This is my version of the Meccano battery locomotive with two wagons model 6.24 from a No. 6 set 1941 manual modified to run on O gauge and powered by a clockwork magic motor. The first part shows the locomotive with the two wagons and the second part shows the locomotive running faster and longer by itself. I have used only the parts that would have been available in the No. 6 set of that time. I am running the locomotive with just the pulley wheels, and surprisingly they stay on the track, as this set had no flanged wheels, available only in bigger sets. Due to the limitation of wheels I have used only two wheels in each wagon.
