PROBLEM TO BE SOLVED: To provide an overlap structure in consideration of spatial arrangement of a line A and a line B so that a contact angle between a pantograph and a trolley line can be made small at a transition point from the line A to the line B.SOLUTION: Near an entrance F of an overlap section R, a contact fitting 10 between a line B 7B and a substitute trolley line 9 is arranged laterally outside a moving range of a pantograph P, more specifically, in a position distant by a half (900 mm, for example) or more of the length in a width (rail orthogonal direction (lateral direction) in a horizontal plane) of the pantograph from the rail lateral center. In the position, a line A 7A is located sufficiently distant from the line B 7B in a rail outward direction, thereby preventing the pantograph P receiving power from the line A 7A from coming into contact with the contact fitting 10 of the line B 7B. In the entrance F of the overlap section, the line A 7A and the line B 7B are separated from each other only by 150 mm in a height direction, thereby reducing the height of the line B 7B. |
