Several times each week, Dr. KC sets out on the "bamboo train" to visit rural areas not accessible by road. The "bamboo train" runs on narrow gauge tracks built by the French in the 1920's. Since removing land mines placed along the tracks by the Khmer Rouge, local residents have built dozens of miniature "trains". These "trains" consist of bamboo platforms attached to old tank axles, powered by small motorcycle engines. For little more than $2, KC loads up his equipment and his local staff people and sets out on a mission.
