158838, in Transport for Wales white livery, arrives at Wolverhampton forming 1J11 1008 Birmingham International to Aberystwyth and Pwllheli service on Tuesday 06-06-2023. I assume that another unit was added somewhere on route otherwise it would have been difficult to provide service to both destinations from a 2 coach 158 unit.
