There are a lot of abbreviations used on the board that a novice like me do not know the meaning of. An example would be PS-2.  I see this used for both locomotives and rolling stock.  What is a PS-2 (or 3).  Another would be tvs.  What is it?  Could you set up a list of the definitions for items like these?

Hmmmm. Interesting idea. For now: PS2 when talking about an engine refers to the electronics inside, but only engines made by MTH ( Mikes Train House). It stands for Proto Sound 2. The first generation was PS. There is a huge leap in differences between Peoto Sound and PS2. MTH's latest version is PS3, that was just released in the last year. You can go to the MTH website and read more. 

 

PS2 is also a style of boxcar. There is no connection between the engine term and the boxcar term at all.

 

A TVS is a transient voltage suppressor. It is used to absorb voltage spikes to protect electronic equipment from being damaged. A common placement is across the hot and common wires where they connect to the track 

 

Dont worry too much, the more you read it will all come together.

Actually this sounds like a good idea. The question is, who wants to assemble the info, where would a "glossary" be placed so people can find it, and does the webmaster want the additional work of implementing another feature?

 

I sometimes use "acronymfinder" to figure out unfamiliar acronyms, but sometimes you have to hunt to find what's revelant to model railroading.

Topic headers could be more descriptive.  On the Recent Posts list to the right these titles are showing right now:

APPARENTLY LOST IN SPACE

Most Detail?

DARNIT!!

 

 

EXCELLENT suggestion!!!!

 

Concerning all the abbreviations, I wonder if it a result of all the younger folks that are so use to texting on their smart phones, they have literally lost the ability to spell anything anymore.

I don't think so. Acronyms and abbreviations have been popular long before the advent of texting. Years ago, I attended classes on business writing. One of the key points was on the use of acronyms and abbreviations. We were told to define any acronyms on their first use. Then they could be used by themselves later in the document.

I couldn't agree more.  No flames to anyone, but if I don't understand what the post is about, I don't bother opening it.  A specific post title helps everyone.  There has been a lot of vague title posts lately.

 

I'd really like a 'sticky' thread in the electric forum defining commonly used acronyms and abbreviations.  That would be helpful.

I would tend to agree with Hotwater. Even on this forum where we kind of pride ourselves on our language skills I've seen a large number of posts recently that are comprised of run on sentences, no capitalization, sentence fragments, incorrect spellings or incorrect words used , gig instead of jig for example, or syntax that makes me wonder if the posters first language is English or they just didn't pay attention in English class.

Don't get me wrong, I'm no Sir John Gielgud or an English major but I do find those kinds of post a little annoying to read and I can just imagine my old English teacher Sister Camelia just turning over in her grave if I lapsed into writing skills like that.

Acronym usage is fine as long as you in some way let the others know what you mean first, maybe the Moderators could sticky the acronym list for anyone who can't figure a particular one out and we can add to as the come up.

I don't know all of them either, but would be willing to start a list if you all would offer some assistance as to what some of them are.  I could post it weekly or monthly or something. It could be added to with each posting as we think of more.

 

It was difficult for me when first starting here to figure these out, still working on some. 

 

Seems like a few are already interested, so let me know. Or maybe the moderators will see this and post it as a sticky somewhere?

 

Here's a few I had to look up in order to follow along at first. There's a good chance I'm getting some of this wrong...and Yes, I agree in advance, that it's pretty bad that I had to lookup OGR.

Thanks, some good additions there. I need all the help I can get with the older stuff, don't know much about it. I've got only pretty much modern stuff, and don't know a lot about that either. Please feel free to correct anything already listed as well.

 

Can't believe I missed LHS, use that often myself, and it took me a while to figure out what that meant.

 

Just re-read the list and came up with some more also. Will try to add them in the morning without butchering Rich's nice formatting. I see the bulleted list above, will have to experiment with it. 

 

Thanks to TheBigCrabCake also, I got all yours in the 1st list, already posted.

 

If someone posts something and I miss it let me know also!  Any and all help appreciated!

 

Edit: Got the additions too!

  A list of acronyms and abbreviations would be helpful to everybody.  We all have certain abbreviations we use in our professional lives that other people may not understand.  This was driven home recently when someone used the abbreviation S.I. I had no idea other than it was a geographic location.  I think writing out an acronym on the first use is a very good idea and I will try to use this convention in all future posts.  I don't know where a list of abbreviations and acrronyms could be posted or who would do it but it needs to be done.

