Hello! I was summoned!
Kinda view it the same way as
@Darandio broadly. I don't see it changing hands to TPE just for the sake of one train per hour (indeed if I had my way I'd change Middlesbrough, Thornaby and Yarm to Northern stations!) and whilst it would obviously be nicer if the departing trains left from the "main" platform where the ticket office is the infrastructure isn't there to really make it practical considering the existence of a crossover from down to up from P2. I also can't see any other changes coming about either. P2 has a waiting shelter, screens and a TVM whilst the ticket office over on P1 is open on a one shift basis (0750 to 1445 with lunch from 1215 to 1245). So to open more would require Northern to probably take on at least one more member of staff if not several more. To be honest I think we should in may ways be grateful we even have a ticket office! It wasn't many years ago that it appeared on a DfT hit list of ticket offices that could be closed (and ever since I make an effort to try and buy things like season tickets or other non-online tickets from there).
I am, however, a bit more postive about Pacer replacement. As
@Darandio says it'll be 156 and 158s up here replacing 142 but I'm a bit more confident that the 142s will be gone by the end of the year. Indeed I idly wonder if we might not be the first to be rid of them as diagrammed traction!
