However if a down Clay empties train (ex Fowey) for Parkandillack Bch had got to B'gullow and the points (to Bch) failed the sensible/quickest way to clear the train and reduce delays to following trains would be to run to Truro ..because the CDA is near the stop blocks/east end of Truro yard suggests it was probably one of several such wgns.stabled on this sdg.
One further thought !
I think there was an exhibition in Truro Yard in the 80s-90s with some modern freight wagons and possibly it included a CDA ..note this wagon's blue paint is very clean !!
How many of the original 125-130 CDAs (modified MGR Coal hoppers) still survive ..anyone ?
Thanks for that Tony
