So... do you really need something with a non-trivial profile -- a “channel”,
as you say, or does the top of the rail just need to be shaved down? I’m
thinking that a woodworker’s drum sander (the stationary kind used for
thickness sanding planks) and a simple jig to hold the track would make short
work of re-profiling the top.

It’s a question better answered by a modder like Ondrew, but I think you are
correct-- “channel” probably wasn’t the best description. Shaving down would
work AFAIK. That is to match track height.
Now the 9 volt train motor actually picks up power from the track along the
inside of the rail. The wheels are cleverly spring-loaded to maintain contact
with the inside of the rails, even in curves.

Does the web of the R/C track have the through-slots that the metal clips
fold into?
|
Not AFAIK
| |
Does the rail head width also have “metal allowance” that needs to
be shaved down? -- Maybe that is what you mean by “channel”?
|
Not sure about that. My initial thought is that a slightly thicker rail would
actually improve conductivity.
