A high-speed transportation system comprises an evacuated travel conduit divided by closable gates into a plurality of segments associated with corresponding segment pumps that maintain operating vacuums within the segments when vehicles are present. When a segment is unoccupied, energy is saved by closing the adjoining gates and deactivating the associated segment pump, thereby deactivating the segment and allowing the segment's internal pressure to rise due to leakage. As a vehicle approaches, the segment pump is reactivated, lowering the internal pressure to the operating vacuum, and the gates are opened. Embodiments include a boom-tank system that can accelerate re-evacuation of a segment having an increased internal pressure by establishing fluid communication with at least one recently deactivated segment having a lower internal pressure. As a vehicle transits the conduit, a rolling, contiguous group of activated segments surrounding and in advance of the vehicle can be maintained.
