They are fitted with class EE (Double Shelf) couplers with overrun and underrun protection.
Wagons feature a brake air pipe, an ICC cable, and a dummy coupling.

Train ECP

Wagons have an ECP braking system allowing the driver to control all brakes simultaneously.
The system includes an ECP manifold and CCID (Car Control and ID Device).
ECP power is provided via the ICC cable (train line) and operates a 230v.
Disconnect the loco or switch off train line power before connecting the ICC cable.

Handbrake

The wagon has a manual handbrake with an electronic sensor that transmits handbrake status to the driver's fire screen via the CCID.
The SAR driver must review the ECP fire screen's event log for handbrake status before using a train on the main line.

Brake Requirements

Defective automatic brakes must be repaired; if not possible, the wagon may continue with authorized repairs.
Discharged wagons need to be moved to a maintenance facility after completion of delivery.
Handbrakes are applied to rakes of wagons with a ratio of 3 handbrakes for 1-30 wagons, and 10% for 31 wagons and over.
The driver must verify the handbrake status on the event log in the fire screen.

Piston Travel Indicator

The indicator visually confirms brake application or release, visible through the bogie frame or from the top.
The brake blocks still touch the wheel even when the brakes are released.
Check other indicators, such as the travel indicator and handbrake chain, as the blocks may touch the wheel.
The handbrake chain is loose when the handbrake is not applied.

Retainer Valve

The brake manifold/distributor has a prominent Retainer Valve that must remain in the vertical position.
It must not be confused with the Brake System Cut Out Cock fitted to the rear of the manifold/distributor.

Brake Isolation

In case of brake damage or defects, isolation allows wagon movement.

Turn the cut-out cock to the closed position.
Pull the release valve rod and release it after hearing air exhausting.
Check the piston travel indicator to confirm brake release.

Empty/Load Sensor Arm

The sensor arm mounted on the bogie provides information to the brakes about wagon load status.
The arm drops with brake application, indicating the driver has applied the train brakes.
A small air reservoir near the brake manifold is associated with the sensor arm.

Hazard Placard Holders and UN Numbers

Wagons have four hazard placard holders with one on each side and one at each end.
They display the UN Number for molten sulfur in English.

Defect Card Holders

The wagons are fitted with two defect card holders, one on each side.

Tank Top Fittings

Tanks are loaded through a manway on the top of the wagon.

Tank Bottom Fittings

There are five pipe connections below the wagon, including two for connecting steam lines for reheating the product.
The largest pipe is the bottom outlet valve for discharging the product.
Two additional valves are included for heating the outlet valve if blocked with solidified product.

Wagon Examination

All necessary pre-departure checks should be performed before releasing a train onto SAR infrastructure.
Consult the Driver Operations Handbook (SAR-005005-100100-33-002) for details on wheel requirements.
The examination includes checking for signs of wear, cracks, air leaks, open/closed pipes, and hanging non-utilized pipes on the dummy coupling.
Check for flats, cavities, scaling, flange height, and rollover on wheels.
Displaced, broken, or cranked springs must be detached.
Coil bound springs may indicate overloading.
Empty wagons can travel with a broken inner spring.
Verify handbrakes are fully off and check their operation.
Ensure all manways are closed with safety chains in place.
The examination must include checks for product spills, leaks, and reporting of incidents.

Departure Roll-by Inspection

Conduct the pre-departure and roll-by inspection form.
Look for signs of smoke from bearings, glowing metal, squealing, and grinding noises.
Smell for hot metal and hot cooking fat.
Feel for extreme heat from the bogie.
Report any issues to the OCC (Operations Control Center) immediately.
Stop the train immediately and inform the OCC if a problem is found during a roll-by inspection.

Incidents and Irregularities

Report all incidents and irregularities involving molten sulfur and phosphoric acid immediately to the OCC.
Discharged, but not purged, tank wagons or containers are considered hazardous.

Incidents Definition

Fires on locomotives hauling block trains of molten sulfur and phosphoric acid.
Fires on vehicles carrying molten sulfur or phosphoric acid or on vehicles next to them.
Leakage, spillage, or escape of molten sulfur and phosphoric acid.

Incidents and Irregularities with Molten Sulfur and Phosphoric Acid

Incidents are defined as occurrences that could have resulted in a hazard, such as a fire, explosion, or leakage.
Irregularities are defined as occurrences that may not have resulted in an immediate hazard, but could potentially lead to one.
Examples of incidents involving molten sulfur and phosphoric acid include: improperly secured valves, collisions of vehicles carrying these materials, and vehicle or container defects that put the cargo at risk.
Examples of irregularities include labeling or placarding errors, insecure end caps on outlet pipes, suspected incidents where no fault was found, and confirmed and unconfirmed Wheel Impact Load Detector (WILD) activations.

