Annexure A
General Information & RFP Requirements
1. Background to Transnet and Transnet Engineering
Transnet, a state owned entity, is the largest and most crucial part of the freight logistics chain
that delivers goods to each and every South African. Every day Transnet delivers thousands
of tons of goods around South Africa, through its pipelines and both to and from its ports. It
moves that cargo on to ships for export while it unloads goods from overseas.
Transnet’s vision and mission is to be a focused freight transport company, delivering
integrated, efficient, safe, reliable and cost-effective services to promote economic growth in
South Africa. Transnet aims to achieve this goal by increasing its market share, improving
productivity and profitability and by providing appropriate capacity to its customers ahead of
demand.
Transnet is fully owned by the South African government but operates as a corporate entity
aimed at both supporting and contributing to the country’s freight logistics network. It aims at
developing South African industry, reducing the cost of doing business, while at the same time
operating efficiently and profitably.
Transnet owns a fleet of more than 2,200 locomotives and 72,000 wagons. Railway lines in
South Africa have a cumulative distance of 20,953 km, of which 8,437 km are electrified to
either 3kV DC, 25 kV AC, or 50kV AC.
Transnet Engineering, the issuer of this RFP, is a division of Transnet focusing on
maintenance and manufacturing of rolling stock and rail related products. It also focusses on
the development and integration of custom products into Transnet operations and rolling stock.
Recently, Transnet Engineering has opened a Research and Development Department for
the purpose of introducing new and revolutionary technology to the rail industry in the South
African and African markets. Transnet Engineering is the engineering backbone of Transnet
and serves the purpose of supplying Transnet with sound technical information for strategic
decision making.
2. Introduction to RFP
Energy security and increasing electricity cost pose a high risk to business. As such, strategic
energy initiatives and smart energy control are some methods of ensuring savings within this
domain without having to rely on the local electrical utility for support.
Energy solutions can be implemented within a number of spaces in the rail environment, such
as: on-board, wayside and facility spaces. Accordingly, Transnet is dedicated to continuous
development of competency in the energy solutions and application space.

Date: March 2017 Page: Page 16 of 20
(TC) Total Compliance: When currently, information is readily
available.
(PC) Partial Compliance: To state that the current information
obtainable only provides partial compliance to the clause. In such a
case, bidders must specify discrepancy and elaborate as to the reason
for their partial compliance.
(NC) No Compliance: To state that the clause is not met currently and
not an option at all.
6.1.4. Any clause not having a response will be regarded as “No Compliance”
response from the bidder. This might cause the immediate disqualifying of
the bidder pending a decision from the tender evaluation board of Transnet
Engineering.
6.2. Alternatives Offered
6.2.1. In addition to offers which in the first instance comply with the requirements
set forth in this technical specification, bidders may also offer, as
alternatives, variations of detail that they consider might be both
advantageous and acceptable to TE.
6.2.2. This will include existing approved units that are already used in railway
and facility applications, and it is accepted that these units will not have
the same additional functionalities as the new designed offers. In all
instances where alternatives are offered for consideration, the following
information shall be furnished:
The same amount and extent of information, comments and data
applicable to the original component offered.
The detailed reasons for offering the alternative(s).
The detailed implications in terms of price, reliability, maintenance
considerations, local stock holding, performance, etc. in comparison
with the basic offer. A bidder need not submit a fully compliant offer
should they truly feel that they have a better solution but TE’s
engineers may reject the offer out of hand if the information supplied
does not meet a cursory approval.
