Nostalgia & History > Unknown Photographer - WP 2002Date: 12/14/18 23:38 Unknown Photographer - WP 2002 Author: refarkas Date: 12/15/18 00:04 Re: Unknown Photographer - WP 2002 Author: krm152 Very nice roster photo. WP was late in adopting seal beam headlights.
Thanks for sharing this photo. ALLEN Date: 12/15/18 01:01 Re: Unknown Photographer - WP 2002 Author: boejoe Did this style headlamp come from steam locomotives?

Posted from Android Date: 12/15/18 08:45 Re: Unknown Photographer - WP 2002 Author: YukonYeti The “excess amount light bulbs” might be an old wife’s tale. A more logical explanation is the “golden Glow” headlights gave a wider field of light, important in the confines of the Feather River Canyon. Perhaps the same reason the DRG&W and WP later ordered Gyralights.

Date: 12/15/18 12:38 Re: Unknown Photographer - WP 2002 Author: TomG Yukon you are quite right. Virgil Staffs book goes into great detail about headlights and lenses and bulbs and the effects in the canyon. FTs actually had a prism lens applied in Oroville and taken off in Portola to give more light in the canyon. From Portola east the crews didnt like the dispersed light as why they were removed. WP tested sealed beam lights and found in the begining, Sealed beam lights tended to burn the bulb in the center reducing the avalible light. It was decided that the golden glow provided better light and current technology on seald beams was not superior. That was taken form WP mechanical department records. Now as for the change after 68 to seald beam, either the bulbs were better or bean counters finally prevailed since that was the beginning of the Christy/Flanery/Perlman era.