Emergency Action by Train Crew and Other Staff

In the event of an incident or irregularity, train crew, and other staff are to notify the OCC immediately using the emergency button on the GSM-R radio.
Staff should bring the train or shunting movement to a stop in a suitable place, considering the type of hazard, local conditions, and possible actions by the emergency services.
The locomotive should be switched off in accordance with operating instructions.
Sources of ignition should be avoided, and staff should inform the OCC about the details of the accident or incident and dangerous goods involved.
Information on dangerous goods being carried should be readily available for the emergency services.
Upon leaving the locomotive, prescribed PPE should be put on, and staff should move away from the immediate vicinity of the accident or incident.

A prominent ‘Top Fittings’ cover in green (MGA) or red (PPA).

Couplers and Connections

All tank wagons are fitted with class EE (double shelf) couplers, incorporating overrun and underrun protection.
Wagons are ‘single piped’ with only a brake air pipe.
Additionally, there is an ICC cable and dummy coupling.

Train ECP

Wagons fitted with an ECP braking system allowing the train driver to control all wagon brakes simultaneously.
Each wagon fitted with an ECP manifold and a Car Control and ID Device (CCID).
MS wagons fitted with a standalone ECP manifold.

Train ECP: CCID

Red light indicates train line power is on.
Flashing light indicates train line power is off and the CCID is running on battery power.
No light indicates the wagon is de-energized or asleep.

Train ECP Power

Power for the ECP provided via the Inter Car Connector (ICC) cable (also referred to as the train line).
ICC cable operates at 230 volts.
Before connecting the ICC between wagons:
- Break the connection between the loco and wagons, or
- Switch off the train line power.

Handbrake

Wagon fitted with a manual handbrake at the ‘B’ end.
Handbrake operates in the same manner as other SAR wagons but has an electronic sensor.
Electronic sensor provides information on handbrake status to the SAR Train Driver’s fire screen, via the CCID.
CCID passes the handbrake status to the fire screen in the driving cab.
There is no warning alarm or on-screen alert message.
SAR Train Driver must check the event log in the ECP Fire Screen before taking any train onto the main line.

Brake Requirements

If the automatic brake becomes defective, it must be repaired if possible.
If the fault cannot be repaired, the vehicle may continue to its destination if authorized by RSM.
A discharged tank wagon can make another journey to a maintenance facility.
Handbrakes applied to rakes of wagons as follows: 3 handbrakes for 1 - 30 wagons and 10% for 31 and over.
Shunter must ensure the SAR Train Driver has checked the Fire Screen Event Log for handbrake status.

Piston Travel Indicator

Fitted to each bogie, giving visual confirmation that the brakes are applied or released.
Viewed either by looking through the bogie frame or over the top of the bogie.

Piston Travel Indicator: Caution

When the brakes are released, the blocks still touch the wheel.
Difficult to be certain the brakes have released, so check other indicators like the piston travel indicator and handbrake chain.
The handbrake chain will be loose when the handbrake is not applied.

Piston Travel Indicator, Brakes Applied

Indicator showing in the window.

Piston Travel Indicator, Brakes Released

No indicator in the window.

Piston Travel Indicator: Caution

When applying the handbrake, the indicator may not move fully into the window. (Amount of movement depends on individual strength).
Therefore, do not rely on the indicator alone, always check the white links on the handbrake chain as well.
If the handbrake is not applied, the chain will also be loose.

Retainer Valve

The brake manifold/distributer is fitted with a very prominent retainer valve.
Must remain in the vertical position at all times.

Brake Isolation

The Tree Position Retainer Valve MUST NOT be confused with the Brake System Cut Out Cock, which is fitted to the rear of the Manifold/distributer.
In the event of brake damage or defects, they can be isolated to allow the wagon to be moved.

Brake Isolation: Steps

Consult RSM for a decision on isolating or cutting the wagon out.
Turn the cut-out cock to the closed position.
Pull the release valve pull rod (located on each side of the wagon), hold and release it after hearing air exhausting.
The air in the brake cylinder will exhaust and the brakes will release.
Hold the valve pull rod until all the air has been released from the brake system.
Check the piston travel indicator to ensure the brakes have released.

Brake Isolation: Caution

When the brakes are released, the blocks still touch the wheel, making it difficult to be certain that the brakes have released.
Check other indicators:
- Piston Travel Indicator
- Handbrake Chain
- Brake System Cut-out Cock in normal OPEN position
- Cut-out Cock in CLOSED position (brakes are now isolated)
- Brake Release Pull Rod

Brake System Indicators

To ensure brakes have released after an application, visually inspect multiple indicators
Indicators include the Piston Travel Indicator, Handbrake Chain, Brake System Cut-out Cock, and Brake Release Pull Rod
Empty/Load Sensor Arm drops when brakes are applied as a visual indication
The sensor arm has a small air reservoir mounted near the brake manifold

Wagon Features
