ATW are still running a 158 diagram on the South Wales services. Here it is, it is Monday to Friday I am not sure about weekends. So for anyone who wants what might be a last ride on a 158 (with the exception of replacement broken down 175s
) then here is the diagram:
05:00 Camarthen to Manchester
10:34 Manchester to Milford Haven
This is based on my sighting this week so it might change.
