The invention discloses an electric rail car capable of walking inwards and outwards. One piece of I-shaped steel is arranged below each rack; a supporting plate is horizontally arranged below the I-shaped steel; two bearing boxes are fixedly connected to the inner and outer sides of the upper end surface of the supporting plate; walking gears are fixedly connected to the end parts, extending outof the bearing box, of the driven shaft and the driving shaft; the walking gear is meshed with the rack; the output end of a speed reducer is in transmission connection with the driving shaft; limiting mechanisms are mounted on one sides, deviating from the centers of the protective plates, of I-shaped steel; the limiting mechanisms comprise a first limiting mechanism and a second limiting mechanism; the first limiting mechanism comprises a first limiting frame fixedly connected to the supporting plate and a first limiting wheel rotationally installed on the first limiting frame; the outer peripheral surface of the first limiting wheel is tightly attached to the vertical part of the I-shaped steel; the second limiting mechanism comprises a second limiting frame fixedly connected to the supporting plate and a second limiting wheel rotationally installed at the top end of the second limiting frame, and the second limiting wheel is tightly attached to the horizontal part of the upper sideof the I-shaped steel. The device has the advantages of being novel in structure and stable in movement.
