As a cost-saving measure, Sound Transit will begin running one-car trains on evenings and weekends when no event makes high ridership likely. The one-car runs will begin as early as 7:30pm on weekdays and in some cases all day on weekends.
Spokesman Geoff Patrick explained:
It is a cost-reduction measure in response to the recession’s significant impacts on agency revenues. Demand during those late-evening hours can be met with one-car trains, and the agency will save about $460,000 annually. We will operate two-car trains when there are sports events or other happenings that will increase rider demand.
The change does introduce some operational complexity in that in-service trains must be split in the O&M Facility or the Pine Street Stub Tunnel, but there is a net savings in doing things this way.
