This photo was always going to be tough but after a few of the others were identified in Switzerland I started to think this was part of the same series. Mainly because it seems to be taken from a train like others in Switzerland. The sideways blur in the photo giving it away. Photo 14
, Photo 27
and Photo 04
have this and were found on the train line from Zurich to Interlaken. Then a few of photos were identified in Interlaken itself so I knew Grandpa was in Interlaken and that he caught a train in Switzerland - starting or finishing in Interlaken West train station.
clearly has the station sign in it.
The biggest clue from the photo are the two bodies of water. One a man made canal, the other a seems like a river or stream. Because of the other photos found in this area, mainly Interlaken, I jumped straight to Interlaken on a map. And sure enough there was a man made, canal, right next to another body of water, just outside the train station Grandpa visited. I was excited and thought we might just find this one after all. I just had to get myself to Interlaken.
