Robbins' Crossover XRE TBM breaks  three world records again. From Robbins site:

`The 13.77 m (45.18 ft) XRE TBM set world records three times over, beating its own records in May and June with a set of records over the summer, including a best day of 32.4 m (106 ft), a best week of 178.2 m (584.6 ft), and a best month of 721.8 m (2,368 ft). Launched in March 2021, the machine bored 3.05 km (1.90 mi) on the Esme-Salihli Railway Tunnel as part of the Ankara-İzmir High Speed Railway Project for the TCDD. `
