MTMV, Fouling, ITD Flashcards
Rule 917 Individual Train Detection
Individual Train Detection (ITD) is the minimum qualification required to move and work on the rail corridor unsupervised. If you do not hold a Licence to Operate you must arrange to be accompanied by a qualified person.
ITD is a method of protection to be used for occupancy of main lines, crossing loop and all lines within interlock areas
ITD can be used for:
Moving on foot (inspections, investigations, site familiarisations);
Making minor corrections which will not interfere with the safe running of trains; and
When crossing the line at a maintenance crossing.
MTMV definition
MTMVs can be several kinds of heavy machinery fitted to work on the track.
Some of the vehicles are fitted with devices for being set off track.
MTMV’s may be operated singly or as a group.
When travelling on rail beyond the PWA,
MTMV’s running as a group must be coupled
together and be scheduled as a train.
When berthed/stabled or working within station limits or in a siding, the operator in charge of the MTMV(s) must ensure all practicable steps are taken to protect the machine(s) from collisions, including, but not limited to
Setting a diverging route;
Erecting a Danger Stop Disc / light and derailing block; and
Blocking (where available).
Every MTMV that is travelling will have a
three-digit ID, similar to a train number, i.e. BV2
The first letter relates to the line it is travelling on.
The second letter relates to whether the MTMV will activate track circuits or not.
The third number relates to direction up or down.
MTMV’s Travelling as “V”
MTMV with axle loads 10t and over with 4 or more axles may be relied upon to activate track circuits so will:
Be protected by track circuits/axle counters and detected on signal panels; and
Operate level crossing alarms
MTMV’s Travelling as “R”
MTMV with axle loads under 10t and or less than 4 axles:
Will not be protected by track circuits in Automatic Signalling areas;
May not activate level crossing alarms; and
May not be detected on signal panels.
R918 Foul Time Definition:
Foul Time is a method of using time and distance to create a time and distance buffer to allow an occupation on track when signals are not available to apply blocking.
The termination/clearance time must include a minimum safety buffer of 15 or 30 minutes before the anticipated arrival time of the next train(s).
Foul Time can be used for:
Occupancy of track on foot
Maintenance with light tools/ladders
HRV and Trolley movements on the
Midland Line
R918 Foul Time Enquiry
Identity;
State “Foul Time” required;
On tracking location (at location);
In Multi Line Areas, state lines being occupied or obstructed;
Occupation area including off tracking location;
Time required for work; and
Reason for requesting Foul Time.
R918 Foul Time pre checks
Ensure that the proposed occupancy will not conflict with rail movements (trains, Hi-Rail Vehicles, etc);
Confirm the location of conflicting rail movements;
Confirm the last train clear of on tracking location; and
Record the details on the graph.
R918 Foul Time authorization
Addressee
‘At’ location
Commencement time and Clearance time
In multi-line area state lines being occupied or obstructed
Proceed / Work at / Work between Locations
Last train clear
Foul time granted and safety buffer applied
Safety Buffers for 60 mins or greater
A safety buffer of 30 minutes between the clearance time and the anticipated arrival time of the train at the occupation area must be provided.
Safety Buffers for less than 60 mins
A safety buffer of 15 minutes between the clearance time and the anticipated arrival time of the train at the occupation area must be provided.
Grease Truck track occupation: (2)
When a track occupancy request is received for a Grease Truck, the authorisation must only to apply to sections of track that are completely clear of rail movements.
Grease Trucks cannot be authorised to follow trains or HRV’s as they are required to travel at 50km/h around curves.
