River King Mine Train is a steel mine train roller coaster at Six Flags St. Louis in Eureka, Missouri. Built in 1971, it was the park's first coaster and opened with the park on June 5, 1971. The actual ride itself is one of two tracks, one which was later sold. Today, the ride operates with its original name. The ride has also received modern upgrades, including a new control panel. It is a popular family and beginner coaster, since it is the smallest in the park. Often called simply the Mine Train, it is unique in the fact that it has no automatic system for the lap bars; instead, employees have to manually lock and unlock the bars. Trains are five cars with riders arranged two across in three rows. In total, the coaster has three trains that have a total capacity of 90 riders (30 each).
