It is absolutely open.
Have been there twice in the past two months.
It is however difficult to find, tucked in the left corner of the (old) main entrance’s portico. (The “front” of the building.) You may even have to slip between a barrier to get in there.
It is none the less well frequented and has some really very interesting collections of everything from maps to equipment to books to artwork/ signage; relics of the near past of railways and stations.
It feels that it was made by SRT workers for SRT workers, which is actually really unique and cool.
Use the camera function on the Google Translate app for some placards if you get stuck.
