Since 2012, more than $20 billion has been directed toward the construction of Crossrail. Approximately 10,000 people work on the project at over 40 sites around the city.
Once it opens in late 2018, the system will be named after Her Majesty, Queen Elizabeth.
Crossrail says the goal of the project is to expand London's public transportation while also simplifying the process of getting around.
In practice, that looks like wide-open spaces with minimal visual clutter. People will be able to focus on reaching their destination.
But that doesn't mean the stations will be boring. Each one will pay homage to a piece of British history in its design.
The new Paddington station, for example, will honor the original Paddington station originally built in 1854 for steam locomotives.
Meanwhile, the Farringdon station will draw inspiration from the country's trading history among blacksmiths and goldsmiths.
Each station is also completely handicap-friendly, as there are no steps connecting them to the street. Instead, they all use a system of ramps, escalators, and elevators.
Ticketing centers are designed to move people more quickly. Crossrail is building multiple entrances for every station with ticket halls at each one.
Once passengers venture underground, they'll come upon 800-foot platforms that accommodate Crossrail's new 650-foot long trains.
2018 can't come soon enough.
