Parramatta Metro Station Open Day with close-up views of TBM Dorothy - Sydney Metro West Project

In this video, I get up close and personal to TBM Dorothy whilst it was traversing the Parramatta Metro Station Box. You'll learn how these Hard Rock TBMs work from an expert within Gamuda and Laing O’Rourke who are the principal contractors for the tunnels between Sydney Olympic Park and Westmead. You'll also learn about Tunnel Nozzles, Thrust Frames, and how the cross-passages that connect the twin tunnels are created.

However, sometimes the information isn't available, so I'll use my railway knowledge and insight to explain something to the best of my ability. If accuracy is important, do check the comments, as other viewers will often pick up on things I've missed or any mistakes made. Also note that for older videos, things may change over time, causing some of the information to become out of date. Copyright The vast majority of footage is my own, but I will occasionally use photos and videos from other sources to explain ideas more clearly and accurately or to provide comparisons with other transport systems. In US, Australian and international copyright law, this is considered to be "fair use", and I'll always add an image credit in the video, and where possible, link to the original material in the description.
