For the longest time I've been hearing the word ダイヤ and just always assumed it
meant "Diamond", but found recently it all means "train schedule". My question
is, what word/language did this word originally come from?

When used in relation to public transportation, ダイヤ means a [diagram showing
the schedule](http://www.nzetc.org/tm/scholarly/Gov01_02Rail-fig-
Gov01_02Rail021a.html), or the schedule itself. It is used not only for trains
but also for buses, planes, and so on. For example, the schedule of planes can
be called as [飛行機]{ひこうき}のダイヤ, [航空便]{こうくうびん}のダイヤ or [空]{そら}のダイヤ.
