Here in AUSTRALIA we call that a 'Thoughty'.
A blunder in surveying led to the suggestion that a half-mile tunnel be blasted through the hillside. An idea that would have cost the CPR millions of extra Dollars.

That plan was quickly discarded and an alternative route was found around the mountain.
This incidentally, shortened the rail line by a mile and avoided two long hills, and most importantly, It got rid of that ridiculous idea of a Tunnel.
What on Earth were these early Pioneers thinking about ?????
