An X post with almost 500 thousand impressions has been circulating that claims an entire train station has been built in China from the ground up within 9 hours. The post includes before and after images that appear to depict a large train station with multiple tracks and large station building. 
The original post has been shared widely, with posters from around the world bemoaning their own country’s infrastructure and construction capabilities. This post has also been used in discussions about manufacturing in the wake of tariffs levied by the United States against China and other trade partners. We have noticed videos of China’s manufacturing capabilities, in particular, being circulated on English-language social media.
We attempted to search for recent announcements about a train station being built in China, but instead found reports and social media posts from 2018 with details about a project in Longyan City, China, that seem to match the claim post. These posts often include a timelapse video that shows train tracks being installed overnight. 
It appears, then, that at least part of the claim posts is inaccurate as it frames the 9-hour build as a recent occurrence and a “breaking” headline. However, was a train station actually built from the ground up?
While some English language reports from 2018 do frame the story as a “station built in 9 hours,” we also carried out a search for Chinese-language or China-based reports. The reports we found actually show that although a 9-hour construction project was carried out by 1500 workers, a large train station was not built from ground up.
Instead, articles from local news platforms describe a renovation of the existing Longyan Station which connected three rail lines to a new high-speed line. While a large number of tracks were laid as part of what some reports describe as an impressive “complex rail project,” no major work appears to have been done to station building.
Therefore, while details about the timeframe and number of workers appears to be accurate, it is not true that an entire large train station was built from scratch overnight. We give this claim a rating of false.
Confusion and inaccurate facts about this particular case seem to stem from English-language media misinterpreting the Chinese-language sources. Articles from platforms such as The Independent and even the South China Morning Post ran headlines that seemed to suggest an entire railway station was built. 
We found that the same claim was made and debunked in 2018 but nevertheless pops up regularly on social media despite being fact-checked. In this case, it has been used as part of ongoing discourse about manufacturing and efficiency, with the same misinformation being spread further to new audiences each time.
