Thoroughbred Racing Associations
of North America
Significant TRA contributions to the industry include the formation of its subsidiaries.
Thoroughbred Racing Protective Bureau
In 1946, the TRPB, a subsidiary of the TRA, was formed to preserve integrity and security in racing.
Subsidiaries of the TRA and The Jockey Club formed Equibase in a 1990 partnership to accumulate the racing data necessary for the unfettered growth of simulcast wagering.
