how were cable cars/ ropeways built in the Alps? How was all the construction material transported to the top of the mountain?

They first build a short one and use it to bring up the materials for a slightly longer one. Once the slightly longer one is built, they dismantle the shorter one and use the longer one to bring up the materials for the next, even more slightly longer one. So on and so forth. Its actually quite brilliant.
