[RITSlist] ROCK ISLAND DIESELS WITH "TUNNEL???" LIGHTS

[Philip Weibler]

Hello, Jeff and List - C.J. "Bud" Frey was the electrical engineer at Silvis Shops in the 1950s-'60s.  He designed the circuit for the 'bug eye' or 'frog eye' lights. The lights would flash alternately side to side when the locomotive was moving.  It was hoped that this would make trains on the plains more visible to motorists.  The first applications were to U25Bs in the early '60s.  PAW

  These are a predecessor to today's ditch lights.
  I believe they started out in Minnesota during the early 70's to improve visibility at grade crossings - for the drivers, not the engineers.
  A number of U25/28Bs and GP35s had these. One early passenger diesel had them too. #626?
  Once the experimented ended, maintenance on them ceased. They were left in place, but very few, if any, still had lenses by shutdown.

  The Maine Central purchases (U25B) and Union Pacific returns (U28B) carried the housings until their death (scrapping).

  This is just a quick summary, I'll turn it over to the folks who know stuff now...

  You are talking about the lights on the corners of the nose(short hood) of cab right. These are classification lights. To classify the train it's powering.
  Can any one answer this better.

  I'm trying to find out why some of the Rock's units had lights on the  
  front corner tops of the cabs.  I have a picture of GE U-Boat #208  
  taken at Topeka, KS and the unit has a set of lights on the top front  
  corners of the cab (like ditch lights, but on the cab).
