Which term provides power during outages for limited trips?

Explanation:
The idea being tested is having an on-board energy reserve that keeps the escalator running briefly when the main power fails. A battery backup provides exactly this: it stores electrical energy and releases it to the drive motor and essential controls during an outage, allowing a limited number of trips or a safe move to a stop so passengers can evacuate. The other terms don’t describe this emergency-energy capability—track/rail measurement is about alignment checks, installation sequence is about how to set things up, and a power source is a general supply not specifically the on-board emergency energy storage.
