to "Track A" to receive the next incoming cage. Then "Traveler B," its cage having been emptied and refilled, as indicated by the arrows, passes over to "Track B," and its content starts back across the structure. Finally "Traveler B"" moves over to "Track A" to receive another incoming cage, "Traveler A" having meanwhile received an incoming cage and moved over to "Pocket A." This completes a cycle of traveler operations at the left end.

At the other end, the first returning cage enters "Traveler A'," which immediately moves into "Pocket A'," where the car, vehicles, and pedestrians pass out to the left, as indicated by the arrow adjacent to the center-line of street-railway track; then the re-loading is done from the right, as indicated by the other arrow. Meanwhile, "Traveler B' " has moved to "Track B," received the second cage, and carried it to "Pocket B'," where it is unloaded to the left and reloaded from the right, as shown by the arrows. After the cage in "Traveler A' " is reloaded, the said traveler moves over to "Track A" and lets the cage pass out for another trip. Then "Traveler A' " moves over to "Track B" to receive the third cage, which it takes to "Pocket A'," and "Traveler B' " with its reloaded cage passes to "Track A" to discharge its contents. This completes a cycle of traveler operations at the right end.

As the rush traffic of the morning and evening hours is reduced, one or more cages can be run to the storage pockets, where they can be lubricated, cleaned, and put into good order; and at night a single cage can be operated by filling all four of the storage pockets and one of the other pockets with cages.

It will be noticed that while the automobiles and the other vehicles always head in the same direction, they do not have to back out of the cages. It would be practicable to let the said vehicles head in either direction by putting a double track on each cage and turning the cars and other vehicles out quickly to the right on the approaches. This would necessitate enclosing in a "corral" all incoming vehicles until the cage is emptied. There does not appear to be much choice between these two methods of operation.

Fig. 32a indicates the method of caring for pedestrians. They pass up the stairways shown at the ends to covered platforms alongside the storage pockets, where they await the arrival of the cage; and they would not be allowed to enter the latter until after its incoming load of pedestrians had passed off by the adjacent exit-stairway. There could, therefore, be no clashing of incoming and outgoing pedestrians; and the approaches to the entering stairway could be arranged so as to avoid any interference between the pedestrians and vehicles of all kinds.

Assuming a maximum attainable velocity of thirty miles per hour, which may not always have to be utilized, and with only four cages and two travelers operating, the following time schedule was figured, based upon an allowance of three minutes for a cage to cross the river:
