The Greensburg location was closed in 2000 following the decline and eventual vacancy of the Greengate shopping mall where it was located. Locations followed in Greensburg, Johnstown, Harmar Township, Moon, and West Mifflin (all in Pennsylvania). The first opened in New Castle, Pennsylvania, in June 1990. The company changed the name to Ladbroke at the Meadows and opened a series of off-track betting parlors named Ladbrokes. Williams purchased the track in 1986, and subsequently sold it to England-based Ladbroke Group PLC in 1988. The track used a marketing campaign to promote the services with the slogan 'Every 16 minutes, the place goes crazy', alluding to the typically quick pace from race-to-race at harness tracks. The telecast also included a half-hour preview show hosted by track announcer Roger Huston. In conjunction, the MRN telecast each day's live races and was distributed to local cable providers. Call-A-Bet allowed users to create individual wagering accounts and phone-in wagers for races.

The Meadows introduced two significant technological advancements in 1983: Call-A-Bet and the Meadows Racing Network (MRN). In 2009, the Pennsylvania Historical and Museum Commission erected a historical marker at The Meadows to note Miller's historic importance. Miller's imprint still exists on the track today, with The Meadows most prestigious race bearing his name (the Delvin Miller Adios Pace for the Orchids), and a statue of his famous sire Adios located at the track's entrance. The Washington Trotting Association was purchased in February 1973 by a group including famous trainer/driver Delvin Miller. The track opened on June 28, 1963, and was operated by the Washington Trotting Association.

In November 1962, ground was broken for the first parimutuel horse-racing track in Western Pennsylvania.
