I'm also having trouble figuring out what Lansdowne Station egress looks like when Phase 1 is completed. They shut down and demolished the old (2014!) stairs from each platform to Beacon Street in December 2018. I can't tell whether the westernmost side of each platform will have secondary egress up to Beacon Street, or if passengers alighting at Lansdowne will have to use the station's central stair/elevator towers to access the new deck and thence Beacon. Some of the plans make me think the outbound platform has secondary egress but not the inbound platform, and some of the plans make me think that neither platform will have stairs anywhere near where they used to be on the Beacon side. Can anyone figure out the answer?
