Parking and DFDS
Capacity
![Page 17: Capacity management in large projects](https://reader033.fdocuments.in/reader033/viewer/2022042723/587337db1a28abf21b8b4c11/html5/thumbnails/17.jpg)
Capacity Problems– Rail
Capacity• Link loads reach maximum between Centurion and
Sandton
• Highest link load in Midrand – Marlboro section
• Capacity under pressure for about 1½ of the 3 hour
peak period per day
• Counter flow services are underutilised
• Options on current train timetable exhausted
• Rolling stock availability under pressure
• Challenge is how to alleviate capacity constraints
![Page 18: Capacity management in large projects](https://reader033.fdocuments.in/reader033/viewer/2022042723/587337db1a28abf21b8b4c11/html5/thumbnails/18.jpg)
Capacity Problems– Rail Layout• A double-line section shared by the North-South and
East-West
• Junctions at Marlboro Portal - East-West and North-
South services are merged / diverged.
• Single-line tunnel sections between Sandton and
Rosebank
• An at-grade crossing between Pretoria and Hatfield
• Scheduled crossing in the platforms at Rosebank
Station
• Terminal stations restricted to two platforms each
• No loop lines outside the depot area
• Long signalling blocks
![Page 19: Capacity management in large projects](https://reader033.fdocuments.in/reader033/viewer/2022042723/587337db1a28abf21b8b4c11/html5/thumbnails/19.jpg)
Capacity Problems– Parking &
DFDS• Parking
• Parking capacity is insufficient - Pretoria, Centurion,
Midrand, Park, Rosebank and Rhodesfield.
• Availability of land at stations
• Cost of development vs Recovery/Cost to customers
• DFDS
• J2 Johannesburg CBD and M3 Sunninghill-
Overcrowding
• Long bus cycle times
• The DFDS bus service footprint
![Page 20: Capacity management in large projects](https://reader033.fdocuments.in/reader033/viewer/2022042723/587337db1a28abf21b8b4c11/html5/thumbnails/20.jpg)
Considerations
&Conclusions
![Page 21: Capacity management in large projects](https://reader033.fdocuments.in/reader033/viewer/2022042723/587337db1a28abf21b8b4c11/html5/thumbnails/21.jpg)
Capacity Problems– Trade-off
Consideration• Longer trains are more labour efficient
• Shorter trains are more energy efficient
• Pressure on the available line capacity of the network
• • Higher capital and maintenance costs
• The capital cost of doubling of an existing single tunnel
• Higher service levels/ Consequential delays
• Seating Capacity ratio of 1.50 vs. 1.3 vs Cost of service
• Jumper/step back drivers could alleviate capacity
problems on platform and line capacity.

Capacity – Assessment &
Conclusions Rail• That 84 additional rolling stock coaches - required by 2026
• Longer platforms would be required at OR Tambo - 2013
• The Rosebank to Park Station single tunnel - full capacity
by 2022
• The Sandton to Rosebank single tunnel, full capacity by
2026
• Staging capacity at maintenance depot in Midrand -2016
• The provision of additional line capacity between Marlboro
portal and Sandton - required by 2029
• high level junction capacity at Pretoria station - reach
capacity by 2018.

Assessment & Conclusions
Stations, DFDS & Parking• The station design capacities under pressure
• OR Tambo Station (from 2013),
• Park station entries (2014),
• Midrand Station entries (2015),
• Sandton Station exits (2016).
• Additional parking would be required at seven of the nine
station in the next 5 years
• Centurion (824),Rhodesfield (535),
• Midrand (363), Pretoria (253),
• Hatfield (187), Rosebank (148) and Park (70).
• Adititonal busses and routes will be required by 2019

Capacity – Recommendations• 48 rolling stock coaches are procured starting 2015
• OR Tambo platform be extended - 2014
• Rosebank to Park and Sandton to Rosebank single tunnels be
doubled - 2021
• New Depot Staging capacity at the depot in Midrand to be
increased
• Line capacity between Marlboro and Sandton is increased by
2018
• Investigate Centurion – Sandton short turn shuttle service
• A full simulation study of the system to determine bottlenecks
• Configure the seats in GPS train sets – 2014
• Shorter headway and the rolling stock implications
![Page 26: Capacity management in large projects](https://reader033.fdocuments.in/reader033/viewer/2022042723/587337db1a28abf21b8b4c11/html5/thumbnails/26.jpg)
Capacity - Future actions• Network Assessment will be updated on an annual basis
• Integrate land-use strategies for all stations
• Determine the long-term GMA financial implications
• A full transport integration strategy to be finalised
• Prioritise the different activities and create a scheduled
project plan
• Finalise the rolling stock procurement tender
• Finalise the physical infrastructure system optimisation
• Finalise new DFDS routes and add new shuttle services
• Develop a full integrated plan to incorporate NMT and UA
