Fantastic images! You've done a really great job.
I love telephoto lenses for their ability to superimpose objects on top of others.
I love that about telephoto lenses as well. It works beautifully in industrial and railway photography in particular!
The industrial area of Cherepovets to the northwest of it is quite something. If I recall correctly, the district along the railway is covers a distance of about 10 km or even more. It reminds me of Tarkovski's masterpiece Stalker.
For example, check out this old post of mine for railway shots with a 300 mm lens:
