TRC tests new SGR system
DAR ES SALAAM: THE Tanzania Railways Corporation (TRC) is making significant strides in its electric train project as it continues to conduct comprehensive tests on its Electric Multiple Unit (EMU) train.
The EMU, a modern and efficient train designed to enhance rail transportation in Tanzania, is currently undergoing rigorous trials along the 444 – kilometre route between Dar es Salaam and Dodoma.
According to Kelvin Kimaro, the TRC Mechanical Engineer, the latest phase of testing is focused on evaluating the EMU’s performance through tunnels, which could cause discomfort to passengers, particularly affecting their ears.
“We are closely monitoring factors such as noise levels, pressure and overall passenger comfort to ensure the train’s safety and reliability.
“The aim of this measure is to further examine whether the train can handle longer distances, especially through tunnels. We have installed microphones and various equipment to monitor noise levels and assess any impact on passengers, ensuring their safety,” Eng Kimaro said.
The trials involve a series of tests, including assessments of the EMU’s air conditioning system, lighting, electrical supply, braking system and propulsion system.
“We are conducting a total of 12 different tests to ensure that every aspect of the train is functioning optimally,” Eng Kimaro added.
Despite the positive progress, the TRC has encountered some challenges during the testing process. One such issue is an unusual noise that the contractor is currently investigating.
Additionally, as this is the first set of EMUs out of ten, the trial process has taken longer than anticipated. However, the TRC expects to expedite the testing for the remaining sets once the initial trials are completed.
He further outlined the differences between the EMU and other electric trains, saying the EMU is a unified unit, meaning its parts cannot be separated, unlike other trains that can be divided into sections. It also offers two classes of service: Economy and Business.
One set of EMU consists of two locomotives and eight passenger coaches with a capacity of carrying more than 500 passengers. The EMU trains are powered by electric traction motors embedded within the carriages, eliminating the need for a separate locomotive.
Eng Kimaro said Business Class features spacious and adjustable seats, while the Economy Class provides comfortable and affordable travel. The EMU also includes a toilet designed for passengers with special needs and amenities for mothers traveling with infants.
The first set of EMUs that arrived in Tanzania in April this year was procured from the South Korean Hyundai Rotem engineering firm. The EMUs are equipped with automatic speed control and can operate on 20Kv power supply from the grid.

The TRC’s investment in the EMU trains is part of its broader plan to modernise the country’s railway infrastructure and improve transportation services. The EMUs are expected to play a crucial role in connecting major cities, boosting the country’s economic development.
In July 2021, TRC awarded Hyundai Rotem a 335.4bn/- contract to supply 10 EMUs for the Standard Gauge Railway, meant for use in the Dar es Salaam to Morogoro and Makutupora sections.
Meanwhile, the Manager of Samia Train Station in Dodoma, Festo Mgomapayo, shared that the station has been operational since July 25 of this year.
“We operate four electric train trips daily, with two departing from Dodoma to Dar es Salaam and two from Dar es Salaam to Dodoma. The express train can carry over 900 passengers and the service has been warmly received by the public,” he said.
To ensure security and prevent fraud, ticket and ID verification processes are strictly enforced. “Every passenger must present an identification document and for those who do not have one, introduction letter from local government authorities is required for identification,” Mgomapayo added.
