<p>Rapid charging to a power storage element while an electric car is in a stopped state is stably and safely performed in an electric railway system. In an electric railway system having a power supply device for supplying power to an electric car (10), the power supply device comprises a power source (70) and an aerial conductor portion (1A) connected to the power source (70). The electric car (10) comprises a power collector (2A) which is provided on the roof of the electric car (10), which has a contact conductor portion (60) which can be in contact with the aerial conductor portion (1A), and which can raise and lower the contact conductor portion (60) based on an order from the outside, a switching portion (11) which is connected to the power collector (2A) and which makes and breaks a main circuit, a power conversion device (12) which is connected to the switching portion (11) and converts power, a power storage device (13) connected to the power conversion device (12), an electronic motor (16) which is driven by the power conversion device (12) and drives the electric car (10), and a control unit (15) for controlling at least the switching portion (11).</p> |
