Interlocking tower and rail bus 162 in 25 de Agosto. AFE got several of this rail buses around 1980 from German Railway (Deutsche Bundesbahn, ex VT 95), today only this one is operational.
Switcher 162 is working in a very crowded situation as three (!) Bernina Expresses are present at the small Tirano RhB station just across the Swiss-Italian border. (www.treinen-foto.nl)
