... that the Nanjing Metro system in Nanjing, China has a total of 139 stations, with transfer stations counted once for every line they serve? Source: Calculated in the article. Each line has a source detailing (in Chinese, but should be easy to spot if you can read numbers) the number of stations. They are added together per WP:CK as a "mathematical truism".
Overall: Sufficient prose, neutral if boring. Unsourced lines are all statistics that can be calculated from sourced parts of the article. "with transfer stations counted once for every line they serve" is not exactly interesting but is acceptable since accuracy is required. feminist (talk) 05:01, 25 January 2017 (UTC)
Thank you @Feminist: for your review! While I see that you've already approved it, I agree that my hook is a little bland, so what about this alternate:
ALT1"...that Sanshanjie Station in 1992 became the first Nanjing Metrostation to begin construction, eight years before construction commenced on the full system? Source: Ref and source in lead, relevant section in source: 1992年，南京市结合中山南路南下工程，开始建设地铁试验站——三山街站...地铁一号线才得以在2000年12月12日正式开工 --haha169 (talk) 15:58, 25 January 2017 (UTC)
I'm afraid the new hook would be unacceptable. I can understand Chinese, but the article does not mention the 2000 construction commencement. feminist 16:12, 25 January 2017 (UTC)
@Feminist: Yes it does, the second part of what I quoted above in the source clearly says how construction commenced in 2000: 地铁一号线才得以在2000年12月12日正式开工 --haha169 (talk) 16:31, 25 January 2017 (UTC)
I see what you mean, I will make this fact more clear in the article. Thank you for taking the time to review! --haha169 (talk) 03:28, 26 January 2017 (UTC)

OK, now I see it, List of Nanjing Metro stations does mention this fact, albeit in a roundabout way. feminist 02:25, 26 January 2017 (UTC)
