The latter sounds like 7416 was doing 7416 things and likely failed at Haymarket on its previous trip, with the 4 hour window enough for Jesmond to get it going again. In its time at Ashington I don't think I had a single trip on it when it was working 'properly'. 

Wouldn't be surprised if the 306 Pulsars were also replacing 7416, most of the problems it had when I was on it got worse when idle, or starting back up after cutting out while idling (or not starting back up at all).
