By October 2019, Pavel Chilin had constructed 330 meters of 300mm railway tracks, which took him 11 years. Today, we can see a railway with 10 sets of points, a turntable, and an 8-meter-long rail bridge. /VCG Photo

"When I was about 10 to 11 years old, I saw a narrow gauge steam train in Lithuania. And since then, I've have dreamed that I would one day have my own narrow gauge steam train," Pavel said. /VCG Photo
