For a time ago I saw a picture of a BR standard class 9F equipped with a big electrical headlamp. This in consideration of banking duties. Steam locomotives in many countries used to have such permanent fitted headlights, but were this sort of lamps ever considered to be introduced in the UK? (for example by the new BR standard class?) (I`m not thinking of these white ,small ,portable lamps) mounted on brackets. For power supply to these lamps it was often mounted a steam turbo generator, which also gave power to other electrical equipment. I don`t know if this have been used in britain? Some locos had also lights mounted upon the running plates above the motion and made maintenance easier when it was dark. The BR standards with their high mounted running plates never get such?
