Supply, delivery and offloading of ballast – metrorail gauteng region (PRASA)

This submission is aimed at getting the approval for the appointment of service providers

for the supply, delivery and offloading of ballast in the Metrorail Gauteng region

The Gauteng Region is a network of commuter rail services in Gauteng province in

South Africa, servicing the Johannesburg and Tshwane metro areas. It is operated by

Metrorail, a division of the Passenger Rail Agency of South Africa (PRASA).

Metrorail routes spread out across the province from three main hubs: Park Station in

Johannesburg, Germiston Station on the East Rand, and Pretoria Station. Routes

service central Johannesburg, the East Rand, Soweto, the Vaal Triangle, the West

Rand, central Pretoria, and suburbs to the north, east and west of Pretoria.

2. Background information

1.1. Status quo:

The Permanent way department has embarked on a Perway infrastructure

rehabilitation by means of on-track machine packages that is comprised of ballast

screening machines, Tamping machines, Track stabilizer machines and ballast

regulator machines. Ballast is one of the main materials that is required when

rehabilitation works are in progress and works cannot be possible if ballast is not

supplied as most of the ballast get spoiled as it has reached its lifecycle or rather it

no longer meets ballast quality requirement.

1.2. Problem statement:

PRASA is required to ensure that infrastructure is maintained and in good operational

condition that conform to the required operating and safety standards, screening has

not been executed in a very long time and this poses a safety risk on Perway

infrastructure as ballast main purpose is to bear and distribute load; facilitate water

drainage and to control vegetation which might interfere with the track structure.

It has also come to light that some of the areas are experiencing shortage of ballast

due to lifespan, washaways caused by flooding during the rainy seasons which

sometimes leads to service disruptions, ballast contamination caused by illegal

trenching which led to poor drainage and service disruption. The procurement of

ballast is urgently required, so that the department can be able to carry routine

maintenance which will improve safe passage of trains and mitigate potential

incidents and train delays.

3. Objective of the proposed project

1.4. Desired outcomes for carrying out the proposed project

The project aims to restore the Perway infrastructure to enable the safe running of the

train service. This will therefore assist PRASA in achieving its primary mandate of

providing a reliable rail transport service to Gauteng commuters and enable the

business to collect fare revenue from those commuters.

1.5. Project benefits to PRASA

In line with the PRASA strategic objectives and Operational effectiveness, Perway

department aims to achieve continuous Perway service improvement and reliable track

network. This can be achieved through the proactive management and procurement

of ballast required to support the track infrastructure, in order to render a safe and

reliable train service.

By restoring the Perway system to its design specification, maintenance cost, train

disruptions that are due to the Perway system failures will be reduced thus improving

the service offering.

1.6. Current mechanisms in place to address the problem

There’s no active contract for supply and delivery of ballast which hinders the effort to

rehabilitate Perway infrastructure.

A3.1 Place the specimen in a porcelain dish and cover fully with test

solution between 20 o C for 7 h. Decant the solution taking care that no stone

is lost.

A3.2 Dry the specimen for 15 h at 105 o C. Allow the specimen to cool for 2

h. This completes one cycle of the soundness test.

A3.3 Repeat the cycle described in A3.1 and A3.2 as often as specified.

After every fifth cycle, wash the specimen on a 1,70 mm sieve with hot water

until no crystalline sodium sulphate is visible and continue the test with

material retained on a 1,70 mm sieve.

A3.4 After completion of the final cycle, wash the specimen in hot water

until the washings are free of sodium sulphate. Dry the specimen to constant

mass and screen on a 1,70 mm sieve. Let the mass retained on the sieve be

M2.
