For a start, it would turn it into a true metro, rather than high-capacity commuter rail.Alon Levyhttps://www.blogger.com/profile/12195377309045184452noreply@blogger.comtag:blogger.com,1999:blog-6609536178570975752.post-36434942166395707902009-10-20T15:01:14.610-07:002009-10-20T15:01:14.610-07:00WMATA is hobbled by short platforms, insufficient ...WMATA is hobbled by short platforms, insufficient car fleet and unreliable berthing of 8 car trains in stations.

It works well with lower frequencies(10 minute or higher), but it can seriously constrain capacity.Justinhttps://www.blogger.com/profile/17536532964936231120noreply@blogger.comtag:blogger.com,1999:blog-6609536178570975752.post-2263968359548430012009-10-20T06:45:28.761-07:002009-10-20T06:45:28.761-07:00I don't know if there is a correlation, but th...I don't know if there is a correlation, but there certainly are consequences.<br /><br />Case in point, take the post which I wrote about <a href="http://tracktwentynine.blogspot.com/2008/11/understanding-blue-line-reroute.html" rel="nofollow">WMATA maximum train capacity</a> (where the graphics come from). Development along the Orange Line in Arlington and Fairfax Counties has pushed demand for Metro above the capacity of the Orange Line. Despite operating at 4 minute headways, trains are packed. Additional service cannot be added without reducing Blue Line service.<br /><br />So in that regard, it makes sense to cluster development around lines with a high theoretical capacity. In the Metro System this includes the entire Red Line, the combined downtown trunk lines, the combined Blue/Yellow Arlandria segment, and the Green/Yellow Lines north of downtown (because the Yellow Line could run all the way to Greenbelt).<br /><br />Of course building a separated Blue Line or constructing some new inter-line connections could solve some of these issues.Matt'https://www.blogger.com/profile/15011703558247093148noreply@blogger.com
