknowledge button pressed, this
lever then drives the rear rail gear forwards or backwards.
Note: Rail function will only operate if the track drive lever, cab exit lock is down to isolate the crawler
travel controls.
11.3 Rail Axle Deploy/Rail Drive Change-Over
This changes between rear rail gear for raising and lowering the rear wheels and rail travel. Note that
the rail travel interlock is always active when operating the rail axle ram. The light in the switch will
illuminate when the rail gear is fully deployed for travel.
11.4 Rail Axle Deploy
To deploy the rear rail axle, ensure that the rail master switch is on and then press and hold the rail
axle deploy switch position and operate the blade raise lower lever to raise and lower the rail drive
axle. The light in the switch will illuminate when the rail axle is fully deployed for travel.
11.5 Bogie Axle Deploy
To deploy the front rail bogie, ensure that the rail master switch is on and operate the blade raise
lower lever to raise and lower the blade as normal.
11.6 Blade Rams Lock
Once the blade ram locks have been inserted the locks will ensure that W6A gauge requirements are
maintained. This may require the blade rams to be moved to find the position that the lock engages.
The blade functions should not be actuated until the ram shims are removed again for off tracking.

Issue 1 Page 16 of 34 Initial Issue 19 December 2017 Engineering Manager
11.7 Crawler Tracks Interlock
The machine will only actuate the rear rail axle ram and travel on rail with the Crawler Track Cab exit
lever down. This interlock prevents the machine spinning the tracks whilst operating rail functions.

Interlock

Issue 1 Page 17 of 34 Initial Issue 19 December 2017 Engineering Manager
11.8 Rail Drive Acknowledge Interlock
The machine will only travel on rail with the drive acknowledge switch pressed. This interlock prevents
the machine from travelling should the operator become incapacitated. The light in the switch will
illuminate when the switch is activated and the rail systems is correctly set for travel.
Figure 3 - Rail Drive Acknowledge Interlock
11.9 Rail Travel
To travel on rail select the rail drive switch and the Drive Acknowledge switch then has to be pressed
and held down. Simultaneously push and hold the travel lever into the forward position to initiate
forward travel or pull it back for reverse travel.
11.10 Low Speed Selector
To operate the low gear selector the gear switch has to be pressed and held in. Simultaneously push
and hold the travel lever into the forward position to initiate forward travel or pull it back for reverse
travel.
Note: In rail mode, the machine will have a top speed of 5mph in normal mode and 2mph in low gear
mode.

12 On / Off Tracking
ON/OFF TRACK THE MACHINE ONLY AT AN APPROVED ACCESS POINT.
NOTE –AN APPROVED ACCESS POINT IS ONE OF THE FOLLOWING:
Level crossing.
Yard where surface is level with the rail top.
Proprietary approved track access system with rail shields.
Consolidated ballast to at least the underside of the rail head with rail shields.
THE FOLLOWING HAZARDS SHOULD ALSO BE ADDRESSED:
Cant - not to exceed 150mm.
Gradient - not to exceed 1:25.
Curve radius - not to exceed 60m.
Ballast shoulder - must be low.
Deep cess / soft cess must not be travelled across.
Drainage routes, troughing routes and other services/cables must not be approached.
OHLE, 3rd rail must be where gap exists on both sides.
Power cables.
Care should be taken when on/off tracking with tracked excavators not to damage the railhead,
suitable rail shields should be used.
When on tracking, the rear rail wheels should be aligned to the rail precisely and the bogie
wheels aligned to within 250mm of the rail head. This may take several manoeuvres. The
bogie can then be accurately aligned utilising the tilt and angle blade ram functions. Only once
alignment has been achieved, should the rail gear be deployed.
Do not attempt to manoeuvre the dozer with the crawler tracks, when the rail gear is semi/fully
deployed.
[WARNING] When on tracking, care must be taken when lowering the bogie onto the rail head to
ensure all four wheels of the trolley contact the rail before the weight of the dozer is exerted onto the
trolley. If the blade is not angled perpendicular with the rail within the float tolerance of the trolley at all
times de-rail may occur and/or severe damage to the bogie may result.

Issue 1 Page 19 of 34 Initial Issue 19 December 2017 Engineering Manager
13 Suggested On / Off Tracking Area Requirements
Figure 4 - On / Off Tracking Area
1. A Rail-Ability Universal Track Access System is recommended for on and off tracking a bull
dozer.
2. Drive forwards and align the machine parallel to the track.
3. Reverse the machine at 30° to the track from the parallel position to traverse the track/UTAS.
4. Fully straddle the track with the Crawlers and align the front bogie and rear rail axle with the
track/UTAS.
5. Deploy the rear rail axle to only just lift the rear of the machine slightly clear of the
Track/UTAS.
6. Utilise the blade angle function on the machine to fine align the front rail bogie with the track.
7. Deploy the rear rail axle fully then deploy the front rail bogie until all of the ram shims can be
installed.
8. Insert all four ram shims and lock in place then activate the crawler joystick cab exit interlock.
9. Travel on rail is only possible when activating the additional momentary rocker switch on the
cab console with left hand.

Issue 1 Page 20 of 34 Initial Issue 19 December 2017 Engineering Manager
14 Installation of Ram Strut for Travelling On Track
[WARNING] The ram struts must always be installed when the dozer is on rail. These ensure the
dozer blade does not settle and hence keeps the dozer within w6 gauge requirements. Failure to fit
these may result in striking line side equipment and/or structures.
[WARNING] Ensure that the blade is angled and tilted to its maximum extent and that an equal
amount of blade over hang is achieved over the sides of the trolley. This ensures the dozer remains
within w6 gauge requirements. Failure to ensure that this is done may result in striking line side
equipment and/or structures.
When the dozer is on track release the struts from the anti-loose couplings on the back of the blade
and remove the pins.
Figure 5 - Ram Strut
Operate the blade lever to deploy the blade and extend the rams just enough to slide the struts over
the ram rod. Then install the retaining pins. Gradually lower the dozer onto the struts, by operating
the blade lever to raise the blade.
