On the way back from our Swiss holiday last year, we had to stop for a picnic. I chose a spot near Frick, where we could sit quietly in the shade and where I could set up my tripod with camera. Armed with a remote and sandwich, I could enjoy a family lunch while also shooting some trains.
The last train we saw was headed by SBB Cargo Shadowpiercer 193 665 which made the stop all that more worthwhile.
