Western Railroad Discussion > question about headlightsDate: 10/26/24 07:20 question about headlights Author: dragoon I've seen quite a few pics of locos in the steam days where the running loco's headlight is off in a daylight shot.
was there mandate that a headlight is always on instituted? and BTW, some lines had extra warning lights (Mars, Gyralite, etc). Was that a regulation or was it up to the individual RR?

In 1950 T&P required all leading and switch engines to have a lighted head light on all the time.

Date: 10/26/24 08:39 Re: question about headlights Author: 57A26 Rules before the 1940s generally only required the headlight to be displayed at night. The change coincides with the proliferation of diesel electrics in road service.
Saying the 1940s is a generalization. There isn't an exact date when the railroads changed.

Date: 10/26/24 12:43 Re: question about headlights Author: railstiesballast Some of the "Mars" or other moving headlights seen on a few late era steam engines may have been activted if the train brakes went into emergency.
This was done to warn another train that could be approaching the stopped train on the opposite direction in double track territory to reduce to restricted speed, prepared to stop short of any derailed cars that might be fouling the second track. This is the function of the Southern Pacific's red light on top of the other headlights (on diesels).

My memory of that operating rule was, an opposing train was not allowed to pass any locomotive/train displaying that red warning light. After the cause of an emergency brake application, which activated the red warning light, was determined and that no equipment was fowling the adjacent track, the Engineer would then re-set the brake valve, and subsequently reset/extinguish the red warning light. > This is the function of the Southern Pacific's red > light on top of the other headlights (on > diesels).

RRS added a daytime-headlight rule to their rulebooks around 1950. Date: 10/27/24 16:55 Re: question about headlights Author: SR2 ICC instituted rule in August, 1951.
