A really interesting view on how the railways helped to shape China - well presented and with a decent amount of information in English. And it’s free.

I am a railway enthusiast, and visit lots of railway museums. As noted by others: this one is for small exhibits, and the variety was excellent. Knowing the technology, I could cope with the lack of English captions. I was particularly interested in the maps, far better than any which I have found published or online. The museum is reached easily. It is not the original station building repurposed: it is a replica, built at 90 degrees to the original. For families, there is plenty of visual interest. It is particularly useful if you are caught by bleak cold or rain. I have also been to the locomotive museum, not accessed as easily. At both, most visitors were middle-class Chinese parents guiding their young children. Related is the aviation museum: even more remote, and harder to access. The supplementary questions are rather rigid. I would certainly recommend the museum as a must-do for railway enthusiasts on a first trip (and over 3 hours), but only as an option for general tourists (and 1-3 hours). It fits an all-day transit stop neatly. There is a shop selling railways items, notably models. IIRC it is accessible from the street directly. There are other museums of locomotives scattered around the country, but this is the only one with a comprehensive collection of small items.
