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.

here’s the easiest way for me to explain this i can think of.
new RC plastic track
old metal rail track minus the metal
to put metal on the new RC track in order to make 9v trains work you need to
shave the top and sides of the rail so that the metal rail will fit over the
plastic.
will sanding just the top work?
in a word no.
how do you shave the rail so the metal fits?
honestly i’m still working that out. most likely heat or a custom made tool
using xacto blades will do the trick.
do you have to make the holes in the rails
no, the holes in which the mounting tabs are in 9v track are not apsolutly
nessasary IF you use the right glue.
what type of glue?
epoxy or CA
will metal tape and or paint work?
yes, for a while. the rubing action of the motors and wheels rubs it off or
though within minutes or hours.
why will it rub off?
lego picks up power from the inside edge of the rail unlike all other model
trains. this is actuly a feature of lego trains as it automaticly cleans the
rails as the train goes by.
i hope this helps clear up the confusion.
