Question: When did trolleys stop running in the city where Polarsets formed?

full_context: Document 1: Telegram messenger: By the 1960s the number of telegrams being delivered had dropped to 10 million, and in 1976 only 844 were delivered. Consequently the Post Office took the decision in 1977 to abolish the service. The service continued for a few years and was briefly operated by British Telecom after it split from the Post Office. British Telecom announced on 19 October 1981 that the telegram would be discontinued, and it was finally taken out of service on 30 September 1982 after 139 years in the United Kingdom.
Document 2: Melbourne: Melbourne has an integrated public transport system based around extensive train, tram, bus and taxi systems. Flinders Street Station was the world's busiest passenger station in 1927 and Melbourne's tram network overtook Sydney's to become the world's largest in the 1940s, at which time 25% of travellers used public transport but by 2003 it had declined to just 7.6%. The public transport system was privatised in 1999, symbolising the peak of the decline. Despite privatisation and successive governments persisting with auto-centric urban development into the 21st century, there have since been large increases in public transport patronage, with the mode share for commuters increasing to 14.8% and 8.4% of all trips. A target of 20% public transport mode share for Melbourne by 2020 was set by the state government in 2006. Since 2006 public transport patronage has grown by over 20%.
Document 3: New Haven, Connecticut: The New Haven Division buses follow routes that had originally been covered by trolley service. Horse-drawn steetcars began operating in New Haven in the 1860s, and by the mid-1890s all the lines had become electric. In the 1920s and 1930s, some of the trolley lines began to be replaced by bus lines, with the last trolley route converted to bus in 1948. The City of New Haven is in the very early stages of considering the restoration of streetcar (light-rail) service, which has been absent since the postwar period.
