Working in accounting for much of my tenure I saw many a bill for
truckloads of used rail ties, usually $1.50/each.

Those get incinerated today, they are toxic waste (much to
the annoyance of the railroads, who have to collect them
up and haul them off, instead of selling them where they
happen to be taken up).
