Travellator

hanks once again to Andy G. for his great work on this project

To aid speedy access around the 1500 metre circumference of the station, a travellator has been added to run around the lower section. At 5kph, nowhere on the station is more than ten minutes away. At the spokes, users in the upper section have to descend by a lift or pair of elevators to the travellator deck. Lower section users have to ascend one flight to the travellator deck. In none-spoke lower zones, a simple platform can be used

to allow access to the travellators. The presence of this "el" makes zone space in the lower section slightly more valuable than that in the upper section.

At zone intersections, the travellator track is split to allow air-tight doors to shut, and newbies can often be seen being caught out by the break in the line. Both travellators and escalators (where they cross between airtight zones) are halted in the event of any serious pressure differential.

As designed, over 3000 people an hour can use the escalators, lifts and travellator systems. With a 24 work cycle, and therefore no real rush hour, usage of these facilities is generally "light". In a fully occupied station with a population of up to 20000, the facilities as fitted on La Salle would run at optimum capacities.
