When the TA was reconstituted in 1947, 585 (Edinburgh) Field Squadron, RE was formed as an independent unit assigned to 155th (Lowland) Independent Infantry Brigade, but in 1950 it was absorbed into 124 Field Engineer Regiment, RE, the divisional engineers of 52nd (Lowland) Division.
In 1961, 585 and 586 Field Squadrons merged with 432 Light Anti-Aircraft Regiment, RA to form 432 (City of Edinburgh) Corps Engineer Regiment, RE [REF].
