Abstract
The advent of private railroad corporations presented many problems on administration's effectiveness. These brought an effect on safety management too. Most public railroad corporations maintain their rolling stocks and facilities by their own workers. On the other hand, private railroad corporations depend on outsourcing to cut down the cost of maintenance. But they have similar safety management systems. Therefore we investigated the gap between the two types of corporations, focusing on workers' safety attitude and proposed solutions to improve safety management systems in private railroad corporations.
