There may be other indicators of older lines:
Also, it is common in my part of the world for older roads, bridleways,
railways, some farm tracks and even some footpaths to have tree-lined
hedges. They're obvious from aerial imagery, although it may not always
be apparent what type of way they enclose. Mapping the paths of
former railways indicates what those ways were (although it's possible
that some sections may have been repurposed as roads, cycleways or
I didn't add this former railway, but I've tweaked it.
In the area shown, from Cardigan to Cilgerran it is part of National Cycle
Route 82. Part of that is also the access road from Cilgerran to the Welsh
Wildlife Centre. These are well documented as following the route of the
former railway. I've only mapped the hedges lining the route at
the Cardigan end, but they're apparent elsewhere along the route.
Erm, what about cases where a road or footpath or cycleway has been

Sounds reasonable to me.

What, in principle, are the differences between historic maps, a website
that a route has been constructed over an old railway line and a sign at
the start of
the route saying that it follows the path of an old railway line?

Do we? I'm not sure that I would map a razed railway line where no trace
of it remains. I'm not sure if I would map a short section of line that
built over and no trace remains if there were clear traces of the rest of
I wouldn't remove it if somebody else had mapped it.

mappers not participating in discussion" and "person has fringe opinion

We don't have humming. The best we can do is note that several people
have expressed differing opinions and that the matter is contentious. We
can also note that certain edge cases have been highlighted. I'm with
on this one: at this point in the conversation it is unhelpful for the wiki
be changed to state that these things should be removed whenever they
