The water collected at the foot of the apparatus at the end of each trip was brought back to the top with a 25-horsepower pump—true horsepower, because the pump was powered by steam. Travel time was two minutes, but filling the upper tank took more than ten minutes, forcing waits between departures, in spite of often considerable crowds. The last adventure after the ascent was crossing the 100-meter footbridge up the steep slope. Built by Gustave Eiffel, the footbridge was only wide and very exposed to the mistral winds.
