So the fact it only 'served Coach Road towards Washington' will be down to the circular-style nature of the service, I think..?
More like lack of Demand from Passengers, A Bus could easily go around Coach Road in Both Directions, but there is no need to do that with the Estate being Circular, as there would be no benefit from it.
As I have said in the Past, Coach Road has around 12 Bus Stops situated on the Perimeter of the Estate, each within 2 Minutes Walk of Every Home with Services 4/56 and M2 Providing 14 Buses Per Hour to the Estate, Other than the OAP's I can't see the point in the 37 Serving the Estate, why do you think GNE scrapped the W3 and Replaced it with the M2 a few years ago.
