Central Line History: From ‘Twopenny Tube’ to Crossrail Connection

The Central line is London’s spine. Stretching 46 miles from Ealing Broadway in the west to Epping in the east, it carries more passengers than any other line on the Underground — around 280 million journeys a year. But the route you ride today bears almost no resemblance to the modest railway that opened beneath the streets of the City in 1900. The Central’s story is one of bold engineering, wartime improvisation, ambitious post-war expansion, and an unexpected reunion with its 21st-century neighbour, the Elizabeth line.

This is the history of a line that helped define modern London — and is still evolving today.

The Twopenny Tube: London’s First Electric Underground Railway (1900)

When the Central London Railway opened on 30 June 1900, it did something no underground railway had managed before: it charged a flat fare of two pence for any journey along the route. That single pricing decision earned it its famous nickname — the Twopenny Tube — and made it an instant hit with Londoners who had previously navigated a bewildering patchwork of different fares on steam-hauled underground lines.

The original route was a clean east-west corridor running from Shepherd’s Bush to Bank, with thirteen stations threading beneath Oxford Street and the City. Crucially, it was fully electric from the start — the first deep-level ‘tube’ railway in the world to operate electric traction rather than steam. Passengers accustomed to the gloomy, smoke-filled atmosphere of the Metropolitan and District lines found the Central London Railway a revelation: clean, fast, and brightly lit.

The locomotives, supplied by American companies General Electric and British Thomson-Houston, were powerful but caused something of a crisis. Vibrations from the early engines were so severe that residents along Cheapside petitioned against the railway, and the original locomotives were quickly replaced with a lighter multiple-unit electric system — one of the first practical uses of this technology anywhere in the world.

📍 Did you know? The original Bank terminus was called ‘City’ — it was renamed Bank in 1933 when the network was reorganised under the newly formed London Passenger Transport Board.

Going Underground with the Map: 1908 and the Power of Design

By 1908, the Central London Railway had joined a commercial alliance with five other underground companies to promote the network as a unified whole. The result was the first Underground map — a geographical diagram that showed all six lines on a single sheet. The Central appeared as a thick red stripe cutting straight through the middle of London, and that visual identity has remained unchanged for more than a century.

Harry Beck’s famous schematic map, introduced in 1933, transformed the Central into something even more iconic. On Beck’s diagram, the Central line’s east-west axis became a near-perfect horizontal, anchoring the entire map and making it instantly legible. Beck’s design was a stroke of graphic genius — and the Central line’s geography, running almost due west-to-east, made it the natural backbone around which the rest of the system was organised.

Wartime Below Ground: The Tunnels That Saved Lives

During the Second World War, the Central line’s tunnels became something far more than a commuter railway. Sections of the partially built eastern extension — which had not yet opened to passengers — were requisitioned by the government and converted into a vast underground factory complex.

The tunnels between Leytonstone and Gants Hill were taken over by Plessey Company Ltd, which used the space to manufacture aircraft components for the war effort. Workers descended in purpose-built lifts and spent their shifts in the tunnels, producing components for Spitfires and other aircraft. At its peak, the operation employed around 2,000 people working in shifts around the clock.

Elsewhere on the network, deep-level shelters beneath Central line stations provided refuge for thousands of Londoners during the Blitz. Bethnal Green station became the site of one of the worst civilian disasters of the war — not from enemy action, but from a crush on the steps during an air raid alert in March 1943, in which 173 people lost their lives. A memorial at the station commemorates those who died.

The Great Eastern Extension: Postwar Ambition (1946–49)

The government had begun planning an ambitious expansion of the Central line in the late 1930s, but the war delayed everything. When the eastern extension finally opened in stages between 1946 and 1949, it transformed the line’s character entirely.

The new stations — Stratford, Leyton, Leytonstone, Wanstead, Redbridge, Gants Hill, Newbury Park, Barkingside, Fairlop, Hainault, Chigwell, Theydon Bois, Debden, Loughton, and Epping — doubled the line’s eastern reach and connected it to the former Great Eastern Railway routes into Essex. Suddenly, the Central line extended deep into the outer suburbs, carrying workers from Essex commuter towns directly into the heart of the City without a change.

The architecture of these stations is worth noting. Many of the new eastern extensions were designed by London Transport’s architect Charles Holden in a clean, Modernist style — particularly Gants Hill, which features a dramatically vaulted subterranean concourse inspired by the Moscow Metro, and Newbury Park, which was later listed for its distinctive bus shelter canopy.

• Gants Hill: Moscow-inspired underground concourse, now Grade II listed
• Newbury Park: canopied bus station designed by Oliver Hill, Grade II listed
• Hainault loop: the only circular section on the entire Underground network

The Western Reaches: Ealing, Ruislip, and Beyond

The western end of the Central line has its own distinct character. Beyond Notting Hill Gate, the line rises above ground at Wood Lane and travels through a series of suburban neighbourhoods before dividing at North Acton into two branches: one heading to Ealing Broadway, the other to West Ruislip via Greenford.

The West Ruislip branch, opened in stages between 1947 and 1948, incorporated former Great Western Railway tracks — making this section of the Central line unusual in running on mainline-gauge infrastructure rather than the narrower tube tunnels beneath the city centre. Trains on this section feel noticeably different from the cramped deep-level sections beneath Oxford Street.

Shepherd’s Bush and Holland Park remain two of the Central line’s most characterful stations. Shepherd’s Bush, now served by both the Central and the Overground’s Shepherd’s Bush station nearby, sits at the edge of one of West London’s most rapidly changing neighbourhoods. Holland Park’s station, tucked beneath the grand Victorian terraces of the same name, retains some of the original 1900 design elements beneath later surface changes.

Crossrail’s Arrival: The Elizabeth Line Changes Everything

For decades, the Central line was the east-west corridor for London travel. Then, in May 2022, the Elizabeth line opened — and the relationship between the two railways became one of the most interesting stories in London’s recent transport history.

The Elizabeth line runs an almost parallel route through central London, connecting Heathrow and Reading in the west with Shenfield and Abbey Wood in the east. At several stations — Liverpool Street, Bond Street, Tottenham Court Road — Central line platforms sit directly above or beside Elizabeth line platforms, with interchange between the two.

The effect has been significant. The Elizabeth line now carries passengers who might once have used the Central for journeys between, say, Paddington and Liverpool Street — and journey times on that corridor have fallen dramatically. Meanwhile, the Central has retained its role as the go-to line for Oxford Street, Holborn, Bethnal Green, and the deeper suburban east — stations the Elizabeth line does not serve.

The two lines have become complementary rather than competitive, and for visitors planning a day across London, understanding which to use for which journey is now an important part of navigating the city intelligently.

💡 Practical tip If you’re travelling between Heathrow and central London, the Elizabeth line is almost always faster than the Central. But for Oxford Circus, Notting Hill Gate, and anywhere east of Liverpool Street on the Central’s own branches, you’ll still want the red line.
