We also visited the cathedral while we were in Olomouc, and the highlight of this was a demonstration of the late-19th Century electric pipe organ (with the original knob and tube wiring). Many people disliked the ornamentation of buildings, churches, organs, and so on during the 19th Century, but in hindsight industrial-era engineering combined with pre-industrial taste produced a much better result, I think, than anything has since.

This tunnel, not original, but made out of a pipe found somewhere, is part of a park that used to be a railway freight yard. The tour guide said the yard was originally called Rangierbahnhof Tempelhof, although all the signs I saw said Bruckenmeisterei, so whichever one it is. Much of the infrastructure, all of it steam-era, is still intact, as the yard was in control of the Soviets (as was all of the rail infrastructure in Berlin) after World War II, and lacking adequate international traffic to keep it going, it was eventually abandoned, with almost everything sitting abandoned until 1989, when it became the park that it is now.
