Contract CR112 has made some headway since the arrival of the Tunnel Boring Machines (TBMs) at the site. Two TBMs will be used to bore the twin tube tunnels towards Serangoon North station. After a public name voting process, the TBMs are to be named Artemis & Valkyrie. Parts of the first TBM were lowered into the launch shaft on 7 December 2024 and the tail shield was lifted in on 13 December 2024.

Recently, German tunnel boring machine (TBM) manufacturer - Herrenknecht - uploaded several images of the machine numbered S-1365 onto its website. The TBM will be used for contract CR202 to construct the large diameter single bore tunnel through the Central Catchment Nature Reserve, connecting Cross Island Line (CRL)'s phases 1 and 2. The contract, won by a joint venture between Obayashi & Shanghai Tunnel Engineering Co, was the first of several CRL2 contracts to be awarded.
