[PRCo] Re: 42/38 on Smithfield Yellow-Green Light

[Bob Rathke]

Don't the traffic lights in Pittsburgh still have the overlapping green/yellow indication? 



I recall that in the 1960's Pittsburgh was one of the few (maybe the only) city in the U.S. with overlapping traffic signals.  Also in that era, Canton, Ohio had simple red & green traffic signals - no yellow.

Hi Folks, 
Take a look at this of the 42/38 on Smithfield: Â  http://www.railpictures.net/viewphoto.php?id=275722&nseq=45 

Remember when the traffic lights used to give us "green" THEN Â  "green and yellow together," then "yellow," and finally "red?" Â  Â The photo illustrates the former green/yellow signal.
