Cityrail have introduced Marshalls on Town Hall platform 3, as detailed in
this SMH report. This is an attempted solution to the capacity limitations on the Western and lower Northern Lines which run through this platform with limited space for intending passengers. A lot of the problem has been and remains people trying to board impeding people trying to get off. The reality is that Cityrail encourage this behaviour by blowing the whistle or playing the "Stand clear, doors closing" message while people are still trying to get off. This is an unprofessional and unacceptable practice which remains to this day. It no doubt contributes significantly to the low level of regard Cityrail is held by Sydneysiders.
This practice must end, forthwith!
