Actually, as we saw when part of the wall began to collapse about 18 months ago, and was replaced, the Roseville cut is in bad shape. Both retaining walls are in need of total replacement.
I have been told that the Roseville cut was the first grade seperation project undertaken by the DL&W, and as such, they were learning as they went. Later projects used much better concrete.
Also, if you are interested, look on the north side of the Roseville cut, just under the 280 overpass. You will see a small recess, with a new section of retaining wall, about 3 feet back from the existing wall. This is the section that had to be replaced as it had begun to colapse and was in danger of total failure. You could not tell from inside a coach, but on the head end it was quite obvious that the wall was leaning in towards the track area significantly. In fact, while in the rest of the cut there is enough room to stand between a train and the wall (still a bad idea), that section was so close it would hit the mirror on the side of the locomotive if it was not tucked in.
The rest of the cut is not in danger of immediate failure, however, more and more problems will continue to plague this area if the walls are not replaced.
