Despite appearances this is a railway, not tramway. This is the Bern Worb Bahnen, with trains at their own dedicated station in Bern. There are two routes to Worb from Bern and both were (and are) very busy, providing an excellent, clean and sustainable commuter service into Switzerland's capital. The other line is far more railway like and starts from a smart underground station under the main SBB station in Bern. Both lines are metre guage, like most Swiss light railways.
