They are.  I guess this is one of the reasons why your waterway hasn't been
mapped.

If you are using potlatch, then the options menu allows you to select a
background layer.  Don't count on landsat being acccurate enough for your
purposes either.

Also true - but this doesn't necessarily stop them being useful.

So what is the problem you are having, if not with the location or the tag?
If you know where it is, and you know how to tag it, then you are surely
99% of the way there?

Welcome to OSM.  You can use the imagery available, you can walk the line
with a GPS, you can find and interpolate from surrounding features, points,
or a combination of the above.  You can find an out of copyright map from
when the railway was built, which may be able to use to map the route once
you have one or two points.

What is the town you are mapping?
