Amtrak 474, CT Rail 4462, and CT Rail 4461 at Wallingford Station

I've been on the lookout for one of the Amtrak 50th anniversary engines that have been passing through. By chance I stopped to see the wallingford station and the first thing I see as I entered the platform was engine 46 heading northbound. I stuck around to catch CT Rail 4461 and 4462 again as well and then I got a view from the overhead bridge. I was hoping to also see Amtrak 475 which I believe is also often using a 50th anniversary engine, but it was over an hour late.
