Standards
Standards for condition and grading have been developed by TCA that are widely accepted by individuals, websites, and auction houses. These include condition codes for original trains, for train paper, for restored trains, and for reproduction trains. These condition standards, together with the rarity of the item, will help to determine the dollar value and the collectability of a particular train or accessory.
Publications
TCA issues three publications during the year, the Train Collector Quarterly , the National Headquarters News, and the e*Train . Other organizations reference TCA and the York Meet in their publications and websites. Examples are Collectors Weekly, the Toy Train Paper and Memorabilia Group and Tandem Associates
Education
Divisions and Chapters of TCA host local train meets or train shows on a schedule throughout the United States where members may buy, sell, trade trains, or just enjoy the fellowship of collecting. Most shows are open to the public and may include educational segments, kids activities, and train doctors who can repair trains. The most prominent show, the York Train Meet, sponsored by the Eastern Division of TCA, is held over a three-day period twice a year in April and October in York, Pennsylvania. This show has 2000 tables of trains, large operating train layouts, and is open to TCA members and their guests. Some local divisions and chapters assist the Boy Scouts of America with the Railroading Merit Badge. Information about the Central Indiana Chapter.
