GENERAL DESCRIPTION
The Wheel arrangement is 'B-B' (i. e. the locomotive has two bogies, each of which has two individually-driven axles).
The locomotive may be operated singly, or may be coupled, to form a two-unit or a three-unit locomotive, with other locomotives which carry the 'blue star' coupling symbol.
Some locos were modified to work 'push pull' with '4TC' sets, these were rakes of four coaches that were to all intents and purposes Southern Electric Multiple Units with driving cabs but with out traction motors. They were either coupled to full 'EMUs' or to the modified class 33s. Locos like ours were called 'KAs' and in the 70s re numbered 33 0xx, the modified ones were known as 'KBs' and renumbered 33 1xx. Also a handfull were built to a narrower loading gauge to work the Hastings line, these were known as KCs and later renumbered 33 2xx.
