There is a big bonus to traveling by train. You have to wait at train stations and often need to take a tunnel or two to get where you want to be. Both subjects are photographically interesting as they naturally offer leading lines. And of course one is often not waiting alone, people of all sorts and breeds do the same. Offering heaps of opportunities for some people/street photography. As the station is almost never the end destination, the walk to or from there can also give some opportunities. Like, in this case, some architecture I spotted during a short walk to Audi Forum Neckarsulm where I was headed for an assignment.
