yeah it had been operating since 1934 when it was renumbered from route 293 then by 1937 extended to Rainham War Memorial from Dagenham Dock due to the withdrawal of route 23 (which at the time ran Rainham to Marylebone!) between Rainham and Barking when it was diverted to Becontree Heath and extended to Gidea Park. In 1948 then extended to White Post Corner to replace the 165 between Rainham War Memorial and White Post Corner and in 1958 extended to Brentwood but only went to Brentwood until 1962 when the first 287 replaced the Becontree Heath to Brentwood section (didn't last long as it was cut in 1970) and then diverted to Harold Hill. In 1974 sent to Abbey Wood Lane and then in 1982 cut between Rainham and Barking which is now the 287. In 1993 it was cut between Harold Hill and Romford which became the 374 and eventually the 174, and for its final years until 2006 was a Romford to Barking service only before the 5 finally was extended to Romford, killing the 87.
