Preservation’s transit ring wasn’t that big compared to the major Corporation Rim hubs. Or even to the non-major Corporation Rim hubs. It had only one entry/exit point for passengers, near the booking kiosks where you could search for berths on the docked transports offering passage. There was another entry/exit point for crews of private ships and cargo-only transports in the Merchant Docks, and Dead Lutran might have come in through that section, but it made more sense statistically to start at the public entrance.
