I don't know the difference between a llama and an alpaca but whatever the animals watching Ge4/4I No. 610 pass were, they certainly weren't native to Switzerland. On the other hand, 610 has been serving the Swiss people for well over 50 years and was photographed leaving Bever on train 1940 from Pontresina to Scuol-Tarasp on 8 January 2009.
