The Dahlonega Mine Train is a steel roller coaster located at Six Flags Over Georgia in Austell, Georgia, west of downtown Atlanta, Georgia. The ride has three lift hills with brief elements between each that wind through a wooded, hilly landscape. This is a family coaster that is named after Dahlonega, Georgia, a village in northern Georgia that was a center of the gold rush of 1828, the first gold rush in the United States of America. ==Operational information== When opened in 1967, the Dahlonega Mine Train had the capability to run four trains at once, the reason for its high capacity. In the mid-1990s, however, the O. D. Hopkins Company rebuilt and refurbished the ride, replacing some wooden supports with steel, supplying new track, and a fully computerized control system. This new system is not capable of running four trains at once (three is the current maximum number of trains during normal operation). Thus, the stated capacity of 2200 riders per hour is inaccurate. With three trains, the capacity is 1300 riders per hour, with two trains it is 800 riders per hour, and with one train it is 500 riders per hour. Four trains can be run at one time, but the likelihood is low considering a full-time Rides Department supervisor must be present. As with most modern roller coasters, a block system keeps trainsets moving and prevents trains from colliding with each other. Rarely, trains will "roll back" into the tunnel from the end of the station platform. The control program is set up to handle this problem so that another train cannot collide with the stalled train. When this happens, guests are unloaded in the tunnel (which has lights and a stairway for such an event) and a winch pulls the empty train back into the station. Trains feature a single lapbar in each row actuated by depressing a foot pedal near the front of each car, done by a station attendant. Unlike many roller coasters, though, there are no upstop wheels to prevent the trains from leaving the track; instead there is only a flange (upstop pad) which achieves the same result. This is common on "mine train" type roller coasters. The ride begins with the train leaving the station and turning left into the transfer track area. From there, it climbs the first lift. After clearing the lift, the train turns right and enters the "figure 8" area of the track. After that, it rides through the "b" dips. Next, it climbs the second lift, and turns left into the "mini horseshoe", which leads into the spiral. From the spiral, it rides over the "c" dip and climbs the third lift. After clearing the third, and final lift, it turns left into the "big horsehoe" and descends into the tunnel, reaching its actual top speed of 35 mph. From there it pops back above ground and slowly enters back into the station. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dahlonega Mine Train」の詳細全文を読む スポンサード リンク
