Re: Remember Superelevated Track?

Now, if a curve doesn't have ANY superelevation, doesn't that mean the outer rail is worn out long before the inner rail?

I was taught that the amount of superelevation is chosen based on the particular mix of fast and slow trains that is expected? Slower trains will wear more on the inner rail, faster trains more on the outer; and the aim is to have both rails be equally worn so as to not replace them earlier than necessary.

When a large category of trains is removed from a line, this would change the mix of fast/slow trains, so it makes sense to adjust the superelevation.
