Brujitas (in Columbia) are old motorcycles mounted to wooden platforms with benches, pushing those along abandoned railroad tracks for tourists to get a look at the rainforest/jungle

San Cipriano, Columbia, is located several miles within the jungle. 

Brujitas were invented out of necessity to move people and goods between San Cipriano and the other towns such as Zaragosa, on the railway that are adjacent to the highway

There are about 5 dozen men making a living from giving tourists these rail tours
