The team over at Rail Engineer took a look at the phases of installing a Crossrail system and after the tunneling for the project is done, next come the concrete.
The team takes a look at how this concrete will be applied and the products will be used, including a concrete train:
The concreting train is a sophisticated mobile underground concrete batching factory, which is the reason for its significant length. Dry materials are loaded onto the concreting train, which then batches the concrete. At 465 metres long, this train plays a key role in creating the standard track slab. Refurbished and brought to the UK from France via the Channel Tunnel in August 2015, it will be based at Plumstead and used in the installation of standard track slab. At its peak production rate it will be able to install up to 250 metres of concrete track slab a day.
