I’d be interested to learn more about the history and development of the ‘AC Electrics’.
As I understand it, there was one prototype, a Class 80, which developed into Classes 81-85. These then led to the 86, then the 87.
What were the principle design differences between them, performance and reliability?
‘Cosmetically’, the 81-85 look very similar: the 86 has a less slanting front, and the 87 was the first to be designed without an integral headcode (also distinguished by two instead of three windows).
I look forward to some knowledgeable comments from those who familiar with them.
