Corporate fraud has transformed the UK-funded Railway City Project into a crime scene. New evidence shows that Kenya Railways Managing Director Philip Mainga and a network of state officials allegedly ran a multimillion-shilling bribery trap.
This high-level scam targeted the China Road and Bridge Corporation (CRBC), stealing their money under the false promise of a guaranteed government contract.

The Philip Mainga Bribery Chain
Investigations into the Sh30 billion Nairobi Railway City tender have revealed a clear path of corruption. Philip Mainga is the primary figure accused of collecting millions in bribes from Chinese officials.
Mainga and his group of intermediaries allegedly exploited their positions to entice the highest bidder to secure the contract. However, taking the money was just the beginning of the scam; the contract they provided was built on illegal shortcuts that could not survive a legal challenge.
A Fraudulent Tender Exposed in Court
The heist began to fall apart when the China Civil Engineering Construction Corporation (CCECC) noticed the game. CCECC had offered to do the work for Sh23 billion, saving Kenyan taxpayers Sh7 billion. Because they refused to play the bribery game, Philip Mainga and the evaluation team ignored their lower bid.
The Public Procurement Administrative Review Board (PPARB) has since stepped in and officially cancelled the award. The board found that the entire process led by Mainga was a fraud, designed to favor the company that paid the most under the table.
The Global Cost of Corruption
This is not just a local scandal; it is an international embarrassment. While Philip Mainga allegedly filled his pockets, he put the reputation of the entire country at risk. Bribery has now linked British firms like Atkins Global and the financial giants at KPMG to a tainted project.
For the Chinese investors at CRBC, the “facilitation fees” they paid to Mainga are gone. The Railway City project has stalled, leaving the Kenyan transport sector in shame.
Conclusion
The Railway Heist proves that corruption is the primary obstacle to Kenya’s growth. Philip Mainga stands at the center of a Sh30 billion wreckage that has wasted time, money, and international trust.
There is no room for “negotiated” tenders that bypass the law. As the 21-day re-evaluation period commences, it is evident that those who exploited a national project for personal gain are subject to the full weight of the law.
