History of The OO Scale
OO Scale is the most popular standard-gauge model railroad track used to make model railways in the UK. OO Scale uses track that is 16.5 mm gauge.
Bing launched the OO scale in 1921 as “The Table Railway” with all the locomotives being powered by clockwork, the first electric power locomotives appeared in 1923. In 1932 Bing closed but the scale continued to be made by Trix. The Meccano Company launched a range of OO scale models named Hornby Dublo which continues to be the UK's most popular scale. The OO scale showed up for only 4 years in the United States when Lionel released its first models in 1938 lack of interest lead Lionel to discontinue the scale.
HO scale and OO scale run on the same track but the British models (OO scale) are larger then their American and European counterparts so they can not run properly on each others track.
Hornby Railways and Bachmann Branchline dominate the UK's market for OO scale over other scales simply by having more readily available starter sets and ready-to-run stock.
