PlanItMetro

The purpose of this strategy is to allow different rail lines to operate on the same track.  This type of operation can help reduce capacity constraint on some lines and provide new connections between existing Metrorail lines.

The four interline connections proposed include:

Some benefits of these interline connections include:

1. Orange/Silver-Blue inter-lining south of Rosslyn to allow a Silver Line running between the two airports
   1. BENEFIT: Faster trip to Ballston, Tysons and airports within Virginia
2. Blue-Yellow inter-lining north of Pentagon to allow I-66 corridor rail lines going through 14th Street Bridge
   1. BENEFIT: Utilize throughput capacity on 14th Street Bridge
3. Yellow-Green inter-lining south of L’Enfant Plaza to allow a Yellow Line split to Anacostia/Navy Yard
   1. BENEFIT:  Allow direct access between Anacostia and southern Maryland to job sites in southern Arlington and the City of Alexandria.

Additionally, this strategy will explore the benefits of making improvements to several of the system’s core stations:

1. Pedestrian tunnel between Farragut North and Farragut West;
2. Pedestrian tunnel between Metro Center and Gallery Place;
3. Increase amount of vertical capacity at Union Station;
4. Increase transfer capacity at the three core transfer stations:  Metro Center, Gallery Place and L’Enfant Plaza

In the fall, we continued to provide the TAG with model results of several strategies designed to support the goals of increasing core capacity, providing adequate access and enhancing surface transit.  The model results of these strategies highlight the myriad methods that can be employed to meet the goals of the RTSP and their varied impacts, ranging from moderate to significant.

The planning process for the RTSP has been an iterative one which allows for the exchange of information and feedback from the TAG members.  The fourth meeting of the TAG included a review of the model results of the Base Case or Max CLRP and these strategies: New North-South Yellow Line on 10^th Street, SW/NW; and a New North-South Yellow Line on 2^nd Street, SE/NE.  The results of these model runs showed the impact of each of these strategies on the passengers per rail car during the peak hour and the impact of rail inter-lining at key rail transfer points like L’Enfant Plaza, Rosslyn and Metro Center.   These strategies address the need to increase core rail system capacity, one of the goals of the RTSP.
