Modifications on Hong Kong trams began in 1974, with adoption of fareboxes in place of conductors (except trailers until they scrapped) and re-position of the staircases. The period of class distribution has gone.
1974年電車進行大規模翻新，隨著引入收費錢箱和更改樓梯位置，象徵沿用多年的售票制度 (直到拖卡退役為止) 和等級制度成為歷史。
In early refurbishment period, there are different combinations of the trams on their staircase placement. The coloured stripes on tram 15 were designed to make trams more conspicuous in traffic.

In late 1973, trams are painted in jade green in place of its original dark Brunswick green, the striped sun visors (at the front gate afterwards) were also a signage for other vehicles. The rearside slope fleet numbers might have implemented at the same time.
