And as a regular user of the 84 (for obvious reasons), YJ07VRK is ok but it has been known to be getting crowded on certain journeys - plus something with a bit more capacity maybe handy once the Bridge Closure on Durham Road starts in May depending on whether or not Stagecoach stick with the diversion the drivers have been informed of (which could mean further up Durham Road could be seeing 3 58s together)
