SRL Tunnel Boring Machine Named in Honor of Isolde’s Groundbreaking Legacy
A major milestone has been reached on the Suburban Rail Loop East project with the naming of one of its tunnel boring machines (TBMs) in honor of Isolde, a pioneering figure in the global tunnelling industry whose groundbreaking career continues to inspire a new generation of construction professionals.
Known as “TBM Issy,” the machine celebrates the achievements of Isolde, who made history more than two decades ago by becoming the world’s first female tunnel boring machine pilot. Today, she remains at the forefront of major infrastructure delivery, leading tunnelling operations on the Suburban Rail Loop East project and overseeing construction of the twin tunnels between Cheltenham and Glen Waverley.
The recognition is more than symbolic. It reflects the growing focus within Australia’s construction and infrastructure sectors on diversity, inclusion, and expanding opportunities for women in industries that have traditionally been male dominated. Through both her technical leadership and advocacy work, Isolde has become widely respected not only for her engineering expertise but also for her efforts to encourage greater female participation in construction and tunnelling careers.
As part of her current role on SRL East, Isolde leads tunnelling crews for Suburban Connect, including what is believed to be the world’s first all-women TBM crew. The initiative represents a landmark moment for the international tunnelling industry and demonstrates how large-scale infrastructure projects can help reshape workforce participation in engineering and construction.
Speaking about the honor, Isolde expressed pride in being associated with such a significant project and the broader initiative behind the TBM naming program.
“I’m absolutely thrilled to be a part of this incredible project and this history-making initiative, which I hope will encourage many more women to join the industry,” she said.
The Suburban Rail Loop East project is one of Australia’s largest transport infrastructure developments and will transform connectivity across Melbourne’s southeastern suburbs. Once completed, the new rail link will connect major employment, education, healthcare, and residential precincts, helping reduce travel times while supporting long-term population growth and urban development.
At the center of this ambitious undertaking are eight massive tunnel boring machines that will excavate approximately 26 kilometers of twin tunnels between Cheltenham and Box Hill. Four of those TBMs will work on the section managed by Suburban Connect, constructing 16 kilometers of tunnels between Cheltenham and Glen Waverley.
The TBM naming initiative was designed to recognize influential women from a wide range of fields, including health, community leadership, education, the arts, and construction. Involving local communities directly in the process, Grade 1, 2, and 3 students from seven primary schools located along the SRL East alignment participated in selecting the names. Students voted from a shortlist honoring women who have made meaningful contributions to society and inspired others through leadership and innovation.
The initiative provided a unique educational opportunity for students to engage with one of the state’s most important infrastructure projects while learning about influential female role models from diverse backgrounds.
Joining TBM Issy on the Cheltenham to Glen Waverley section are three additional tunnel boring machines, each named after women recognized for their impact in different areas of Australian society.
One of the machines is named Aayushi, in honor of Aayushi Khillan, a health advocate and founder of the social enterprise Body Buddies. Her work has focused on promoting positive body image and wellbeing among young people, helping create supportive environments that encourage confidence and self-acceptance.
Another TBM has been named Belinda, recognizing Belinda McKenzie, who became the first woman to drive Melbourne’s historic Puffing Billy Railway steam train. Her achievement represented an important breakthrough in a field traditionally dominated by men and highlighted the increasing opportunities available to women in transport and engineering-related industries.
The third machine on this section is named Muriel, honoring Aunty Muriel Bamblett, a respected Elder connected to the Yorta Yorta, Dja Dja Wurrung, Taungurung, and Bunurong peoples. Aunty Muriel has dedicated decades to supporting Aboriginal children, families, and communities through advocacy, leadership, and social programs that strengthen cultural identity and wellbeing.
On the Glen Waverley to Box Hill section of SRL East, four additional TBMs will continue the theme of celebrating influential women from diverse sectors.
One machine will carry the name Alice, recognizing Australian music producer and artist Alice Ivy for her contributions to contemporary music and creative arts.
Another will be named Bich Cam, after Bich Cam Nguyen, founder of the Australian Vietnamese Women’s Association. Her work has played an important role in supporting migrant communities and empowering women through education, social support, and community engagement initiatives.
A further TBM will be known as Elizabeth, honoring chef, educator, and author Elizabeth Chong, who has significantly influenced Australia’s culinary culture and promoted multicultural understanding through food and education.
The final TBM will be named Hacia, in recognition of Hacia Atherton, founder of Empowered Women in Trades. Her organization supports women pursuing careers in skilled trades and construction by providing mentoring, training, and advocacy aimed at increasing gender diversity within the industry.
Together, the eight TBMs represent far more than engineering equipment. They symbolize the values of leadership, resilience, innovation, and inclusion that the Suburban Rail Loop project aims to promote throughout its construction journey.
The naming program also reflects a broader cultural shift occurring across the global construction industry, where major infrastructure projects are increasingly being used as platforms to encourage workforce diversity and inspire future generations. By highlighting the stories of women who have broken barriers in their respective fields, the initiative seeks to challenge stereotypes and demonstrate that careers in engineering, construction, transportation, and leadership are open to everyone.
As tunnelling progresses beneath Melbourne’s suburbs, the TBMs and their crews will play a crucial role in shaping the city’s future transport network. At the same time, the women whose names they carry will continue to inspire communities, students, and workers involved in the project.
For many observers, the naming of TBM Issy stands out as a particularly meaningful tribute. Isolde’s journey from becoming the world’s first female TBM pilot to leading one of Australia’s most significant tunnelling operations demonstrates how determination, skill, and leadership can transform industries and create new opportunities for future generations.
Through these machines and the stories behind them, SRL East is not only building tunnels beneath Melbourne — it is also helping build a more inclusive future for Australia’s infrastructure and construction sectors.
