PROBLEM TO BE SOLVED: To provide a train detection device of a railway crossing, which optimizes a construction range of rail plating for enabling secure detection of approaching and separation of a train at a railway crossing while optimizing cost efficiency of the rail plating.SOLUTION: A train detection device of a railway crossing, includes: first rail plating applied on a first section corresponding to a start point of the railway crossing of a rail; and a first detector for detecting at least one of a warning start and a completion of operation at the railway crossing. The first detector measures a start point short-circuit time as a conduction time between the first rail plating and a wheel of a train. The start point short-circuit time is a first predetermined value or more. The first predetermined value is based on a necessary time for operation of the first detector. A length of the first section is based on that the start point short-circuit time is the first predetermined value or more.SELECTED DRAWING: Figure 2
