NORMAL LIFTS
there is also a normal set of lifts which look dull compared to the paternoster but they are not dull because they are very fast (about 3.5 mps). sometimes it is quicker to get the paternoster sometimes it is quicker to get the normal lift depending on how far you are going and how long it takes the noram lift to arrive (most people get on the paternoster anyway because it is more fun)
