Remember, 4 [[File:icon passengers.png|16px]] at level 4 building works (and also [[File:icon waste.png|16px|link=Garbage]]) will be generated only if both the [[City Upgrades#Luxury|'''only when electrified<span style="color:#408">Luxury extension</span>''' ]] and the building itself are electrified [[File:e_energy.png|16px]].<br/>If you disconnect the electricity after the high rise building is built, it will stay as high rise. But , but it will become abandoned building. <br/><br/>

Not only does it look like after Zombie Apocalypse, but there will be no passengers [[File:icon passengers.png|16px]] (nor waste [[File:icon waste.png|16px|link=Garbage]]) generated until you bring the electricity [[File:e_energy.png|16px]] back.
