The response came after a netizen questioned why a railway corporation was launching a bus service arguing that rail was supposed to be the solution to road traffic congestion rather than a contributor to it.
The post resonated with many Nairobians who found the concept confusing.
Kenya Railways addressed the concern directly saying the BRT service is designed to complement rail operations by improving first and last-mile connectivity.
"This integrated approach supports our goal of easing overall traffic congestion by encouraging greater use of rail," the corporation stated.
Another member of the public raised concerns about whether BRT buses cause delays in getting commuters to railway stations on time.
Kenya Railways responded by explaining that it operates link trains specifically to ensure streamlined transfers and minimise delays between bus and rail connections.
The Nairobi Link Train is a commuter service connecting Nairobi Central Railway Station to the SGR terminus in Syokimau.
It runs daily timed to coincide with Madaraka Express arrivals and departures taking roughly 20 to 30 minutes for a seamless transfer between the two services.
The Nairobi Railway City serves as the main hub where commuter trains BRT lines and light rail converge.
This integrated design significantly increases overall passenger capacity and creates a coordinated transport network rather than a collection of competing services operating in isolation.
Two BRT corridors anchor the network. The electric 12.4 kilometre Chui Line connects hospitals and Dandora station while the Simba Line runs along Thika Superhighway linking Ruiru to the CBD and Kenyatta National Hospital.
Both lines use dedicated corridors that are separate from the routes used by ordinary public service vehicles.
By operating on dedicated corridors the BRT buses avoid the congestion that plagues regular matatus and buses on shared roads.
This separation is central to the system's design and is what allows it to deliver predictable and faster journey times for commuters feeding into the rail network.
Kenya Railways says the long-term goal is to shift more Nairobians away from private cars and matatus toward an integrated public transport system where buses and trains work together as one seamless service across the city.
