This decision also led to the relocation of the Rockingham station from the city centre to the outer edge in order to offset the additional costs of the Perth section. The original route included tunnels to bring the railway into the Rockingham CBD. As a trade-off for relocating Rockingham station to the outer edge, the State Government promised a light rail link to the Rockingham CBD. This was later revised to a Central Area Transit style bus service partly within a dedicated busway. As part of the work, the and Mount Henry Bridges were rebuilt.
