This flywheel drive mechanism is described in the "Shuttle Loop" patent of 1978 , too !!!

Some things have been changed , but here is a part of the original patent-script :

A motor (44) is linked via a belt  (45) and a slipping clutch (46) with a flywheel (47) . The flywheel is connected to a air operated clutch (48) and a gearbox (49) , which works as a speed reducer , to the shaft of the front rope-pulley (9) . A programmer (50) controls the clutch (48) associated with the front rope-pulley as well as the brake (42) and an ancillary motor (43) which are both coupled with the rear rope-pulley . When the carriage or "pusher" (6) is positioned behind the train the programmer deactivates the station brake (38) and activates the clutch (48) to couple the continously rotating flywheel with the front rope-pulley , whereby the carriage and of course the train are getting acceleration . The clutch (46) slips when the flywheel loses speed to 872 rpm during this operation . A speed   sensor releases the clutch at this point . After the clutch (48) is deactivated , the conveyor (7-9) continues running by inertia until it is stopped by a brake (42) with the carriage still spaced on its starting position . Note that there may be differences in getting the carriage back to the   station . Another possibility is to stop the conveyor after a start and move it in reverse right to the point where it   is needed for the next  launch . When the train has been arrested at the station , the brake (42) is released and the motor (43) is briefly energized to re-establish the launching position . By this time , the continously operating main drive motor (44) has restored the flywheel to its normal rotary speed

Corrections to the above as it relates to Greezed Lightnin'

1. There are no belt on the motor, it is a direct drive system since 1998.

2. The slip clutches are in the wrong place. The are on each side of the
bullwheel.

3. One of the speed reducers (gear boxes is in the wrong place)

4. There are not enough pedalster bearing displayed.

5. There is no oil pump displayed.

6. In order to launch the train the flywheel must be rotating at 860
revolution. It drops below 860 during the launch but the speed varies each
time. The direct drive system allows the flywheel to obtain correct launch
speed faster.
