The original German caption of the graph in the cited publication was "Abb.90. Längenschnitt der Lötschbergbahn".

The author Dietler did not provide a copyright for the graphs used nor did he use specific citations within his article and listed sources as "literature" solely at the end of his chapter. It is not clear if he is the original author of any of the drawings or whether he copied them from one of the books or periodicals listed or from elsewhere. The most recent dated literature listed originates from 1904. Obviously all listed sources predate the publication of volume 2 of Röll's encyclopedia in 1912. Dietler lists the sources as follows below. Originals of the graph might be found there.
