When travelling using the Madaraka Express on the Standard Gauge Railway (SGR), you might have seen some casings along the railway lines that are rectangular in shape and might mimic a coffin.

Kenya Railways has clarified that the structures are casings used to hold the Madaraka Express trains, following public curiosity after they were spotted at the Railway Exhibition during the Mombasa ASK Show.

The clarification came as Kenya Railways highlighted facts about Kenya’s railway network during the show, including the country’s two different railway track gauges - the SGR and Meter Gauge Railway (MGR).

Many of these structures are box culverts embedded in or through railway embankments, which serve as enclosed tunnels that channel natural streams, seasonal rivers, and storm runoff safely from one side of the tracks to the other.

Managing water flow prevents flooding that would wash away the soil foundation supporting the heavy train tracks along the rail line.

The casings can also be found on elevated bridge sections. Civil engineers prefer the hollow design because it offers resistance to torsion, which allows railway bridges to bear the massive, shifting weight of double-stack cargo and high-speed passenger trains without buckling or sagging.

Along sections that cross conservation areas, such as Nairobi National Park or the Tsavo ecosystem, the casings serve as safe underground corridors.

They allow migratory wildlife and local livestock to cross beneath the high-speed rail safely, avoiding deadly collisions.

Meanwhile, railway line network in the country is set to expand, with the National Land Commission (NLC) issuing a notice over the weekend for the compulsory acquisition of more than 300 land parcels for the Naivasha-Kisumu-Malaba Standard Gauge Railway (SGR) project. 

In a gazetted list dated September 10 and published on behalf of the Kenya Railways Corporation, the commission outlined additional parcels that would be affected by the planned Ksh700 billion project, as well as deletions and corrections to previous lists.

NLC has directed affected landowners and other persons with an interest in the listed properties to inspect the acquisition plans at its Nairobi offices or the Kisumu County Coordinator’s office.
