In Camlica that is within easy reach by dolmuş (you might even walk the distance, as I once did) is a train museum that has some great steam locomotives and various other titbits of rail life on display.
In 2018 I scanned the slides that I used for an earlier version of the pictures (they were often too saturated) again, and after editing I overwrote the earlier versions with more realistic versions. Note that I particularly photographed details, as I was more interested in the compositions than in the machines per se.
