I might go for them just for the sake of exploring more of the stations (some currently not used). Normally I only get them if there's an achievement/trophy. Seeing as preserved routes have them, you would automatically get the core game collectible ones anyway.
Did the Bakerloo ones but feel like the Sand Patch ones are going to be a bit annoying to find. I will try to get them before we start seeing more preserved routes introduced.
I haven’t got the Sand Patch ones yet. Just Bakerloo and Koln>Aachen. The Sand Patch ones look pretty long winded with lots of walking involved.
My reward for searching out collectables in the Köln Schnellfahrstrecke turned out to be a lot of clever and well crafted scenery we would never see from the train. One of the best bits that should not be missed is the Rur river, a short walk from Düren, that we normally pass at 100kph.
I liked the Donkeys in place of Horses on the plinths between Köln Hauptbahnhof and Hohenzollernbrüke.
Perhaps they didn't get a license to replicate the authentic statues which can be seen e.g. on google streetview.
