I previously shared how train documenting has become one of my favorite hobbies. At first glance, one might assume that this hobby is easy—simply grab a camera or smartphone, snap a picture or video as a train passes by, and the work is done. It sounds effortless, especially when compared to activities like traveling to famous national parks....

When people ask about my hobbies, and I respond with, "I like train filming," the reactions are often with a look of astonishment, as though I've just revealed a strange and quirky secret. It's not exactly the most common pastime, but for me, it holds a special significance, one deeply rooted in both nostalgia and newfound purpose.
