Mancha 1,5ton Trammer
This is a battery locomotive, meant to be used to haul ore cars out of the mines, it''s small being just 1,5ton, and runs on just 18" gauge (ca 45,72cm) but according to the drawing I used (found in the NGSLG Sep/Oct 2000 edition, page 88) it''s the most popular sized models in the mining industry.
