A view from the station, just look how busy the stabling point outside the old shed (then used for wagon repairs)was back in the late 1970s.
In the early 1980s as I recall there were 6 pairs of Cantons 37s allocated outbased at Barry to work MGR trains to Aberthaw.
The coal came from various South Wales locations, collieries and loading points.
From the Cardiff Valleys I can remember Penallta, Lady Windsor, the Ocean Complex (and Cwm Bargoed I think).
From further afield Blaenant and Steel Supply at Jersey Marine.
The wagons were formed in 28 wagon sets and the 37s worked them to Aberthaw Reception siding,
from there a couple of Cantons Slow Speed Fitted (SSF) class 47s were employed to work the sets around the power station loop
