Norwester;

Welcome to ECN.

First off, I have compiled a "Work In Progress" Glossary of terms we commonly use here in the Forum.
It can be found in the Technical Reference Section under the Topic / Name:

ECN Glossary

Click the "Colored Text" above (ECN Glossary) to go directly to that page.

Next thing, I see you were an Electrician with a Railroad, within the Signals Department and Communications.
There's quite a few Members here - including Myself, who will enjoy discussing Railroad things with you.
I have a few questions of my own - such as what types of Signals did you deal with (Block / ABS, Crossings, Detectors, etc.), did these Signals use AFO detection, Control equipment - Relay Logic or ?, and a few things about Communications (Radio, Hard-Wired, Cab Signal + Trackside Detectors, etc.).

Hope this doesn't scare you away [Linked Image] ... joking.

Have some Railroad Pictures + a few documents regarding some C1 North American RRs, posted in the Technical Reference Section also.
