Task: Explanation
Input (English): The Rhaetian Railway (German: "Rhätische Bahn" , Italian: "Ferrovia Retica" , Romansh: "Viafier Retica" ), abbreviated RhB, is a Swiss transport company that owns the largest network of all private railway operators in Switzerland. The RhB operates all the railway lines of the Swiss Canton of Graubünden/Grisons, except for the line from Sargans to the cantonal capital, Chur, which are operated by the Swiss Federal Railways (SBB CFF FFS), and the line from Disentis/Mustér to the Oberalp Pass, and further on to Andermatt, Uri, which is operated by Matterhorn Gotthard Bahn (MGB). Inaugurated in 1888 and expanded from 1896 onwards in various sections, the RhB network is located almost entirely within Graubünden, with one station across the Italian border at Tirano. Question: Are the Panamá Viejo and Rhaetian Railway located in the same country? Answer: no
