The 125-metre-long tunnel boring machine - named Elizabeth after the 19th century philanthropist Elizabeth Cadbury - was launched near the Warwickshire village of Water Orton in March 2024. It arrived at Washwood Heath this morning.
Two identical machines were used to dig the 3.5-mile long Bromford tunnel that will carry high speed trains under the M6 and eastern outskirts of the city, with the first one – Mary Ann – breaking through earlier this year.
