The origins of train departure boards

As rail travel expanded in the 20th century, the increasing number of passengers brought a greater demand for clearer and more detailed information at stations. Departure boards began to include additional details such as platform numbers and service types. This evolution aimed to provide passengers with comprehensive information to navigate the expanding rail network effectively.

The advent of electricity further transformed these systems. Moving beyond manual updates, departure boards became more efficient systems powered by new technology.

The introduction of electric displays

The first motorised flip-board display was developed by the Italian manufacturer Solari di Udine and was first showcased at a railway station in Liège, Belgium, in 1956. A few years later, the displays began appearing in the UK, initially at Manchester Airport and later at several stations in 1962. These innovative displays quickly gained popularity, spreading to Europe and beyond, replacing older mechanical boards at stations.

These departure boards became known as flap displays. They were also called split-flap displays or Solari boards, after the company that created them. Solari boards had metal flaps with silkscreened information that were mounted on a wheel. Each wheel could hold up to 40 flaps. An electromechanical behind the board rotated the flaps, which made a loud clacking sound.

The signature sound of the flaps rotating became the board’s trademark, alerting travellers to the changing of information. They also offered increased visibility from a wide range of viewing points, which was invaluable in busy airports and train stations.

Early challenges and adoption

While the Solari boards marked a leap forward, they brought new challenges too.

At busy stations, staff used punch cards to update the display, each one was coded to trigger the right combination of flaps. This process was labour intensive, and often night shifts were required to manually cut and prep cards in response to service changes, including last-minute service changes or weekend rail replacement buses.

Maintenance issues were also a concern. The electromechanical nature of these systems meant that spills or moisture could lead to short circuits which disrupted the display’s functionality.

The rise of digital and electronic departure boards

In today’s digital age, train stations have embraced modern technology to ensure passengers receive information quickly and clearly. As a result, railway companies have adopted more advanced systems to meet the demands of fast-paced travel.

In the latter 20th century, many stations began replacing older mechanical departure boards with LED displays. These new systems offered dynamic, real-time updates that could be changed in seconds, making them far more efficient than the traditional manual boards.

The shift to digital screens

Digital technology changed how we share information. Static boards gave way to dynamic and scrolling displays that could provide instant updates.

Passengers could quickly check platforms, delays, or cancellations just by glancing up. This not only increased departure board efficiency, but also helped travellers find information quickly.

Behind the scenes, computer systems pulled real-time data directly from central control and fed it to the departure boards.

Integration with online apps and mobile devices

As digital systems became more advanced, departure boards began working alongside apps and online platforms. Today’s boards are powered by the same real-time data used for mobile apps, meaning passengers see consistent information whether they’re in the station or on their phone.

Rather than replacing boards, mobile technology supports them, allowing for updates to be mirrored across platforms and gives passengers peace of mind before even arriving at the station.

Real-time data and the passenger experience

It’s easy to overlook just how essential departure boards have become. For daily commuters, leisure travellers, and tourists, they provide clarity in busy stations.

As technology continues to move forward, these boards aren’t just getting smarter, they’re helping the entire rail network run more smoothly. From better communication to real-time updates, each advancement plays a part in shaping a more reliable and connected travel experience.

Technological advancements in departure boards

Modern departure boards are smarter, faster, and easier to use. They now offer many convenient features including:

• Increased accuracy as a result of integration with GPS tracking and cloud-based systems to give more accurate, real-time updates
• Easier viewing using multiple screens with full-colour displays to make them easier to read, even in busy stations
• Precise predictions of train arrival times, thanks to machine learning

The future of train departure boards

As train travel becomes more digital, so do the tools we use to navigate it. In 2023, the Elizabeth line tested new platform displays at Liverpool Street and Paddington stations to see how passengers respond to clearer, more detailed information.

Some screens listed four upcoming departures instead of three, while others added helpful routing info like “via Canary Wharf.” The trial also aimed to simplify journeys to Heathrow, making it clearer that all trains stop at Terminals 2 and 3, with easy connections to Terminals 4 and 5.

High-definition screens are also replacing older LED displays across the network. They’re easier to read and can update instantly, helping passengers stay informed, even when services change at short notice.

Innovations on the horizon

Looking ahead, new technologies could make departure boards even smarter and more personalised. Artificial intelligence is already starting to play a role. By analysing data on the stations, signals, track, curves, trains, and more, AI can help manage the station schedule.

In the future predictive AI analytics will anticipate changes in train schedules before they even happen. By analysing data on delays, faults, and weather, it could start predicting disruptions before they happen.

Enhancing accessibility and user experience

New live departure boards will aim to improve user experience for all passengers, including those with disabilities. Larger fonts, contrasting colourways, and simplified information will all make departure information clearer.

Looking ahead, digital displays will become more personalised and more connected to the wider travel experience. Whether through real-time smartphone updates or intuitive station signage, every improvement helps make rail travel more inclusive, efficient, and seamless.
