Another one bites the light

[NW Mailing List]

I think you are using the incorrect term, "daylighting" infers  
removal of the earth and fill, as well as the top of either the  
brick, or conctete to convert the tunnel to a cut. This was done to  
the former Shawsville tunnel back about 1990-91. The changes here at  
Cooper are essentially cutting out the roof a total of 9 inches by my  
reading.

Generally, there is not much to document (at least photographically)  
on this type of operation, as very little that one can see outside  
the tunnel is changed.

According to the article, five of the 28 tunnels involved lowering  
the track level, the rest were like Cooper, by raising the roof.
