When I was 5 years old, I used to spend most of the time at a kindergarden or my grand parents' home- because my parents both had a full-time job. A full weekend with my parents was something that was worth waiting for a whole week. Being a serious railroad enthusiast at the time, my mom took me to the railway museum, literally every weekends.
I remember walking around the same corridor. Nothing has much changed here ever since it was built in the late 80s. It seems that there has been a little bit of update for exhibits related to the high speed train, but the place, overall, was same as if the time was frozen.
