Unfortunately, the incident this morning on the A19 caused major traffic delays throughout the morning, and these delays were ongoing through the day. The A19 didn't fully re-open until 09:30am - and I'd imagine all of the Tyne Tees Xpress buses are out in force by this point.

Further delays caused due to ongoing work on the A183/A19 junction:

There's only so many tachograph-fitted vehicles at Riverside, and there isn't a huge number of spare drivers on the Tyne Tees Xpress rota to be able to cover delayed runs. 6084 started off the day on the Toon Link, but ended up covering on the Tyne Tees Xpress, and there was a report of a Highwayman on there as well.

I wasnt aware of the incidents at the time and there was nothing on GNEs Facebook either when I was waiting for the 0813 at Heworth, as for coming back the issue which caused tailback were between the Houghton le Spring Slip Road and the one for Penshaw/Pennywell, there was a Police Car at the side of the Road and one those that would be used to cut off the Lanes with Illuminated Signs on the side, so there must of been another collision this evening heading towards Newcastle etc, I got a few shots of 6084 in Middlesbrough.

It could of been depending on how late it was, as noted above the one I got was 80 Minutes late coming into Heworth.
