You have to have a 158 available. The 150 is combined with Cardiff Valley working over routes where 158s not cleared. On occasions is worked by a Pacer which is not very suitable for the return if there has been a rough crossing over the Irish Sea.
Sure, but I thought this thread was just pointing out where unsuitable stock is, even if that's the only stock availble for the service. Regardless, I'd be interested to know what happened to make a 158 unavailable, given that at some point between using 37s and the current use of 150s ATW did indeed use a 158 on the Fishguard Flyer?
If the Fishguard service in question is still diagrammed for a 150 or Pacer when the 67s finally arrive to release the 175 from WAG 2 (which I would hope could then release a 158 for the Fishguard) I'll be rather disapointed.
