Sri Lanka's railway station masters union has warned of trade union action unless authorities resolve critical signalling problems affecting multiple railway lines, with trains currently operating under temporary safety measures.

The Sri Lanka Railway Station Masters' Association has escalated pressure on authorities by threatening industrial action if signalling faults across the railway network are not permanently addressed. Union Chairman Sumedha Somaratne stated that train services on the Talaimannar line resumed despite unresolved signal defects, creating what he characterized as unsafe operating conditions.

According to Somaratne, trains on the single-track section between Medawachchiya and Talaimannar Pier are being operated under a "pilotman system"—a method intended only for temporary use during signalling failures. The union contends this practice has now become a continuous operational measure despite the line's recent restart. Similarly, the Maho–Anuradhapura section continues to experience unresolved signal problems, with train movements occurring under temporary signalling arrangements.

The station masters have formally notified authorities in writing that trade union action will commence if permanent solutions are not implemented. Somaratne also highlighted concerns about deteriorating railway infrastructure, noting that lines recently reconstructed at significant public expense are facing degradation due to inadequate maintenance and operational improvements. The union's warning reflects broader frustrations within the railway system over what it views as insufficient investment in infrastructure repairs and safety measures.
