Hello Brian,
this is not a BLS loco, this is the SBB Ae 3/6 III No. 10262 (Swiss Federal Railways).
Best Greetings
Armin

Hello Brian,

welcome to this place specialized on Swiss Trains.

Thanks a lot for those wonderful fotos depicting trains from past times. They look very exiting.

Cheers, Olli

This is a very rare picture, as these locomotived (Ae 3/6 III) did not usually work to Interlaken, which was normally served only by Ae 4/7 (or BLS engines). I am wondering whether the first coach is a special coach owned by a tourist train company. Greetings from Peter

Peter, a very interesting comment about a tourist train. We travelled as part of a package holiday organised through British Rail who my father worked with. I know we travelled by sleeper train. I cannot say when this particular photo was taken but IF it was our return train then it would be a sleeper bound for France and the English channel.
