Wayside equipment is installed both within stations and at different locations between them, making inspection and management labor-intensive. With the decline in maintenance staff, improving efficiency in equipment management has become essential. To address this issue, we developed a system that enables remote monitoring of trackside equipment using forward-facing train images captured by an onboard camera. The system estimates kilometrage, automatically detects equipment, and estimates deterioration of signalling equipment boxes. This paper presents the system overview, accuracy evaluation, and prospects for long-term deterioration monitoring.
