The Norton-end of the 37/38 doesn't justify an increased frequency however - the busiest section of the 36/37/38 is Park End to Norton, with the extremely busiest section being Norton to Middlesbrough. Going non-stop between Middlesbrough and Thornaby would then leave Middlesbrough without any true link to Teesside Park (the 36/37/38 are the only link they have - even if it's a 10 minutes walk to the Park) as well as abandoning the Wilderness Road. Reliability of the services is down to external factors (36 has the level crossing in Billingham, then add any roadworks on top of that).
