Huawei has announced that the railway operational communications network it built for Kenya’s Mombasa-Nairobi rail project, popularly known as the Standard Gauge Railway or SGR, has been put into commercial use.
Huawei’s Digital Railway Solution enables multiple communications tasks, including mission-critical train dispatch, emergency communications, section maintenance communications, secure transmission, and ensures stable power supply along the entire line. The solution will meet customer requirements for safe, stable, and efficient railway operations and ensure highly reliable communications for the railway.

As the first new line to be constructed in Kenya since the colonial line which was built over a century ago, the Mombasa – Nairobi stretch of the railway runs across Kenya from the southeast to the northwest, starting from Mombasa, the biggest port along the east coastline of Africa, to Nairobi, Kenya’s capital.
The SGR line is part of a long-term plan to connect a vast network of rails from Kenya, through Uganda and Burundi, and up to South Sudan. This railway artery in East Africa will provide convenient transportation and promote regional collaboration, integration, economic growth, and social development.
Huawei’s Digital Railway Solution provides the Mombasa-Nairobi Railway with a full suite of core systems such as a highly-reliable, industry-leading railway operational communications system, a large-bandwidth unified transmission system which adopts soft and hard pipes to protect train control and other mission-critical services, a modular and highly efficient power supply system, and an environment monitoring system which enables great scalability and intelligent management. The core systems ensure safe train operations.
Huawei’s next-generation GSM-R solution has been deployed to build the train-to-ground communications network. With end-to-end redundancy backup and 99.999% availability, the network guarantees stable transmission of train control signals. Based on mature hardware platforms, the next-generation BTS3900 GSM-R base stations support smooth migration to LTE-R. The transmission network uses Huawei’s cutting-edge Hybrid MSTP transmission devices that support SDH/IP dual planes.
The SDH hard pipes and IP soft pipes comprehensively bear multiple services without compromising the reliability of mission-critical service transmission. In addition, Huawei’s premium communication power supply and Uninterruptible Power System (UPS) products are installed to meet diversified customer requirements on backup power, ensuring high-quality power supplies for communications systems, data centers, security systems, and other critical loads.
It is expected that the safe and efficient operations of the Mombasa – Nairobi Railway will significantly support Kenya’s passenger and freight transportation, and the subsequent economic growth.
To date, Huawei’s Digital Railway Solution has been deployed to serve more than 100,000 kilometers of railway worldwide. The solution has supported major digital railway projects including those in Germany and South Africa, as well as high-speed rail lines in China and Spain.
