  Background and a ims: Subway system including infrastructure systems in the transportation industry can potentially exposed to fire, flood, earthquake and similar events and could create catastrophic losses to society. Therefore, this study aims to assess the risk of fire in Tehran subway stations (line 1).

  Methods: Inperforming this research, after the identifying the fire hazard resources in subway stations through observing, interviewing techniques and reviewing the documents, using fault tree analysis the causes of electrical fires in rectifier substations in line 1 of Tehran metro, was determined.Furthermore, with quantitative fault tree analysis, the probability of the fire risk was calculated per year.

  Results: Our findings indicate that, main causes of electrical fires in this post are including signs and devices, improper maintenance, improper implementation during equipment installation, inappropriate quality of equipment and their aging. The probability of accidents was calculated as one accident per every 11 years.

  Conclusion: Byholding training courses for personnel involved and careful monitoring during maintenance and installation of equipment, much lower probability risk would occur.
