Data from reprint of SA Saint-Leonard data sheet for Serie CI (1898), 1903 Saint-Leonard Catalogue. Works numbers were 1160-1165 in 1898.
A small, narrow-gauge railway typically needs very small locomotives and this Belgian builder supplied a suitable sextet. Equipped with the mimimum, the engines sported large, vase-shaped spark-arresting stacks to reduce the danger of line-side fires from buring wood.
