Tomorrow, Metro riders are about to see the culmination of a project more than a year in the making that aims to improve rush hour service across the Metrorail system. Rush+, as WMATA has termed it, will add trains in overcrowded segments of the Metro system to alleviate crowding, especially on the Orange Line from Downtown D.C. to Northern Virginia through Rosslyn.

To help riders with the upcoming changes, WMATA has put together a handy-dandy website with a clickable Metro map to discuss the upcoming changes to the system. The changes include:

• Three additional Orange Line trains in each direction during rush hour, but each of the new trains will run between Vienna and Largo Town Center, not New Carrollton (as most Orange Line trains do).
• Three fewer Blue Line trains in each direction during rush hour, but the three lost trains will be rerouted onto the Yellow Line, so riders from Pentagon south won’t see any decrease in service. Also, keep in mind the three additional Orange Line trains running to Largo. In all, only one station will see a decrease in service — Arlington Cemetery.
• Three additional Yellow Line trains in each direction during rush hout, but those trains will run from Franconia-Springfield (replacing lost Blue Line service) to Greenbelt.

All in all, Orange Line stations in Northern Virginia and Green/Yellow Line stations in D.C. will see increased rush hour service. Only Arlington Cemetery station will see decreased service, and all other stations retain their normal service during rush hour (including Dupont and Rosslyn).

For Georgetown students, whose stations won’t see any new service, the biggest change to the Metro system will be with updated signage and snazzy new Metro maps (which are already installed in the trains).
