Why does it take so long to mend an escalator? Incisive article which seems to be metaphorically demonstrating the difficulties in repairing society's ills through the voices of mechanical engineering. "The chinks in an escalator's armour are the spaces between step and step, step and wall, and comb plate and step. That is where a shoelace, a scarf, a child's finger or a foot can get caught - which is bad for travellers - and where small hard objects, dragged along and forced between cleats and comb plate, can chew up the aluminium steps, which is punishing for the machine."
