28m at Rupert
32m at Renfrew, Kaslo and Slocan where the cut starts.
Then grades are downhill through the cut to the false creek flats at 6m.
Conclusion: raising the railway on a viaduct at the top of a hill makes the grades worse in both directions. Lowering the railway in a trench would be better for grades. Perhaps we might see a combination of raising the rail bed and underpasses at Renfrew and Rupert.
