I was simply attempting to provide some context to support the assertions of the OP’s user. Nothing has actually changed on the 410, which continues to do a double runs to Towpath Way and Christie Drive, as detailed on https://tfl.gov.uk/bus/route/410/, and there are not any Beckford Road bus stops being served.
The bottom line is that no arrivals data is currently available for the Towpath Way or Christie Drive stops, which are still being served. However arrivals data is available for the Beckford Road stops, despite the stop data stating they are not serving any routes, and more to the point not actually existing outside of the API.
Oh and ‘Davidson Road’ stop is in Davidson Road, about a third of the way from the south end. It was once called ‘Davidson Road Shops’ and eventually the name was changed to reflect that the shops had long gone. The stops are actually closer to Stretton Road than the ‘Stretton Road’ stops are. The name is a bit unfortunate but I can’t offer a better suggestion.
