I have a few of these as well
. In summer (2009):
Ospizio Bernina, the highest station on the line.
The spiral viaduct at Brusio, where the line passes over itself.
Le Prese, where the trains use the street, like a tram.
And in winter (2011, with new trains having replaced most of the older ones):
In Ospizio Bernina again, with some 3 metres of snow.
En route in Cadera, crossing a historic motor car in splendid condition.
And finally, Pontresina, one of the most important stations along the line, where a motor car departs for St. Moritz with a snowplough.
