The construction of a speedway track at Brough Park began in early 1929, under the supervision of Lindon Travers.

[5] The team in 1938 was coached by former rider Gordon Byers and consisted of four Canadians, a season that saw the Diamonds nickname first used.

After the war, the team raced as Newcastle Brough in 1946 before Jeff Lloyd topped the league averages in 1947 for the Diamonds.

Under Mauger's leadership the Diamonds thrived, winning the club's first major trophy by sealing the 1964 league title.

[12] The 1967 and 1968 seasons were one of the rare occurrences where two of the greatest riders of all-time rode for the same team, although Olsen was in his early part of his career at the time.

[14] Brian Havelock and Tom Owen won the National League Pairs, held at Hyde Road on 17 May.

[15] The following season they won the double of National League title and Knockout Cup, in addition to winning the fours.

Tom Owen then topped the averages for three consecutive years in 1977, 1978 and 1979 becoming arguably the National League's leading rider during the period.

[17] The Diamonds moved up a division to compete in the British League during 1984 but due to financial issues, the promoters Ian Thomas and Robin Stannard did not enter a team for 1985.

[18] After missing 1985 they were brought back by Stannard and renamed the Newcastle Federation Specials for the 1986 National League season.

Team changes for 2000 saw the signings of Bjarne Pedersen and Andre Compton and together with Jesper Olsen they steered Newcastle to their first league title for 18 years.

After the 2019 season Rob Grant and former Stoke Potters promoter Dave Tattum took ownership of the club.

[23] Grant also cited his other business ventures, finances, and mental health as reasons to close the club before the completion of the league season.
