Tacoma Rail is scheduled to update the City Council on potential new services it could provide to main line railroads during the April 18 study session. The aim of new services would be to improve rail efficiency in Tacoma and the Puget Sound region, to support the continued growth of the Port of Tacoma and to enhance economic development. The Council will not take public comment during the study session. CityPost (Channel 85 on Click!, Channel 77 on Comcast) will air the audio portion of the session live. Replays of the study session audio may be heard Wednesday nights at 7 p.m. on CityPost (Channel 85 on Click!, Channel 77 on Comcast). On-demand audio archives are available on the Web within 24 hours of the meeting at http://www.tvtacoma.com .
