Crossrail in London has been called one of the largest railway infrastructure projects in Europe.
Essentially, Crossrail is a new, high-frequency and high-capacity rail network comprising 136 km of track that will supplement the London Underground (which is nearing the limit of its capacity). The network will connect Reading to Abbey Wood (a suburb in the southeast of the capital), delivering a higher frequency service of up to 24 trains per hour during peak periods. Crossrail will also connect Heathrow Airport to the Eurostar high-speed line, which travels to mainland Europe via the Channel Tunnel.
With a total estimated cost of around 15 billion pounds, the initiative is confirmed to be Europe’s largest and most ambitious public works project of all time. Despite some teething problems, the construction of the new network is well under way and the central section is expected to enter service by 2018, as per schedule.
Working away in this dark and cluttered complex of narrow, muddy tunnels up to 40 metres underground are a number of Dieci concrete mixers and dumpers, agile machines that are ideally suited to operating in such conditions.
The dumpers, with a load capacity up to 7 cubic metres, quickly transport excavated material to conveyor belts, preparing the tunnel for subsequent strengthening operations that involve lining the walls with sprayed concrete.
The spraying nozzles are themselves fed by Dieci truck mixers with a production capacity of 5 cubic meters per hour, sufficient to keep pace with the eight giant cutterheads that dig 24 hours per day, 7 days per week.
Thanks partly to Dieci machines, the Crossrail project is entering its final stages. Nevertheless, consultations are already underway for the construction of Crossrail 2, an additional rail link on a on a north-south axis which, if approved, will begin construction in 2019 and open in 2033!
