HKT 12: Lars F. Richter Photo (CSL, 3-APR-1989, Kennedy Town Loop)
The 1987 Trams, under the mass refurbishment, were new-built underframes and bodies in place of the dismantled old bodies. The bulkhead structure and removal of the lifeguard tray & gate are then the miniature of the present cars. Before the old bodies gone they are in normal service with the 1986/87 Trams, as shown below.
Special thanks to Julian for valuable photos
Tram 12 was the first 1987 car which replaced the gap when the original 12 went to Canada.
