The worst area is between Smith Basin and the south end of Whitehall siding. A few years ago there was still bad jointed rail between about MP44 and Smith Basin. They did a nice job in that area, and the track rides well.
It seems like they spend every summer surfacing the track, but every winter it gets beat up. The fact that the line runs through lots of wetlands seems to make the roadbed not hold true. The numerous curves are another source of trouble.
Excellent observations. The line along the Champlain Canal does indeed run on some very poorly drained soil and has a number of wetlands. In earlier days the railroad might have tried to drain the wetlands and add more ballast. Now, wetlands are a protected environmental resource.
Adding ballast is certainly an option. So is using longer ties. Using 10-foot long ties spreads the load a little further. Improving the drainage is more expensive, but beats adding ballast year after year after year. Maintenance of existing ditches and culverts is helpful, but to try to change the drainage requires difficult approvals from the Army Corps of Engineers and other regulatory agencies.
Fortunately, much of that expense is being borne by the Champlain Hudson Power Express. The CHPExpress project has just completed an identification of all the wetlands along the Champlain Canal south of Whitehall. They have looked specifically at the railroad right-of-way because that is where they want to bury their power cables. The transmission company is now preparing an Environmental Impact Statement and if the project goes through they will be getting all of the necessary permits.
If I were representing the Canadian Pacific Railway, I would ask the transmission company to bury their cables on the upslope side of the tracks. The cables are typically enclosed in plastic pipes and buried 5 to 8 feet deep. The plastic pipes are laid on a layer of gravel at the bottom of the trench. This would tend to intercept the groundwater moving down from the hills before it got beneath the tracks. With a few key pipes to drain the water in the gravel layer out to the canal, the drainage problem is improved at very little cost to the railroad. Instead, the cost is borne by the electric customers in New York City who need power from Quebec.
