OK, "distributed power", passenger style! I didn't think they could pull 100 coaches up that grade, simply because the couplers wouldn't take the stress.
For those who aren't familiar with this line, it's one of the crookedest railroads in the world. It isn't far from Berguen to Preda, straight line, but the track crosses itself in at least four places, and there are three spiral tunnels, including two stacked on top of each other. It looks like a "spaghetti bowl" model railroad.
