While on the topic - if you were renewing railway track in a mine,
expedience the only concern - what would you use?
The low rolling resistance and being able to simply push wagons to a
tonne weight along levels you cannot stick your elbow out in is
fundamentally advantageous.
Saw on a US website that still sell rails for mine railways.
For infrequent hobby use you would use?
Access into mine limited - no adit (horizontal) access nor sloping
decline - is shaft only.
Wondered whether you could lower flat bar (rectangular section) down the
shaft in long lengths and weld to steel "ties" to make a functioning
railway (not going to need expansion joints down there - not many frosts
and not much "solar gain" on heatwave days!).
Saw on a video a coal mine in Pakistan where they use angle-iron for
rails - shows rope-worked decline the wagons come to surface along.
Which I take it is cost-justified?
There are points / switches - cannot have double-flanged wheels to
self-stabilise track, for what it's worth...  And yes the tracks do
snake around with curves in following the lodes.
