No evidence when I rode the UP North 2 weeks ago.
However, they still need to prepare construction drawings for the revised plan. That can take 18 months or more, and Metra only canceled the former plan last August. I imagine that, with the increased neighborhood impact of the new plan, Metra has to work through all the city politics as well.
In other commuter-rail construction news, they've started work on the 130th/Torrence project. The included pedestrian bridge (in red) is awesome.
I'm guessing it's intended to provide pedestrian/bike access from Hegewisch to the Ford plant gates and possibly the Red Line when they build it out to 130th.
