I live nearby and thought to visit Walpole Station around 8AM. Keolis had workers everywhere, mainly to watch the signaling and gates along the wye it seemed. Train 743 to Foxborough came through Walpole perhaps a couple of minutes late. It took the wye at the usual crawl. The signals on both the walkway to Rt. 27 and across the station driveway performed well with all the workers looking on. The station parking lots were already full. The platform had people waiting for the next inbound from Norfolk, so all looked well.
I will say that if this project goes well, Walpole Station will be crying out for a redesign. Having trains cut right across the far end of the existing platform is not terribly desirable. The station really cries out now for a high level platform further inbound to facilitate Foxboro Line trains stopping in Walpole. How that ties into the existing platform I don't know. It would also be great to separate pedestrians from the inbound end of the wye, but short of a mega expensive under or over pass for pedestrians, I don't see how that will happen, but given that about 500 apartments are about to rent out in downtown Walpole, we will be seeing major changes to this station somehow. Clearly the MBTA is waiting on passenger number results before they commit $$$ to a major Walpole station redesign.
Train 743 seemed to accelerate well down the line to Foxboro once it cleared us and as I type this in my nearby home, I hear regular train and horn activity, so there is quite a bit of train traffic, but then too, the double tracking project to Norfolk is also underway and Franklin trains lay down on the horn there too in order to clear the nearby workers.
In short, it looks good.
