No .. just two things at once. Sorry .. should have been

Where the railway has completely gone, do you still want

Railway=dismantled to be used.

And your answer is yes (I think).

There is also proposed, planned... and under construction.

Proposed and planned I cannot verify .. many things get 'proposed' or 'planned' by politicians .. and there is no sight of them for many decades if at all.

Under construction I should be able to verify.

Good question. Pose it on OpenHistoricalMap ? Maybe they have a solution.

Discussion. Well as far as I'm concerned.

No I, for one, don't want you to go away. Quite the contrary!

I do take your point...
You want old things that may no longer be present in any shape or form 
to be represented ?

within OSM?

I sympathise. But is OSM the place for these? (I'd call them 'ghosts', 
visions of things past.)

However ...
Why stop with railways? Roads and buildings have history too.
Some OSM people mantra on about verification. How are these things to be 

Umm the old 'Tank Stream' in Sydney ... that was a fresh water source 
for the establishment of Sydney.
Most, if not all, of it is underground. Should that be mapped as
and then other tags to reflect what it is now ..
? Probably. But I would have problems with verifying its' location. Humm..

So I'd not let 'us' (as in OSM) off with some exception just for 
railways, other things should have the same consideration.

You have raised a good issue. An it is a policy issue .. and OSM is not 
good with policy. Hence this lengthy thread heading off in may directions.
