8.1.1 PROJECT R-CE-1: RAIL UPGRADING: LÜDERITZ RAIL
188.8.131.52 DESCRIPTIONThe project has been divided into two phases. The first phase covers a period of up to 12 months and the second phase the period thereafter.
The activities which have been identified for completion in the first phase will ensure the necessary acceleration of the ongoing upgrading programme by providing manpower and equipment to replace the weakest sections of the track and formation. A reception/ dispatch yard will be constructed at Lüderitz and the turntable overhauled (under construction during mid-1991).
During the second phase all outstanding rerailing, resleepering and ballasting will be completed and bridges strengthened in order to permit the passage of 16,5 t axle load waggons.184.108.40.206 BACKGROUND AND NEED FOR THE PROJECT
This project is part of a package of projects, which in addition includes projects R-CE-2, R-CE-3, R-CE-4, R-ST-1, P-CE-1, P-CE-2, P-ME-1 and P-ME-2. The purpose of the package are (i) to upgrade the port of Lüderitz to transform it into a commercial port able to serve primarily coastal traffic with neighbouring states, and (ii) to upgrade the branch railway line between Seeheim and the Port of Lüderitz.
The Seeheim to Lüderitz line is constructed with a mixture of rail sections ranging from 18,26 kg/m to 48 kg/m (originally: 18,26 kg/m Krupp: 42,32 km; 22 kg/m Krupp: 19,00 km; 30 kg/m CGR: 8,71km; 30 kg/m SATS: 66,91 km; 40 kg/m SATS: 1,30 km and 48 kg/m SATS: 0,85km), and a variety of steel, concrete and timber sleepers. A TransNamib (TNL) rehabilitation project is presently in progress utilising materials recovered from the main line Nakop-Windhoek during the upgrading project. Much of the recovered material is laid alongside the track and a TNL relaying gang is assigned to the line. The following sections have been rehabilitated during 1984 to 1991/92: km 185,3-192,3 (Aus: km 179,27); km 215,20-217,00; km 232,20-238,80; km 246,50-252,50 and km 291,00-306,00 with a total of 32,80 km and 5,80 km for 1991/92 (km 275,80-281,60). It has also to be stated that the approximate total Revenue was R 461.000 and the approximate total Expenditure for 1990/91 for the Aus-Lüderitz section.
The section Seeheim to Aus is of a fair standard, suitable for 15 t axle load traffic at speeds of up to 60 km/h. From Aus to Lüderitz axle loads are restricted to a maximum of 11,5 t and line speeds to 30 km/h on many sections.
After the repair and upgrading project has been completed, the line will be of a good branch line standard, enabling increased use to be made of the port of Lüderitz.220.127.116.11 PROJECT COMPONENTS AND IMPLEMENTATION

The project costs are estimated as follows:
US $ million
First Phase 6,0
Second Phase 3,0
Total 9,0 ============
The project is contingent on projects R-CE-2 (Establishment of Quarry) and R-CE-4 (Bridge Strength Survey). It has priority 2 (priority rating: see above). The project should be implemented by TNL.
8.1.2 PROJECT R-CE-2: ESTABLISHMENT OF QUARRY
The project comprises the establishment of a ballast quarry in order to provide a supply of ballast for the upgrading of the Seeheim-Lüderitz railway branch line.
18.104.22.168 BACKGROUND TO THE PROJECT
At present, ballast is provided for the southern region of the rail network from a commercial quarry at Keetmanshoop (Dolerite Quarry).
As less than half of the Seeheim - Lüderitz line is ballasted (none on the section from Aus to Lüderitz), there is a need to provide approximately 253.000 m3 of ballast. A proportion of this will come from the Keetmanshoop quarry but as the distance to the western end of the line will cause disruption to traffic and will be expensive, it will be necessary to open a new quarry along the Aus-Lüderitz section.
22.214.171.124 PROJECT COMPONENTS
The project comprises the supply and installation of the following:
- One semi-mobile crushing plant capable of producing
60.000 m3 of ballast a year;
- Power plant, conveyors and screens;
- Drills, compressors, loading shovels and dump trucks;
- Spare parts for the two year operation.
126.96.36.199 PROJECT COSTS AND IMPLEMENTATION
The project costs are estimated to be US $ 3,5 million. The project has priority 2 (priority rating: see above).
