I love trains, too. I do not what exactly I like about them but just playing, riding, or looking at trains give me tranquility in life. Although watching real trains pass by on a rail track is really noisy but it kind of gives me peace. It is like watching the sunset on a cook beach for me. I fell in love with them. I have been into them ever since I was a kid since my siblings were quite playing with them a lot, too.
