Terms, Abbreviations, and Meanings at

As you view some the information provided on, you may encounter certain terms or abbreviations. Many of them may be self-explanatory or overtly obvious. Others, however, may not be and/or they may be the author’s own creation. In some cases, words, phrases, or abbreviations may be linked to site tags or categories. In the descriptions of some products, especially those imported into the site, some of the abbreviations may be expanded for you. In almost all cases where an algorithm was used to expand an abbreviation, you will typically see a term = value pair where the term represents a word or an abbreviation and its meanings is the word or phrase that follows an equal mark. Example: pLFW = Plastic Low-Flange Wheels. The term is “pLFW” and its meaning is “Plastic Low-Flange Wheels”. Below are several sections that identify most of the vernacular used on this website.

Product Conditions

In the shop, many products are listed from time to time. I use the following terms to describe the conditions of the products that are listed on this site. This site uses technology that posts products on this site to eBay and possibly other marketplaces. Those other marketplaces my use different terms for formal conditions. Attempts to match condition between marketplaces may be made, but it all cases, the conditions provided on this site are the most accurate. Conditions have a ranking value as well and many times may be the starting point of the established price or value of an item. For instance, New has a ranking value of 100% which represents that the item is Factory New and believed to be in its best possible condition. The Good condition has a ranking value of 60%. So, you might see a used product listed in the shop that has a starting price of 60% of its original manufacturer’s suggested retail price. Example: A new Bachmann Steam Locomotive that is NEW might have a retail price of $259.99 while that same used locomotive may be in Good shape with a price of $155.99 (60% of the $259.99 retail price of the new one). Be aware, that there is a possibility for an item to be Better Than New.

Conditions Meaning Rank Value
Enhanced This condition is typically a modifier of other conditions wherever 2 conditions can be stated.  When it appears where only 1 condition can be stated, then the previous condition was probably not known, and the item was found to have been enhanced or it was enhanced by this website’s owner.  An enhance by the owner can very easily make an item worth more than it was originally when it was first manufactured. 125%
