The Kenya Standard Gauge Railway (SGR) is a railway system that will connect Kenyan cities, and link the country to the neighboring country of Uganda, and through Uganda, to South Sudan, the Democratic Republic of the Congo, Rwanda, and Burundi. There are also plans to link to Addis Ababa, in neighboring Ethiopia to the north. The first segment, between Mombasa and Nairobi, opened passenger rail service in June 2017, and freight rail service in January 2018. Other segments are under construction or planned. The new Standard Gauge Railway (SGR), is intended to replace the old, inefficient metre-gauge railway system.^[1][2][3]

Location

The railway system consists of several major sections:

Mombasa–Nairobi Section

This section, measuring 609 kilometres (378 mi), is known as the Mombasa–Nairobi Standard Gauge Railway, and connects the port city of Mombasa and Nairobi, the capital and largest city of Kenya.^[1] Passenger rail services between Mombasa and Nairobi started on 1 June 2017, and freight rail services on 1 January 2018.

It was built between October 2016 and January 2018, by China Road and Bridge Corporation, at a cost of US$3.6 billion, 90 per cent of which was borrowed from the Exim Bank of China, with the Kenyan government providing the remaining 10 per cent.^[4]

Nairobi–Naivasha Section

This section was also contracted to the company that constructed the Mombasa–Nairobi Section. The line stretches from Nairobi to Naivasha, a distance of about 120 kilometres (75 mi), at cost of KSh. 150 billion (US$1.5 billion), borrowed from the China Export-Import Bank. Construction began in 2018 and the line was officially opened for passenger train service in October 2019.^[5][6] International freight for neighbouring countries interchanges at the Naivasha Inland Container Depot.

Naivasha–Kisumu Section

This section, measuring 267 kilometres (166 mi), stretching from Naivasha to Kisumu, on the eastern shores of Lake Victoria, is contracted to China Communications Construction Company, at a budgeted cost of KSh. 380 billion (US$3.8 billion), borrowed from China Exim Bank.^[7] Loan papers between Kenya and China were scheduled for signatures in September 2018, but were deferred until a commercial viability study is conducted on the entire Mombasa–Kisumu railway.^[8]

Kisumu–Malaba Section

This section, measuring approximately 130 kilometres (81 mi), takes the SGR line to the town of Malaba, at the international border with Uganda.^[9] CCCC, is the contractor for this section as well. The contract price for this section is about KSh. 169 billion (US$1.69 billion). The price for the Naivasha–Kisumu–Malaba section is KSh. 549 billion (US$5.49 billion) and includes the laying of railway tracks in both sections, dredging and expansion of the port of Kisumu, and the expansion and modernization of the inland container depot at Embakasi, in Nairobi.^[7]

Lamu–Lokichar-Nakodok Section

This railway line, totaling 1,500 kilometres (932 mi), is a component of the Lamu Port and Lamu-Southern Sudan-Ethiopia Transport Corridor (LAPSSET) development project. Under the LAPSSET plan, this line would be extended to Juba in South Sudan.^[10]

Nairobi–Moyale Section

This 700 kilometres (435 mi) section also falls under the LAPSSET program. It extends from Nairobi to Moyale, at the international border with Kenya's northern neighbor. It is planned to be extended to Addis Ababa, the capital city of Ethiopia.^[11]

Naivasha–Lokichar Section

This proposed railway link, measuring an estimated 460 kilometres (286 mi),^[12] would link the two main standard gauge railway systems in Kenya; the Mombasa–Malaba SGR System and the Lamu–Nakodok SGR System.^[2]

Overview

This 1435 mm (4 ft 8+1⁄2 in) railway line is intended to ease the transfer of goods and passengers between the port of Mombasa and the cities of Nairobi and Kisumu, in Kenya, Kampala in Uganda, Kigali in Rwanda and subsequently to Bujumbura in Burundi, Juba in South Sudan and to Goma and Bunia in the Democratic Republic of the Congo.^[1][2][3]

In March 2019, during a state visit to Kenya, President Yoweri Museveni of Uganda and his host, President Uhuru Kenyatta of Kenya, jointly, publicly committed to extend the Standard Gauge Railway (SGR) to Kampala via Malaba.^[13][14]

The Kenyan government in 2020 reached a deal with AfriStar to take over operations and maintenance by May 2022.