8.1.3 PROJECT R-CE-3: REALIGNMENT STUDY: RAILWAY
The purpose of the project is to carry out a study to determine the possibility of realigning the section of the Seeheim-Lüderitz line between the stations of Rotkop and Oil Sites near Lüderitz in order to provide a route which is clear of moving sand dunes and has a more stable formation which will not be subject to washaways.188.8.131.52 BACKGROUND TO THE PROJECT
The section of the Seeheim to Lüderitz line from Rotkop down to Lüderitz passes through an area of moving sand dunes, which frequently cross the track, and for the last 12 km follows the course of a dry river valley which is subject to flooding after periods of heavy (seldom occurring) rainfall. The existing formation is very weak and liable to collapse every time a flood occurs.
If an alternative route can be found it may be possible to justify the construction of a realigned section of track which will not be subject to blockage and will be more secure in the rainy season.184.108.40.206 THE STUDY
The study should involve:
220.127.116.11 STUDY COSTS AND IMPLEMENTATION
- Using existing maps to establish the optimum route for the
line from Rotkop to Lüderitz;
- Survey of the route;
- Design of a realignment scheme and estimation of
The study cost is estimated to be US $ 0,2 million and work should be commenced during 1991 (priority 2) (priority rating: see above) in order to establish the viability or otherwise of a realignment if there is the requirement to make increased use of Lüderitz Port.8.1.4 PROJECT R-CE-4: BRIDGE STRENGTH STUDY: RAILWAY
The project is for the inspection and testing of all bridges on the Seeheim - Lüderitz branch line to ensure that they have the required load resistance to carry a 16,5 t axle loading. Repair, strengthening or new designs in case of replacements, if any, are to be prepared.18.104.22.168 BACKGROUND TO THE PROJECT
The Seeheim - Lüderitz railway branch line is proposed to be upgraded to an appropriate branch line standard. When completed, the track and formation will be able to support trains with 16,5 t axle loads.
There are 343 structures (bridges and culverts) on the line which may or may not be strong enough to resist the loads of heavier trains. A survey is necessary to determine the strength and condition of each of the structures and to determine repair or replacement works that should be carried out to ensure that they are capable of carrying the increased loading.22.214.171.124 THE STUDY
The study would include:
126.96.36.199 PROJECT COSTS AND IMPLEMENTATION
- Review of all structure drawings and design documentations;
- Inspection of all structures;
- Load testing of critical structures;
- Preparation of structure reports;
- Design of repairs, strengthening or replacement works.
The project is estimated to cost US $ 0,1 million and should be completed during 1991/92 (priority 2) (priority rating: see above).8.1.5 PROJECT R-ST-1: RADIO CONTROL SYSTEM
Radio survey of the Seeheim - Lüderitz line and the extension of the radio control system to cover the line.188.8.131.52 BACKGROUND TO THE PROJECT
TNL has replaced the old token block system of train control on the main lines with a radio control system. The system operates presently to Keetmanshoop and will be extended to the southern border of Namibia by the end of 1990.
At present there are so few trains operating on the Seeheim - Lüderitz line that the wooden staff system of train control is quite adequate. However, there is little flexibility inherent in the wooden staff system, and if traffic increases it will have the effect of limiting line capacity and hence restricting the development of the line. A simple, relatively cheap form of radio control will be suitable for the line and it would therefore be logical to extend the system used on the main lines to cover the Seeheim - Lüderitz branch line.184.108.40.206 PROJECT COMPONENTS
Project implementation would involve:
220.127.116.11 PROJECT COSTS AND IMPLEMENTATION
- Radio survey of the line;
- Supply and installation of a control console at
- Supply and installation of radio masts, repeater equipment
and radio receiver/transmitters at stations, on locomotives
and on maintenance vehicles.
The project is estimated to cost US $ 0,3 million and should be implemented during 1991/92 (priority 2) (priority rating: see above).8.2 PORT PROJECTS
8.2.1 PROJECT P-CE-1: DREDGING AT LÜDERITZ PORT
The project comprises maintenance dredging of existing dredged area at Lüderitz to regain existing levels as well as additional dredging to increase the capacity of the port.18.104.22.168 BACKGROUND TO THE PROJECT
The access channel to the jetty, and turning areas around the jetty, were dredged when the jetty was constructed in 1968. It is understood that maintenance dredging has been carried out at intervals, but a recent survey has indicated that siltation has now reached an unacceptable level.
