The Class 37 was originally referred to as an ‘English Electric Type 3’, a Class 40 as a ‘English Electric Type 4’.
This seems to work fine if you have ‘types’ from various manufacturers. But wasn’t it rather confusing when you had what are now different classes from the same manufacturer?
I was prompted to ask by reference to the ‘Sulzer Type 2s’ or BRCW Type 2s, which included what are now Classes 24, 25, 26 and 27.
In the preTOPS era, was this level of distinction not as important?
Given the differences, though, in power of the various Sulzer Type 2s, how would planners specify which was needed? Reference to ‘D number’ range?
The Peak Classes 44, 45 and 46 would have had a similar issue, I’d have imagined, all bring ‘Derby Type 4s’.
