I travel quite often between the Uppsala and the Swedish capital stockholm part stuvsta with SL commuter trains. It happens quite often now-a-days that escalators are out of order for various reasons. We passengers are therefore forced to go up and down the stationary escalators.
there are no stairs as an alternative? It is very difficult to go in a stationary escalator, especially with a heavy bag on his back.
If an evacuation would need to be done can't all queue up for the few elevators that are available in the vicinity.
the building entrances without stairs? Such does not need to be turned off.
