• Caption: The first two #5 East Boston Tunnel cars arrived for acceptance testing in February 2007. They were shipped to the Orange Line's Wellington Shops, because there is a long third track there that cna be used for testing the cars during the day without disrupting regular traffic (the track was originally intended to be an express track, but that never materialized). The cars would run back and forth between Wellington and just north of Sullivan Square. I found them idling at Wellington on February 26, 2007. This is 0704.
