The article contains several stubby one- and two-sentence paragraphs that should be combined. In addition, there are several awkward sentences and phrases such as "It was the system's first in-fill station (a new station between existing stations).", "There it enters a tunnel and curves west to Rockville Pike at White Flint.", "The line runs in this manner northwest across the District-Maryland line,", and The station list would also appear better in table format.
Large sections of the history are unreferenced as is the chronology table and station list. The sentence "There is a maintenance yard between the Florida Avenue and Rhode Island Avenue stops." also needs a citation.
It is broad in its coverage.
a (major aspects): b (focused):
A section detailing the services along the line should be added to the articles. In addition, the lead does not adequately summarize the contents of the article.
The article does have an image, so it passes this criteria. However, there are more images on Commons that could be added to this article.
Overall:
Pass/Fail:
The article currently has several issues before it can be promoted to GA. Therefore, I will have to fail it. The article may be renominated once these issues are fixed. Dough487204:29, 11 December 2010 (UTC)[reply]
