Note(s)
1	Many locomotives had their steam heat equipment removed prior to reclassifcation in 1973. By the time of reclassification to Class 37/0, the steam heat system was obsolete and where still fitted had been isolated.

Note(s)
1	Locomotives that derived from those that were built with centre indicator panels were fitted with roof mounted warning horns and were therefore higher.
2	Some locomotives had their steam generators removed/isolated and the boiler water tanks then converted to carry fuel instead, extending their range of operations.
3	To avoid situations when working in multiple with refurbished Class 37's, all unrefurbished examples were 'capped' at 80 mph after 1985.
