My dad has one of these little steam engines.
When I was a kid my brothers and I would sometimes pester him to fire it up so we could watch it go. It was fueled by little blocks of some type of solid fuel made by a company called Esbit, and each of us wanted to be the one to light it off and slide the little tray under the boiler. The same type of fuel is still used to heat some types of small personal camping stoves. Back during WWII every German soldier was running around with one of them in his gear. Now seventy years later both the Esbit stove and fuel are still available, nearly identical to their 1940's counterparts.
