Field railway diesel locomotive Gmeinder 15/18 in closed design with a functioning headlight and two brick transport wagons, eight curved tracks with a radius of 115 mm, one straight track, and one connection track each measuring 133.2 mm. Includes a battery box with a switch (Forward/Reverse/Stop). The field railway tracks feature an integrated metal insert to increase the pressure of the wheels on the rails. This ensures a secure connection and high traction for a smooth ride. The track oval requires approximately 265 x 375 mm of space. To operate the railway, two 1.5 V Mignon batteries LR6/AA are needed (not included) or a power supply with 3 V direct current. Since the locomotives have minimal power consumption, the batteries or rechargeable batteries last a long time.
