As someone who has hundreds (sometimes thousands) of images downloaded from my site and used in other people's pages without my permission on a daily basis (rogue's gallery here, comment about it here), and also with certain responsibilities here, I tend to check copyright terms quite carefully - I have to!  We've got an excellent "crew" around here so there's very rarely a problem in practise, but better safe than sorry!

[grahame]

I see we're on to page 2 now so I've sorted the extras in and come up with a complete list to date. List also includes netspeak items that I save seen in use here (slight policy change - avoids people having to look at lots of different places!) ...

ORCAT System for allotting fares between operators - what does it stand for?

It's actually ORCATS^▸ (Operational Research Computerised Allocation of Tickets to Services) - Operational Research Computerised Allocation of Tickets to Services.

You've left off Tarka^▸ (Line from Barnstaple to Exeter) Line and NDRUG^▸ (North Devon Rail Users Group), btw.

ps. There's a possible bug in the underlying SMF^▸ (Simple Machines Forum - The software we use on this site) code - if you put a smiley on that last line, the dotted underlining of the ABBR and ACRONYM tags stops appearing!

[devon_metro]

HSS^▸ (High Speed Services) - High Speed Services

[Ollie]

LTV^▸ (London [and] Thames Valley) / L&TV = London & Thames Valley Services (The Locals from Paddington, Branchlines, Reading - Gatwick, Reading - Basingstoke)

[gaf71]

PNB^▸ (Personal Needs Break) = Personal Needs Break (on a member of train crews diagram) In other words when you will next be somewhere with hot water, toilets, cooking facilities etc. Also SRB^▸ (Short Rest Break) = Short Rest Break.

[Jim]

Do they still use

MRB^▸ (Meal Relief Break) - Meal Relief Break?

 ::)Many thanks From a complete novice on the meaning of the those little letters know i think I can see the light   

[grahame]

::)Many thanks From a complete novice on the meaning of the those little letters know i think I can see the light   

My pleasure ... and thanks everyone else for your suggestions.  I'll keep adding them in, though, so don't stop giving me ideaa!

[Ptolemy]

I've long wanted to mention that the title of this topic is misleading, insofar as it doesn't actually tell us what THAT stands for! Tracks, Huts and Tunnels perhaps? 

I was waiting to add something useful before posting, however. I'm afraid the best I can do in that regard is to suggest TLA^▸ (three letter acronym) - Three Letter Acronym.

[Chris from Nailsea]

List also includes netspeak items that I save seen in use here (slight policy change - avoids people having to look at lots of different places!)

Thanks, Grahame!

IIRC^▸ (if I recall/remember/read correctly) - If I remember/recall correctly  (I had to look that one up externally, and even then, when I used it quite proudly here, it turned out I hadn't 'remembered correctly' at all!) 

[grahame]

Sorry, Ptolemy - can't find a single serious entry for THAT (good somment though!) but I am going back and adding the following:

RTM^▸ ((and RTFM) Read The Manual!) (and RTFM^▸ (Read The Flipping Manual (a more polite definition!))) Read the Manual
SB^▸ (Signal Box) Signal Box
TLA^▸ (three letter acronym) Three Letter Acronym

Some of which may have dropped out of common usage, but you'll hear oldies like me quoting them

[grahame]

This is just too addictive. Every time I see something that may be revelant, I jot a note down of it.   If in doubt, by the way, I am "including things in" - you may know them or not be interested by others may not!  But I have decide against (I think) all the three letter station codes better to link you here to learn that "Free of Charge" and "Falls of Cruachan" share the same shortening!
