Coming soon: City on Rail





Imagine a city that no longer relies on motor vehicles to ferry citizens to work; a city where you park your car and board a train — not because your car broke down, but because the train is faster and more efficient. Imagine a Nairobi where trains use underground tunnels for the 15-minute ride from the city centre to the airport, a Nairobi that does not have kilometre-long traffic gridlocks.




Now stop imagining, for that Nairobi is right here with you. Yes, Nairobi will soon be a city on rail once The Kenya Railway Corporation completes constructing a mega railway station in Syokimau, and the transformation that project will bring to the entire length of Mombasa Road is already attracting investors the way the the new Thika Road did.




Dubbed the ‘Core System,’ the Syokimau station is among the flagship projects outlines in the Kenya Vision 2030 development project and is estimated to cost Sh16 billion. The 100 kilometre-long railway line is the first phase of three, connecting Nairobi to Ruiru, Embakasi Village, Jomo Kenyatta International Airport and Kikuyu.




The railway line will feature new diesel-electric trains with a capacity of 200,000 people per day and a maximum speed of 180 kilometres per hour, contrasting sharply with the current diesel engines that do up to 20 kilometres per hour.




Besides providing fast, reliable, safe, affordable and world class commuter rail services within the Nairobi Metropolitan region, the railway system is also expected to ease congestion on Mombasa Road because some of the traffic will be transferred to the system.




To accommodate the expected surge of motorists opting to go the rail way, the Syokimau Station will have a 1,200-slot parking yard. The current 50 functional train stations serve at least 35,000 commuters daily. Passenger and freight trains servicing the main railway line between Mombasa and Kisumu have a maximum speed of 50 kilometres per hour.




For this, most people would rather brace the traffic on the roads than be on the rail because they consider trains to be too slow. “With the high speed of the new trains, travelling time from the central business district to JKIA will significantly reduce from the current 90 minutes to 15 minutes,” the Managing Director of the Kenya Railways Corporation Nduva Muli said.




It is not just commuters who will benefit from the project. Businessmen too will reap from the completion of the project. This is because the station will have shops and restaurants where passengers can enjoy a cup of coffee as they wait for their ride. Other businesses and trading centres will also rise at the other stations in Kikuyu and Ruiru.




Businessmen have the opportunity to provide bus and shuttle services from the Syokimau terminus to JKIA in just five minutes. The shuttles will operate for a while before the link line connecting Syokimau to JKIA is completed. The 6.5 kilometre-long line will cross Mombasa Road through an underground tunnel at the cost of Sh3.2 billion — the most expensive part of the Core System.





“The Syokimau station will serve mostly residents of Syokimau, Mlolongo, Athi River, Kitengela and Kajiado who will have the option to complete the journey to the Central Business District in comfort by train after parking their cars or being dropped by public means,” Mr Muli said.




But KRC faces two major challenges to the completion of the project: encroachment along the Nairobi–Kibera-Makadara–Embakasi railway corridor and the menace that is matatus and buses blocking the entrance to Nairobi Railway Station.




Discussions are underway with the World Bank, Nairobi City Council and the Ministry of Local Government to come up with a speedy solution. This is the first time since independence that Kenya is building even one metre of rail. The current network was built by Indian slaves and the Imperial British East Africa Company in the 1895.




It began at the Kilindini Harbour along the coast and arrived in Nairobi in 1900. The KRC therefore seeks to not only build new lines but also rehabilitate the current stations. In 2008, the Government of Kenya launched the Vision 2030, a development blueprint aimed at transforming the country into a middle-income state.




The Vision is based on three pillars. The Economic Pillar seeks to improve the prosperity of Kenyans through an economic development programme with the aim of achieving a gross domestic product growth rate of 10 per cent yearly. The Social Pillar intends to build an equal and cohesive society in a clean environment, while the Political Pillar creates a democratic political system that is founded on issue-based politics that respect the rule of law as well as protect the rights of every Kenyan.




The Vision 2030 flagship projects are being implemented in five stages — of five years each — beginning in 2008. The stages are called ‘medium-term plans’ and are, therefore, the pace setters in rapid growth generations.




The 2008-2012 medium-term plan has over 20 flagship projects under various ministries, among them the Syokimau Railway and the Thika Road super-highway. The road is expected to be completed by June next year.




With the deadline for the 2008-2012 medium term plan fast approaching, ministries are in a last minute rush to beat it, implementing as many projects as they can. For that, the government has made significant progress. And the Kenya Railway Corporation refuses to be left behind.




Phase two of the railway project will include an additional 70 kilometres of rail, connecting Thika, Lukenya and Limuru, while the third phase will add 100 kilometres more extending to Ngong, Kiserian, Rongai and Kiambu.




When all three phases are completed by 2030, Nairobi will not just be the city in the sun, but also the city on the rail.

Kshs 2.7 billion in Variations for Thika Superhighway Construction Project





The escalating cost of fuel could increase the cost of completing the Nairobi-Thika highway.




This could result in further delay to completion of the Sh27 billion highway, which is scheduled for February next year.




Roads permanent secretary Michael Kamau said the government had a contingency plan to take care of such a predicament.




“If this project is delayed and the fuel prices continue behaving the way they are doing, then we have serious challenges on the amount of money we are going to pay on the variation on price,” the PS said while inspecting the construction progress.




He, however, said the project was nearly half-way done.




“After we changed the contractors, who were doing the re-routing of the water services, the progress level is at six per cent per month,” Mr Kamau said.




He said the contractors were working on the structural works — the underpasses and retaining walls — but had been set back by the current rains.




The PS urged the engineers to gear towards sectional completion of the road.




