2025年的一项审计披露,新南威尔士州运输公司尽管知道严重过度拥挤,导致费用高昂的修补和服务中断,但仍批准了数量较少的火车。 A 2025 audit revealed Transport for NSW approved fewer-seated trains despite knowing about severe overcrowding, leading to costly fixes and service disruptions.

2025年审计发现,新南威尔士州运输公司知道南海岸线严重拥挤的情况,当时它批准了新的Mariyung火车,由于2+2座位布局,座位减少,每辆8辆火车的座位从864个减少到690个。 A 2025 audit found Transport for NSW knew about severe overcrowding on the South Coast line when it approved new Mariyung trains with fewer seats due to a 2+2 seating layout, reducing capacity from 864 to 690 seats per eight-car train. 尽管高峰列车容量超过135%,有些达到171%,但该机构没有制定一项解决过度拥挤问题的资金计划. Despite peak trains exceeding 135% capacity—some reaching 171%—the agency moved forward without a funded plan to address overcrowding. 这导致了费用高昂的合同变更,包括以28%的较高成本购买42辆额外运输车,以便在高峰时段将火车扩大到10辆汽车。 This led to costly contract changes, including purchasing 42 additional carriages at 28% higher cost to extend trains to ten cars during peak hours. 较长的火车不能使用悉尼所有地下平台,迫使一些服务在中央而不是邦迪交汇处终止,需要转移。 Longer trains cannot use all Sydney underground platforms, forcing some services to terminate at Central instead of Bondi Junction, requiring transfers. 审计批评了采购程序,认为采购过程没有考虑到座位减少和业务影响。 The audit criticized the procurement process for failing to account for reduced seating and operational impacts.
