Following refurbishment in 1983, the fleet saw continued use; primarily on the Liverpool Street to Southend Victoria line, but also on the London, Tilbury and Southend line. From 1986, a few trains were repainted in Network SouthEast livery. By 1990, however, the class had been displaced from the LTS route by Class 310 trains, themselves cascaded from the West Coast Main Line following introduction of new Class 321/4 trains, supplemented temporarily by Class 317 trains. The Class 307 trains did not last much longer on the Great Eastern route, following the introduction of the new Class 321/3s.
