The locomotive for electric toy and model railways has a single-axle front bogie which can pivot about a vertical axis, one of the wheels of the front bogie being electrically insulated relative to the wheel axle, on which a substantially Z-shaped angular contact spring slides, on the upper leg of which, mounted on the support of the front bogie, a power pick-up pin slides which is mounted on the chassis of the locomotive.
