The Gornergratbahn Bhe 4/4 3062 seen between Zermatt and Findelbach

Originally Rowan-type trains (locomotive with a half-on leaning trailer) were travelling the line with a catenary of 550 V / 40 Hz and no winter traffic. For the first time the galleries were extended and snow was cleared in 1928 to provide an all-year-long traffic on the line. It was favourably accepted and additional snow control was needed later on.
