M set train on t4 line

Hi everyone. There is 2 days, which has m sets on t4 line. It is operating from the city circle to hurstville when the line between central and bondi junction is not closed for trackwork, which is quite weird. M sets are also my favourite trains, so i am happy for that, but there might be some power issues because someone said m sets were first introduced on the t4 line, but was withdrawn from the lone due to power issues. I hope this does not happen. Unicorn.123sl🦄 (talk) (she, her) 09:50, 14 July 2022 (UTC) Posted on 14/07/2022 at around 7:50pm
