Sinkhole Forces Closure of Zambia’s Ndola-Sakania Railway Line
Zambia Railways Limited (ZRL) has announced the immediate closure of the Ndola–Sakania railway line, a critical route connecting Zambia to the Democratic Republic of Congo (DRC), following a sinkhole incident that occurred on February 11, 2025. This decision was made to prioritize the safety of passengers, cargo, and surrounding communities.
According to ZRL, the sinkhole, measuring approximately 20 metres in diameter and 15 metres in depth, developed just six metres away from the railway line. Additionally, cracks have been observed as far as 20 metres from the sinkhole, with some crossing the railway tracks. These findings have raised serious concerns about the stability of the ground and the integrity of the railway infrastructure, prompting the closure as a precautionary measure [[1]](https://zambianobserver.com/zambia-railway-closes-ndola-sakania-line-after-sinkhole-threatens-safety/).
Initial investigations suggest that the affected area may sit on a limestone aquifer, a geological formation prone to sinkhole development. Experts warn that further ground movement could lead to additional sinkholes, posing significant risks to train operations and nearby communities. The closure has disrupted cross-border rail transportation between Zambia and the DRC, impacting businesses reliant on this vital trade route.
ZRL is working closely with key stakeholders, including the Disaster Management and Mitigation Unit (DMMU) and the Ministry of Transport and Logistics, to address the situation. Efforts are underway to assess the extent of the damage and develop a coordinated response to restore operations safely. The railway company has assured the public that safety remains its top priority during this challenging period.
The Ndola–Sakania railway line is a crucial part of Zambia’s rail network, which spans nearly 1,200 km and connects major economic hubs, including the Copperbelt region, to neighboring countries. This incident highlights the importance of maintaining and upgrading infrastructure to ensure the reliability of cross-border transportation, which is vital for regional trade and economic growth (https://zrl.com.zm/rail-network/).
For African travel and logistics professionals, this development underscores the need for contingency planning and alternative transport solutions to mitigate disruptions in the supply chain. As ZRL and its partners work to resolve the issue, stakeholders are encouraged to stay informed about updates and potential timelines for the reopening of the railway line.
