An FIR has been filed against Aspee Sales Corporation, a Kolkata-based supplier of railway equipment, following a fire incident on the Mumbai-Firozpur Punjab Mail on March 7. The police allege that the company supplied 325 Motor Protection Circuit Breakers (MPCB) that were counterfeit and expired, compromising passenger safety. The circuit breakers were procured for ₹4 lakh after winning an online tender in November 2025. During the incident, smoke was detected from one of the train's coaches, and the MPCB failed to trip despite a high-voltage current, which could have prevented the fire. An inquiry revealed that the original manufacturer denied any authorization of Aspee Sales Corporation as a dealer and confirmed that the products supplied were indeed expired. The railway authorities have raised serious concerns over public safety due to the defective equipment provided by the supplier. Consequently, police have registered a case under sections 318(4) (cheating and dishonestly inducing delivery of property) and 125 (acts endangering human life or personal safety of others) of the Bharatiya Nyaya Sanhita, highlighting the gravity of the situation.