He noted that the Museum Hill interchange would be ready by July while the works at the Forest and Limuru roads junction were expected to be completed in August.




“We shall be using the flyovers and the traffic jam experienced there shall be eased,” he said, adding that street lights would be put up later.




The highway is expected to ease traffic congestion in the city. China Wu Yi Company, Sinohydro Corporation Ltd and Shengli Engineering Construction are building the highway.

The Kshs 200Billion Tatu City in Ruiru



Tatu City is a mixed-use environment that will be home to 62 000 residents who will live, work and play within this community and it will host 23 000 visitors every single day.

Background

Nairobi, the largest multicultural city in Kenya, has a population of over three million people. It lies between Kampala and Mombasa, close to the Rift Valley. To the east are the Ngong hills, to the north Mount Kenya and Mount Kilimanjaro to the south-east. The Masai Mara and Amboselli game reserves are within easy reach.



Nairobi's airport, Jomo Kenyatta International, is the largest and busiest in East and Central Africa - with over 49 airlines servicing the Kenyan market. The Eastern Bypass highway, currently under construction, will link the airport to Tatu City.



But with the rapid growth of the recent decades Nairobi has suffered the effects of unconstrained urbanization. The city fathers are now faced with one of two challenges:

  • Rebuild major parts of the city, with all the disruption this involves, or

  • Create a new, modern urban node, as envisaged in the Nairobi Metro 2030 Plan, which encourages relocation of both commercial and residential developments outside of the CBD.




The above challenges are what led the team involved to come up with the idea of 'Tatu City'.

Tatu City is a nodal development – each node contains distinct facilities including open spaces and public environments interconnected by a public transport system as well as pedestrian walkways. The following are the key characteristics:-

  • Low Density Residential Neighbourhoods

  • Medium to High Density Residential Neighbourhoods

  • Primary & Secondary Urban Nodes

  • Central Business Spine

  • Mixed Use Spine

  • Suburban Business Nodes

  • Tourism & Conference Facilities

  • Light Industrial, Warehousing & Infrastructure




Tatu City promises to offer a first-world support infrastructure incorporating the following:

  • Paved Roads & Walkways

  • Potable Water Supply System

  • First World Sanitation

  • Solid Waste Disposal Systems

  • Electricity Supply Systems


A total of ten development phases are envisaged - some of these could be developed simultaneously, as demand requires. The starting point of the entire development concept is the environment, with over 35% of the land set aside for natural green belts. A further 15% has been earmarked for world-class infrastructure development.



The primary focus will be Phase 1 A which comprises the development of the Primary Urban Node, the high density residential precinct directly north of the node as well as a portion of the Tourism and Conference Precinct to the south of the east-west arterial.



Phase 1 B, which lies to the west of Phase One A, comprises of the Techno Park as well as a Low Density Residential Neighbourhood.

Austin-Smith : Lord Vision for Nairobi 2030

In January 2010, a UK-based firm, Austin-Smith:Lord,  together with its Kenyan partners Saad Yahya & Associates and engineering firm Mott Macdonald were shortlisted along with 5 others to develop a concept for the Nairobi 2030 Metropolitan Spatial Plan. Consulting Engineering Services from India Ltd. were the eventual winners.

There are 4 regions that compromise the Nairobi Metro Region area. The city area of Nairobi measures 684 sq kilometres alone, with the larger metro area covering 3,000sq. km. The land of Nairobi’s region falls from the edge of the Rift Valley in the west at an elevation of 2,300 metres, to 1,500 metres to the east of the city, with the centre of the city standing at 1,700 metres. Nairobi was a staging post for agrarian and pastoral tribes. In the early 1900’s the trading boundaries were stretched from Uganda through Nairobi to Mombasa on the coast. The UAE has invested in broadband for all. Digital trade has started.

[caption id="attachment_1302" align="alignnone" width="640" caption="Greening the City: Nairobi River + Kibera"][/caption]

The total population of the Region increased from 1.36 million in 1979 to roughly 3 million in 1999, with an anticipated growth to 5 million by 2015. The last master plan made in 1970 has not been revised since and many of the issues unchecked, unplanned, unresolved some 40 years on.

Consider Africa’s largest informal settlement of Kibera, that has established itself + grown to the west of Nairobi. It is now a locally run organism of houses, shops, schools, surgeries and small businesses. Previously an unhealthy environment, its residents have taken control. There are many such organisms that have grown like viruses across Nairobi attaching themselves to the city’s fringes. Some better, some worse. Can man’s viral instinct - work from the small scale up to the metro scale - contribute to future planning ideas and decision making?

Giraffes and other migrating animals in the national park stand in stark silhouette to the urban back drop of flyovers, traffic and buildings to the adjacent central Nairobi. People walk between home and work because they cannot afford ‘matatu’ taxi’s or buses. Wildlife in the park are stopped in their tracks seasonally because of man’s encroachment on their land. Nairobi was the green capital of Africa.

We wish to re-green the city by opening, improving and cleaning up the city’s arteries. It’s roads, rail, rivers and water ways to allow free passage.

[caption id="attachment_1306" align="alignnone" width="640" caption="Nairobi 2030 Metropolitan Master Plan, Board"][/caption]

We propose small – medium and long distance radius ‘rings’ of infrastructure; systems of road, rail, sewage and clean-water supply and storage. We propose to link new and existing towns across the existing network of roads, river and rail lines, providing each town with it’s own political, economic, social and infrastructural identity.

Nairobi stands at a cross roads.  All Nairobi’s considerable energy, beauty and resource are in balance. Growth and change best happens from within. Any new scheme for the region has to use people and materials sustainably.
