If we're going down this route, imo the better thing would be to scrap the utterly ridiculous W2 that has no purpose and use that daytime resource to run an evening service on the full route of the 51 and 54.
Backworth and the North of Whitley Bay have absolutely no service beyond 8pm which is pathetic by how urban the areas are.
At the same time I'd change the 57A to run from East Hartford to Whitley Bay on a Sunday / Evenings. The Whitley Bay to North Shields extension is just pointless - other areas that have absolutely no bus service currently.
