Sigaling in the USA

Wi***o know about sigaling. Especially on the UP. What books or CDs are available to learn about sigaling?

I’m guessing that you want to know about “Signaling” ??
If you would search this forum,you would find a few things,
and there are “bunches” of books,etc. out there that should
tell you what you want to know !!

Spelling is not a prerequisite for this Forum,but it helps !!

BTW [#welcome] to the Forums.

In that case I think you’ll find it’s signalling that the railroads use (noun). Signaling is what you do to passing ships and aircraft with a mirror when you’re stranded on a desert island (verb).

According to my “Funk and Wagnell’s” and “Webster’s”;both are accecpted
means of spelling. Also includes Modeling & Modelling.

Great, here comes al-qaeda…

GCOR signals and their use…

Also look at NORAC operating rules…

Both a basic place to start…different railroads have their own signals, but most pretty much follow either the GCOR or NORAC…
