[quote]QUOTE: Originally posted by arbfbe Futuremodal, As is was explained to me by long term employees in the operating department, the east portal of the tunnel would be just out of the horseshoe curve at Bryson and the west portal would be between the tunnels at Adair. Supposedly it would be a gradeless tunnel but you would have to check elevations between the two points to confirm that. The length of the new tunnel was reputed to be equal to the total length for all the tunnels and bridges it would replace. Additionally, about 70% of all rotary trips had historically been on the line that would have been abandoned. As the story goes the tunnel had been an integral part of the original construction but no one had yet built a tunnel of that length and the MILW Board of Directors was hesitant to go into such a project only to find unstable soils and formations inside that would immensely increase the total cost of construction. The tunnel would have additionally eliminated helper service for most trains. Oh but for today's drilling technology and the ability to drill core samples for the entire length of the proposed tunnel. The tunnel part of the story has been confirmed but some of the details I have mentioned may be part folklore handed down amongst employees over 60 or more years by the time I heard them. There must be surveys of the proposed bore that someone may access. [/quote] Michael Sol describes the elimination of Tunnel's 19-34 with this project, which clearly shows a substantial grade realignment as well as the new tunnel. It may be that this was a long term project borne of the original plans, and then the grade realignment was added to later plans.
