This is mearly out of curiosity. While traveling on board most of the trains here I notice that the interior lighting on all vehicles are the same, bright white (to a pale brown depending on cleanliness and condition of the light and cover), harsh and uninviting. Is it for safety and standardization? in the day time its understandable but at night the florescent light is pretty harsh. Is it possible for a TOC to put in place an automatic dimmer so that once a train departs a station after 2 minutes the lights dim to about 50% brightness? perhaps implement colored lighted walkways and underglow like on busses and airlines. Basically make the train more inviting especially at night.
