Mid October I returned to Switzerland and based myself at Olten. Here's the first day (Thursday 13th October), a couple of hours were spent at the station before going to my hotel room which has a handy viewpoint of the station.
Olten is a very busy station for freight, the majority of trains are mixed goods and mail trains. However you do get freight to/from the Lötschberg axis as well.
The hotel is called "Hotel Ameris" and is a clean comfortable hotel regardless of the view. (Yes I did request a railway view though!)
