SW5 Class 849 entered service in Melbourne on the 1 February 1940.
Following the success of SW6 Class 850 that had entered service in March 1939 as a prototype for future trams, trams 840 to 849 that were at that stage under construction as W5 Class trams were upgraded to include the sliding doors and metal framed windows that had been trialled on 850.
Leading a fairly uneventful life in day to day service in Melbourne, 849 was fitted with the multiple head and tail lights in September 1971.
849 was stored as one of the ‘ready-reserve’ fleet at Preston Workshops in 1998, and remained there until being donated to the Association by VicTrack, arriving at Haddon on 8 July 2008.
Initially sister tram 843 was going to be preserved by the MTPA with 849 destined to provide parts for 843’s restoration. On arrival at Haddon, it was determined that 849 was in better condition that 843, and so 843 instead was dismantled to provide the parts needed to return 849 to operating condition.
849 is currently under refurbishment at Haddon, and details of the work in progress can be found on its restoration page.
