First are the main operator in the city, mainly with a mix of Volvo B7RLE and B7/9TL deckers.... They also operate the Park & Ride operation with branded silver vehicles. Transdev York operate a lot of tendered work on behalf of the university etc (main one being Unibus 44), obviously they have the commercial Coastliner operation run from Malton depot too.

Arriva operate the routes out towards the South East, mainly towards Selby, with the flagship Max 415 running every 15 minutes. They also operate 3 Solos on City of York tendered work. East Yorkshire operate a variety of routes to Hull, Beverley and Market Weighton etc using both single and double decks.

Other less frequent services are operated out to the North and East by Reliance and Stephensons, mainly hourly operations, with other tendered operations by Utopia towards South Milford and Sherburn etc. NX call in a few times a day on 425, 534 etc and Megabus operate a Plus service into York twice a day I think it is.

I've probably forgotten a few, and there is obviously other operators on school services and Racecourse shuttles on race days etc
