Lokomotiv Gorna Oriahovica

The club was established in 1932 as RSC - Railway Sports Club (Bulgarian: ЖСК - Железничарски спортен клуб) by the railway workers at the Gorna Oryahovitsa railway station, a major railway junction in northern Bulgaria. In 1944 RSC merged with SC Borislav and was later renamed to RSC Borislav. The team finally became known by their current name Lokomotiv in 1945. Lokomotiv's best performance in the Bulgarian Cup came in 1947, when they lost to eventual winners Levski Sofia in the semi-final, a feat, which they would achieve again in 1987, but again losing to cup holders Levski Sofia. In the 1962–63 season, they won the B Group title, earning promotion to the A Group for the first time in their history. In their maiden top-tier season, Lokomotiv endured a difficult 1963–64 campaign. The team eventually finished the season last and was relegated back to the B Group after a single season.

In the 1986–87 season, Lokomotiv ranked second in the B Group and won promotion to the A Group after a 23-year absence. This began the golden age for Lokomotiv as the team spent eight consecutive seasons in the top division before being relegated in 1995. During the 1990–91 A Group season, Lokomotiv's forward Ivaylo Yordanov finished as the leading goalscorer of the A Group with a total of 21 goals and was later transferred to Portuguese club Sporting C.P..

After 21 years of absence from the top flight, in the 2015–16 B Group, Lokomotiv finished third in the final league table and was one of the clubs approved and promoted to the newly restructured Bulgarian First League, following the adoption of new licensing criteria by the Bulgarian Football Union. The long-awaited return to the elite for Lokomotiv proved to be challenging, as the team spent the majority of the season competing in the relegation zone. Lokomotiv was eventually relegated after one season spent in the top flight.

After four seasons in the Second League, Lokomotiv were then relegated to the Third League at the end of the 2020/2021 season. After three seasons in the third level, Lokomotiv earned promotion back to the Second League in 2024.
