It was decided by BR and EE to carry out a programme to refurbish the class and modify the engines with new parts designed by the engine manufacturer.
The locos also had modifications to their nose ends, losing the gangway doors and headcode discs in favour of a central roller blind headcode box.
The livery also changed to two tone green with grey roof similar to that of the British Rail Class 55s so they looked every bit a 'Baby Deltic'.
The locomotives gradually returned to traffic and became very reliable in traffic except for continuing coolant system problems.
The allocation of all ten locomotives in October 1967 was Finsbury Park.
