Hundreds of commuters were on Monday morning stranded after the Rift Valley Railways suspended train services due to technical hitches.
The technical hitch is said to have started midnight and extended upto Monday morning causing a traffic snarl up along Mombasa road.
The areas affected include Syokimau, Imara Daima, Makadara, Kikuyu, Kibera, Embakasi and Ruiru routes.
Commuters complained they were not informed of the changes which forced them to seek alternative means of travel.
An attempt to reach the Railway Station managers remained futile.
This comes after the Railways corporation announced a two-year plan to upgrade its Nairobi infrastructure at a cost of Sh5 billion, in a move seeking to raise commuter numbers tenfold.
Managing director Atanas Maina said the project has already commenced with the upgrade of the Ruiru station.
On Thursday, an unmanned train caused panic along the Nairobi-Ruiru railway evening as it sped towards Githurai.
Police said the train had stopped at the Makadara station awaiting to have wagons attached when the driver, who was in his cabin, realised the pressure was low and the brakes were not working.
