The front cars are loaded to keep the weight distributed in the front of the train. Also, it keeps the ride ops from having to frequently buckle and unbuckle empty seats. The blue train has a lot of down time for the same reason. Gemini just doesn't have enough riders to keep the trains full and when this happens, we start eliminating seats and/or trains. Remember, at max. capacity Gemini can do over 3000 riders an hour. Finally, when there is a routine problem, the trains either stop on the lift, on the last turn, or in the brakes outside the station.
