Sub class variations:

Original locomotives built with steam train heating, many later converted to electric heating, all remaining locos devoid of train heating equipment. (Some now 47/2)

Modified 47/0 or 47/3 locomotives fitted with green circle multiple control equipment and extended fuel tanks

Locomotives built without provision for train heating, thus freight only locomotives, (Some now 47/2)

Locomotives constructed with either dual (steam and electric) or just electric train heating. Now only electric heat examples remain

Converted as research and development loco for Class 56 locomotives

Class 47/4s fitted with high phosphorus brake blocks and increased ETS for overnight workings

Converted Class 47/4s with an early RCH (Railway Clearing House) push-pull system for use on the Edinburgh-Glasgow high speed service

Modified Class 47/4s with RCH Time Division Multiplex push-pull equipment for use with trains formed of PCV sets on Royal Mail duties

Locomotives refurbished for passenger traffic fitted with ETS, rebuilds of 474xx fleet

Converted as research and development loco for Class 58 locomotives
