Squeezed between sheer rust-and-ochre limestone walls with snow-capped Alpine peaks soaring beyond, a steam locomotive and its passenger coaches navigate the famous Brünig gorge at the summit pass height — a hand-tinted chromolithograph that perfectly captures the vertiginous drama that made the Brünig Railway one of Switzerland's great tourist spectacles at the turn of the twentieth century. Photographed from above and ahead, the locomotive pushes a plume of white steam upward into the narrow sky as the rack-and-pinion mechanism hauls the train through the tightest section of the Brünig-Schlucht, the rocky walls so close that passengers could reach out and touch them. This composition differs subtly from the Brennenstuhl series in its more painterly color saturation and the undivided back's trilingual legend — "Côté réservé à l'adresse / Nur für die Adresse / Lato riservato all'indirizzo" — marking it as Swiss-produced for a multilingual market in the pre-1904 UDB era. Collectors drawn to Alpine railways, Swiss topography, and early chromolithographic printing will find this a particularly fine example of the genre.
