The line is set to carry its first passengers across the capital in December 2018, travelling from Reading in the West to Abbey Wood in the east, and is expected to cost a total of £14.8 billion.
The new pictures give a glimpse of what passengers can expect from the station architecture.
Escalators and light fittings are being put in place, and each station is receiving its own bespoke elements – like a wall map of Soho in Tottenham Court Road and a Barbican-style ticket hall at Farringdon.
Julian Robinson, Crossrail Head of Architecture, said: “Crossrail is working with the best architects and engineers in the world to create a railway that builds upon the unrivalled heritage of London and its iconic transport network.
“As the project passes 85% complete, these new images highlight the progress being made to install the architectural elements that will soon become familiar to the hundreds of thousands of passengers who will use the Elizabeth line when it opens in December 2018.”
