"Abandoned" makes it sounds like there are tracks in place for the length of the line, just no trains running on it.

But that's not the case - in the 4km the line used to run on there are 11 remaining artifacts, the largest being a station building (old North Carlton station), the smallest being a single 4 metre track section in Edinburgh gardens, or the one remaining concrete pylon base. They are the vestigial traces that need to be mapped. As for the rest, it's a mostly a park now with a bike track along it (the bits that aren't are houses) ... and that's what it should be mapped as.

I believe abandoned railway lines should be mapped.

If it is necessary to have a current physical feature to justify mapping, then the railway formation (cut and fill earth works) generally remain, particularly if the railway reserve has been retained as a rail trail, road or linear park.

Right. So if I delete the mapped rail line that doesn't exist, then remap the individual pieces of track, the remaining point and weighbridge, three overhead pylon mounts, one remaining station and one cutting that remains as historical artifacts, then everyone is cool?

If it exists on the ground now, it will get mapped. Otherwise, it won't.

    Actually, the slope is slippery. People have made it about old

    been completely developed over and no trace remains.

    Mapping the traces of an old rail line isn't historical mapping.
    If there are currently traces there then it's mapping the present.

        Admin boundaries are a slightly different thing - they may be

        The problem with the historical thing is that to my mind, it
        is a slippery slope. There's a park near me that is currently,
        well, a park. But I know that it was previously a quarry, and
        then a rubbish tip/landfill, cos there is a sign saying so.
        But I certainly wouldn't tag the parks as a quarry or
        landfill, because it isn't. It's a park....


    IMHO this slope is not slippery. Every time the "do we map
    historical stuff" debate comes up, it's always about train lines.
    That is, we're still at the top of this supposedly slippery slope,
    waiting to slide down. Somehow, train lines are different. They
    just are.

    To reiterate what I said before in different words: we're not
    mapping "the 1890 route of a long forgotten train line". We're
    mapping the vestigial traces of a former line. And I'm absolutely
    not proposing to record any information about when lines opened or
    closed, or were re-routed or whatever.
