First TBM Used in Moscow Metro Project Starts Operation

The first tunnel boring machine (TBM) used to build a Moscow metro line recently started operation.

Contracted by China Railway Construction Corporation Limited (CRCC), a new 6.5-kilometer section of the metro in the southwestern part of the city will serve a building material market and connect to the Moscow Large Circle Line – a traffic artery in the city.

The 6.28-meter diameter TBM will be used in the construction and it is expected that by the end of March three more will be operating at the same time, greatly improving construction efficiency.

Passengers will be able to transfer to the circle line when the new line is completed, which will greatly relieve traffic pressure and make travel easier.
