The original German caption of the graph in the cited publication reads "Abb. 292. Reußbrücke bei Inschi." which translates to "fig. 292. Reuss Bridge near Intschi"
No scale or legend was provided with the drawing. The spans of the embankments, the free width under the beam, the height of the beam and the distance from the surface of the Reuss river at low water to the top of the rails are indicated in [m] as well as the incline of the route in [‰]. The Reuss is labeled as Reuß.

The part of the Gotthardbahn article referring to the Intschi-Reuss-Bridge in German: Die Gesamtzahl der Brücken und Durchlässe beträgt 1234, deren Gesamtweite 6471 m. (...) die größte Lichtweite eines Trägerfeldes 75 m (Inschi-Reußbrücke nachträglich verstärkt) (Abb. 292). (...) Brücken mit eisernem Überbau sind auf der Gotthardbahn sehr zahlreich; die Eisenbauten haben ein Gesamtgewicht von 17.723 t, sind sehr einfach und mit wenigen Ausnahmen geradlinig begrenzt. (...) Von größeren Bauwerken mit geraden Trägern sind zu erwähnen: (...) - die Reußbrücke bei Intschi mit einer Öffnung von 75 m Weite, Schienenhöhe 76 m über dem Fluß (Abb. 292); (...) in Englisch The Gotthardbahn and its branchlines pass over a total of 1234 bridges and open passages which span a total length of 6471 [m]. (...) the largest width of a beam structure is 75 [m] (in case of the subsequently reinforced Intschi-Reuss-Bridge) (Abb. 292.) (...) Bridges with iron superstructures are very frequent on the Gotthard line and their iron structures weigh 17723 tons in total. (...) The following of the larger structures are worth mentioning: (...) - the Reuss Bridge near Intschi with an opening of 75 [m] clear width, rails 76 [m] above the river (Abb. 292). end of translation

Note that in the article the names "Reuß" and "Inschi" are used which are partly still in use today where "Reuss" and "Intschi" seem to be the more frequently used names today. In the following "Reuss" and "Intschi" will be used.

Intschi-Reuss-Bridge on the Gotthardbahn near Intschi.

Going up the northern ramp of the Gotthardbahn starting at Erstfeld, passing the Amsteg-Silenen station you pass the Chärstelenbach Bridge. Having passed the Bristen Tunnel you will cross the Intschi-Reuss-Brige onto the other side of the Reuss valley before passing the abondoned Intschi station and entering the Gurtnellen station.

The Intschi-Reuss-Bridge is one of many very simply constructed steal bridges using truss beam constructions with straight outlines. The bridge stands out because of its wide openings spanning 75 [m] and rails at 76 [m] above low water. Subsequently the bridge had to be strengthened with the fish-belly truss structures indicated in the illustration to account for increasing traffic and loads even before 1914, still during times of steam operation of the Gotthardbahn. With the Intschi-Reuss-Bridge like all the other iron bridges and their subsequent reinforcements being built to specifications based on traffic volumes and loads that were superseded again and again the iron superstructure of the bridge eventually had to be substituted with a modern one.

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 illustrations or whether he copied them from one of the books or periodicals listed or from elsewhere. Disregarding the listed business reports of the Gotthardbahn and its liquidation commission the most recent dated literature listed originates from 1895. Obviously all listed sources predate the publication of volume 5 of Röll's encyclopedia in 1914. Dietler lists the sources as follows below. Originals of the graph might be found there. With standard operation of the Gotthardbahn having started on 1 June 1882 the line was well established during the publication of of volume 5 of Röll's encyclopedia in 1915. The engineering drawing probably dates from somewhere between the final planning period and the time just before the last construction phase.
