The designation for standard locomotives fitted with ETH and therefore used for passenger, mail and parcels use.
133 locomotives had been fitted by the time renumbering occurred, and shortly afterwards the sub-class had settled down to 154 locomotives, numbered 47401–47547 and 47549–47555.
Later, further Class 47/0s were converted to Class 47/4s and renumbered into the series from 47556 onwards, which eventually reached 47665.
