What a fabulous idea for Meccano engineers to catch on to -super- efficient steam power to drive off gears, chains and pulleys! Working on methylated spirits and water, the Meccano Steam Engine has a single lever that operates the fy-wheel in forward and reverse directions, and also controls the running speed.
Clean, safe, simple to operate.

In the 1970s and 1980s, Mamod made the steam engines for Meccano. Read more about the history of Meccano here.
