There were other operators on the Doncaster and Goole route, or parts of it.  For example, Moorends and Thorne also had a bus service to Doncaster which ran via the villages of Hatfield, Dunsville and Edenthorpe.  Severn's  Cressy, Parish's Felix, Smith's Renown and Harold Wilson's Premier operated this route jointly.  Several others, including William Lowe's Mabel (of Stainforth) and Jimmy Firth's Irene, Barley's Corona and Hopley and Richardson's Majestic also ran between Thorne and Moorends, Thorne and Stainforth or Thorne and Goole.  The proliferation of these bus operators was associated with the establishment of Hatfield Main colliery (at Stainforth) and Thorne colliery (at Moorends) and the consequent expansion in the population of Thorne and Stainforth.  Robert Store, the owner of a bicycle and hardware shop and petrol filling-station in Stainforth also held licences to operate on the Doncaster and Dunscroft and Doncaster and Goole routes with his Reliance buses.

    In 1933, the Mabel bus business was purchased by Mr Wilson, giving him additional journeys between Stainforth and Moorends and some which extended to Dunscroft (Kidson's Stores).  Albert Braim ceased operations on the Armthorpe route in 1940, and the business was shared between the three other existing operators.

    Things were not always as they seemed in the Blue Line fleet.  WG 4059, pictured here in  June 1948 at Doncaster, is sporting a Guy radiator but is in fact a Gilford.  Just visible behind is the first double-decker to join the Reliance fleet, AML 996 (see also below).  Once No 78 in the Leeds City Transport fleet, this futuristic machine of the AEC 'Q' type had full-fronted 60-seat MCW bodywork with centre entrance and side-mounted engine.  It is pictured below in April 1949, shortly before  being withdrawn and scrapped.  Both pictures are by Roger Holmes.
