I've been seeing 85's on routes out of Kendall over the last few weeks, and sometimes at Harvard too (96 often gets em, although last night I saw a Midwest rehab on teh 96 at Davis Sq.). I've seen some 85's, 86's, and 87's at Kendall this week -- I think they were all on the Lechmere shuttle, but its not like you could tell by the destination signs.
Update: As of Thursday afternoon, there were a bunch of old RTS's on the Lechmere shuttle -- 84, 85, 87's and even 8017. Still some 0xxx RTS's, but few with the "Green Line" stickers. The Neoplans seemed to only make the one appearance.
