I was looking through a PDF document I got from WMATA (10-Year Capital Improvement Program) and discovered WMATA will Reconfiguration the routing of some Blue line trains along the Yellow line (E, F and L routes) to accommodate the new trains coming from the proposed Tyson, Dulles, Loudoun County Silver Line M Route branch.
The same document shows 7% of trains will be 8 cars upon putting 48 of the Alstrom built cars in service by 2005;
2 Red line trains
1 Blue line trains
2 Orange Line trains
After all 122 of the Alstrom built cars are put in service in 2006 34% of trains will be 8 cars;
9 Red line trains
3 Green line trains
5 Yellow line trains
3 Blue line trains Reconfigured routing
11 Orange Line trains
3 Blue line trains
In 2013 when the 130 7000 series are put in service more trains will be 8 cars still being 34% of total number of trains;
18 Red line trains
8 Green line trains
7 Yellow line trains
3 Blue line trains Reconfigured routing
15 Orange Line trains
5 Blue line trains
