One of two passenger trains from Nanyuki to Nairobi temporarily stalled on Sunday at Ruthagati with more than 1,500 passengers on board.
Kenya Railways MD Phillip Mainga said one of the trains stopped after the crew noted an issue.
“The crew noticed a mechanical issue with the train that is why they stopped to address it. However, they resumed their journey without more hitches," Mr Mainga said.
The Nanyuki-Thika trains which stop at Inter-terminus in Murang’a, Makuyu, Maragua, Sagana, Karatina, Kiganjo, Chaka, Naromoru and Nanyuki stations charge low fares of between Sh50 and Sh100.
Locals have opted for railway services during the festive season due to the low fares, leading to Kenya Railways increasing the number of trains commuting the route.
Kenya Railways (KR) announced on Sunday that it would double the number of trains from Nanyuki to Nairobi to cater for the high demand for passenger service on the route.
The launch follows a successful test run on July 7 between Thika, north of Nairobi, and Nanyuki as freight services on the line were reintroduced in August, and transport goods.
