610 and 603 approached Celerina with RE1125, the 08:58 from Chur to St.Moritz, as the snow fell on 5 March 2012. The pair had taken over from a Ge4/4iii at Samedan.
The short trip from Samedan to St.Moritz with this train had been a regular Ge4/4i duty the previous winter but by March 2012 it was a rare occurance and a pair was very rare indeed.