Can't lose what they never really learned or were even taught.  Teaching spelling was dropped as not critical in our public school system 20 years ago.

in general, i would prefer seeing the strictly internet/ non-technical terms (ie: LOL, IMHO, ROFL) also in a separate list.

 

cheers...gary

baltimoretrainworks gave me some transformer power ratings, I'll try to get the rest as I work on the list.

 

Will think about breaking it up somehow. My only concern about doing that is some may not know what category to look in. If it's all alphabetical, it would be easier to find something if you didn't know what it was to start with, but the list is getting rather long!

 

You made a post (last year) about everyone using the actual description before using the acronym, can I steal that to put at the top of the list? Might try to shorten it a bit if that's ok. Hate to steal something without asking first...

 

Thanks for the additions.

I think I have al the new additions added, will try to update the list this morning.

Here's a link to what a Z looks like.  (just a handy reference, I have no afficiation with the page)

 

Here's 2 other entries for the list:

 

NLOE : Nassau Lionel Operating Engineers.   (a club on Long Island that does special run cars each year)

RMLI: The Railroad Museum of Long Island (which also does special run club cars each year)

 

(I am not formally a member of either, but I am a satisfied participant in their club car offerings)

I'd stay alphabetical on the terms, many times someone will ask about a "ZW" they saw for sale or whatever and not add transformer to it. A newbie could look up ZW and find it alphabetically but unless he knew it was a transformer he would have to do a bit of digging.

Listing them all under transformer might get cumbersome after a while considering the number of them out there.

Thanks for the additions.

i graduated college just as some early microprocessor terms (ie: CPU, RAM, ROM, PROM, LCD, etc) were being introduced into technical articles, however, not yet in general use.  from a 'style guide' published by one of the industry magazines, i recall a guideline stating that when you introduce an acronym into your text, the first time used should include the full name written out such as Read Only Memory (ROM) before you consequently use the same term, ROM, again in your article.

 

the bottom line, please feel free to paraphrase this concept as i'm sure i'm not the first to conceive of this idea.

 

as for transformer types... yes, a Z is much different than a ZW, but as far as being out of alphabetical order, from the context in which the acronyms are used (e.g. "...a ZW transformer", "i might think about upgrading your power to a KW or ZW", etc), listing them all under the heading of transformer might not be as obscure a reference as you might think.

Consider it stolen, and thanks for the clarification on the Z, have added it.

 

Dave45681, Thanks for the link and info on the Z, will check it out and add your others to list.

 

Gilley@N&W, Got your additions, thanks. I had added MU earlier and that 'other term' (just for Rich) will add the others. Thanks!

My thinking is the same as yours, but I also think it would be nice to have a list of transformers somewhere for reference. Maybe another list? Still thinking...see the smoke?

I think among train guys ZW means the iconic postwar version much like a VW Beetle among car guys conjures up the original.

If it's that confusing we can just say ZW-transformers made by Lionel including the postwar ZW, the ZW blah blah blah introduced in XYZ and the ZW-L introduced... 

I think we're smart enough to figure it out.

baltimoretrainworks,

I agree, just letting them know that a ZW is a transformer is all this list needs to do. If anyone wants more info they can search it out now that they know what it is.

 

I was going to look up the wattages I didn't have for some of the transformers, but while trying to test my formatting it went to the moderators again... I turned myself in...

 

NelsonW,

Had NO & NC on the list, but tried to re-work the definitions from your post.

 

Thanks again to all!

i hope if you ever referenced the NLOE or RMLI groups, you would apply the guideline of spelling out the whole name at least once.  there are likely thousands of club and museum acronyms well known only to a handful of people when put on a global scale.


True.  Though they came to mind because of my participation in their programs, that is not the only reason I listed them. 

 

There are many others (certainly within the US, and probably a few abroad), but these came to mind due to threads I have noticed over the years. 

 

The members who post the threads pretty much always spell out the organization name within their posts, I think , but it's not practical to spell out in the thread title.

 

I'm not sure this one is official, but I can't imagine how none of us suggested it yet:
