How to shorten lift queues and diagnose grey upgrades

Follow these steps

1. Read the bottleneck at the busiest station

   Select the lift and compare the queue, capacity per hour and average seats filled. Official notes say the lift panel exposes these throughput readouts. An empty chair leaving a long queue points you toward loading efficiency; a fully used small lift may need more physical capacity. Inspect the lift feeding the busiest hub, not only whichever queue is easiest to see.

2. Use a reachable queue and keep the exit clear

   Draw a lift queue from the station with a clear entrance and space around neighboring facilities. A community reply describes limiting waiting to a placed queue’s size. This can contain crowd spillover but does not add seats per hour. If Guests Can’t Board appears, fix the queue connection before making it longer.

3. Check lifties and Operations speed

   Look at efficiency on the lift’s first tab, then add a lifty only if the extra wage is justified by the loading improvement. Check the speed control under Operations and compare the capacity/dispatch readout after changing it. Follow the game’s available settings; do not assume extra staff or a higher speed will remove every queue. Promotion traits can also improve loading and dispatch.

4. Diagnose a grey upgrade in the right order

   Open the lift’s Upgrade list. If the desired type is locked, open Build → Lifts and check what your reputation has unlocked. If the type is available but the upgrade is still grey, read the station-space note and inspect room around the terminals. Do not spend cash elsewhere under the assumption that money is the only requirement.

   Check	What to do next
   Not unlocked	Use the available type until your reputation unlocks the desired lift.
   Insufficient station space	Read the warning and make room at the affected station before retrying.
   Insufficient cash	Recheck Upcoming bills before saving for or financing the upgrade.
   None of those explains it	Keep the save/build and the exact disabled-control message for a report.

5. Choose an upgrade or a second route based on where people wait

   If one small lift is saturated and its route is useful, an unlocked upgrade can be the next investment. If everyone must use the same lower lift to reach every extension, another upper lift can leave that lower bottleneck intact. Consider a separate reachable base lift with suitable runs to spread guests, and include its staff and trail-clearing cost in the decision.

6. Use price demand as a temporary pressure control

   At the ticket office, test a price increase while watching the demand multiplier and finances. The Part 2 example deliberately reduces demand when arrivals exceed capacity. Compare queue complaints and actual riders afterward; do not copy $99/$69 as a guaranteed optimum. Reassess after each capacity change and during different seasonal events.

What success looks like

The chosen lift is reachable and staffed, its efficiency and capacity explain the observed line, and your change increases served riders or reduces excess demand without leaving the next bill unfunded. A neat queue alone is not a capacity increase.

If it does not work

If queues return after an upgrade, check the new arrival level and other lifts feeding the same hub. The public example still reports long queues later despite several upgrades. If a grey option has no unlock, space or cash explanation, preserve the disabled state and build for a bug report rather than repeatedly buying adjacent infrastructure.