It is proposed that the material dredged from the harbour should be used to increase the area of the storage yard, so that a reasonable quantity of containers and general cargo could be stored within the port. Dredging to -7,0 m (or -7,5 m if rock levels permit) in an area at the head of the jetty would permit ro-ro vessels with straight ramps up to about 9.000 dwt to discharge on to the existing jetty.22.214.171.124 PROJECT COMPONENTS
The project comprises:
126.96.36.199 PROJECT COSTS AND IMPLEMENTATION
- Dredging approx. 50.000 m3 of fine material from existing
dredged areas to regain previous dredged depth of -6,1 m.
The fill would be placed in reclamation on the adjacent
shoreline, and rocks protection would be required to contain
- Deepening of dredged area at head of jetty to -7,0 m (or -7,5
m if rock levels permit);
- Dredging to -1,5 m for new lighterage wharf (Project
The dredging should be carried out as soon as possible, following international tendering (priority 1) (priority rating: see above). The costs are estimated to be US $ 1,0 million of which about 30 per cent would be for mobilisation and demobilisation of the dredger.8.2.2 PROJECT P-CE-2: IMPROVEMENTS TO LÜDERITZ PORT AREA
Surfacing of storage areas, construction of a ro-ro facility, construction of lighterage wharf and relaying of existing railway sidings.188.8.131.52 BACKGROUND TO THE PROJECT
The existing land-side area of Lüderitz is covered by railway sidings, with little area available for the storage of containers and general cargo. The existing railway sidings should be rationalised and roads and storage areas formed.
At the present time lighters are off-loaded at the main jetty. In order to free the main jetty to take coasters and ro-ro vessels a lighterage wharf would be constructed alongside the reclaimed area provided under Project P-CE-1. The construction of a fixed ro-ro ramp on the side of the existing jetty would permit use by coastal ro-ro vessels.184.108.40.206 PROJECT COMPONENTS
The project would include:
220.127.116.11 PROJECT COSTS AND IMPLEMENTATION
- Re-lay existing railway sidings, construct roads and surface
container storage area and new storage area;
- construct sheet piled ro-ro ramp on the side of the existing
- construct sheet piled lighterage wharf adjacent to new
- structural survey and design check of the existing jetty.
The works in this project should be constructed under a single local contract and be completed in the medium term (priority 2) (priority rating: see above).
The costs of this project is estimated to be:
US $ million
Re-laying railway sidings
Roads and surfaced areas 0,30
Ro-Ro ramp 0,40
Lighterage wharf 0,60
Structural survey of jetty 0,10
Provision of a new tug and four flat-top lighters.18.104.22.168 BACKGROUND TO AND NEED FOR PROJECT
At present Lüderitz has one tug, a small harbour tug, and five traditional lighters (which are not suitable for containers). The existing tug is reaching the end of its service life, and a second tug would be useful for handling lighters. The provision of flat-top lighters would permit the handling of containers from all types of vessels.22.214.171.124 PROJECT COMPONENTS
The project comprises:
126.96.36.199 PROJECT COSTS AND IMPLEMENTATION
- Supply of one 900 hp tug;
- Supply of four flat-top barges 28 m x 7 m x 1,5 m.
The equipment should be provided at the same time as the new cargo handling equipment (Project P-ME-2). The project has priority 2 (priority rating: see above).
The cost is estimated to be:
US $ million
Four lighters 0,35
Provision of cargo handling equipment at Lüderitz.188.8.131.52 BACKGROUND TO AND NEED FOR PROJECT
The only cranes available at present at Lüderitz are two rail-mounted 3 t quay cranes, which are in poor condition. It is proposed that a small quantity of cargo handling equipment be provided, which could be supplemented as the need arises.184.108.40.206 PROJECT COMPONENTS
Supply of the following equipment:
- 1 mobile port tower crane, capacity 24 t at 6 m;
- 1 heavy duty fork-lift truck, to stack 30 t containers 3 high and
work inside ro-ro vessels;
- 1 medium duty fork-lift truck, to stack empty containers 4
- 3 small fork-lift trucks;
- 1 general purpose 10 t crane;
- 3 tractor units;
- 10 trailers (container flats and general purpose).
The equipment should be provided to coincide with the completion of the port improvements Project P-CE-2, and has priority 2 (priority rating: see above). The cost of the equipment is estimated to be US $ 2,0 million.
