There are collectors in pretty much every hobby. These are the people who drive up prices of hard-to-find items like a first-issue Superman comic. Items that most people could care less about but they value because they're so hard to come by.

They help set standards and values, expend vast amounts of time detailing and listing historical facts about existing railroad prototypes and in general help to drive a level of professionalism into the hobby that otherwise might be missing. Model train collectors are a good thing, and the fact is that most collectors are also hobbyists - displaying their collections not in jewel cases or behind glass but in a Model Train layout of their own design.

Some of the model train companies, such as Lionel Trains, even sponsor collectors groups for their historic equipment. If you're interested in learning more about a particular type of train, there are probably clubs you can join.

One of the things these groups do is create standards by which equipment can be rated. The equipment is often rated separately from the packaging it came in, if the box is still intact, and those that are still in the original box, never having been removed, fetch the highest prices.

Model Train Grading

* NEW - In original condition, most likely never used or even removed from the package.

* LIKE NEW - This grade indicates that the model train is as good as new, but may have been used and removed from its packaging in the past.

*EXCELLENT - Excellent condition means there is no rust, dirt or damage but that the item has definitely been used.

* VERY GOOD - Some wear but no serious damage or rust.

* GOOD - There may be some slight scratches as well as normal wear but no rust.

* FAIR - Slightly damaged, worn and possibly scratched but still quite usable.

* POOR - Suitable only for parts and possible not working.

How Packaging Is Graded

* NEW - In the original condition, no damage or discoloration.

* LIKE NEW - May have a bit of wear but no major blemishes.

* EXCELLENT - Like-original packaging with only moderate wear, no repairs.

* VERY GOOD - May have some tears or damage possible non-original tape but complete.

* GOOD - Could be missing certain elements, noticable wear and possibly mildew damage.

* FAIR - Missing pieces, tears and discoloration are all likely.

* R - A replica, not the original packaging.

Knowing these grades and having some money to spend will give you a big headstart on collecting model trains. Pick your favorite era or brand and dive right in. Just keep in mind that a collection's value is in the eyes of the collector - it may not be the best investment!
