Buses, Trains and Taxis: What Transport Advertising Can Do For a Small Business

Part of our series on growing your brand without a giant budget.

When people picture Out of Home advertising, they tend to picture a roadside billboard. That is a fraction of the picture. UK OOH hit a record £1.44 billion in 2025, and a large and growing share of that sits on the transport network: buses, the Underground, rail and taxis, all moving past, and carrying, millions of people every single day. Each of these environments works differently, reaches a different audience, and suits a different brief. Here is what each one actually offers.

Buses go where people go

4.08 billion local bus passenger journeys were made across Great Britain in the year ending March 2025, according to the Department for Transport’s annual bus statistics, with local buses covering around 1.25 billion service miles over the same period. That scale is not evenly spread. Brighton and Hove recorded 154 local bus journeys per head of population in that year, the highest of any local authority outside London, against an England-outside-London average of 37, so the opportunity varies considerably by market and is worth checking against your own target area rather than assumed.

Bus advertising is widely considered an excellent entry-level format for a business new to Out of Home. It reaches two distinct audiences at once: the passengers riding inside, and the much larger street audience of pedestrians, drivers and shoppers who see the bus moving through its route. Key formats include full wraps, mega rears, passenger panels, streetliners, and internal and external panels, across both single and double-deck vehicles, which means there is a genuine range of entry points depending on budget.

London Underground: the biggest OOH contract in the world

The Underground network is genuinely enormous as an advertising proposition. Transport for London’s rail advertising contract, now held by Global, covers 272 London Underground stations and more than 120,000 Tube car panels, alongside London Overground, the DLR, trams and the Elizabeth line. It has been widely reported as the largest single Out of Home advertising deal in the world, believed to be worth around £1 billion over eight years.

For an advertiser, the practical appeal is dwell time. Commuters wait on platforms and in corridors, and that waiting creates a genuinely captive moment of attention that few other environments can match. Tube Card Panels deliver that strong dwell time and work particularly well for direct response activity, while Lift and Escalator Panels and 4, 6 and 12-sheets act almost like noticeboards across the network, building high cover and frequency. At the premium end, full platform and corridor domination is available for a brand that wants to own the entire environment, not just a single panel within it.

Rail and metro: reaching commuters beyond the capital

Rail’s reach stretches well beyond London. Office of Rail and Road figures show 1.73 billion rail passenger journeys were made across Great Britain in the year to March 2025, up 7% on the year before, a genuinely sizeable and growing audience of commuters and leisure travellers on the move.

Rail and metro formats cover static frames through to premium digital screens, Train Card Panels that deliver the same strong dwell time as their Underground equivalent, Ticket Gateways, and Station Digital Screens at major termini. It is a desirable audience for any brand targeting travellers with disposable time and attention on their hands, and the format range means a campaign can flex from a modest static placement up to a large-format digital takeover depending on budget and ambition.

Taxis: the premium, human-driven layer

Taxis sit apart from the rest of the transport network. London’s licensed black cab fleet has fallen by more than a third over the past decade, from around 22,500 to roughly 14,500, a genuine industry trend worth being aware of. What remains, though, is a premium, city-centre-focused, human-driven format: full liveries and superside panels that move through exactly the dense, high-footfall areas where many advertisers most want to be seen, carrying a strong association with trust and professionalism that other transport formats do not offer in quite the same way.

Choosing the right mix for your brief

None of these formats compete with each other so much as complement one another. Buses suit a business that needs broad, repeated local visibility on a modest budget. The Underground suits a brand chasing genuine scale and dwell time in the capital. Rail suits anyone targeting commuters and travellers in cities beyond London. Taxis suit a brand that wants a premium, concentrated presence in a specific city centre. As with the wider OOH booking process, the right starting point is always a clear brief covering your objectives, audience, geography and budget, so that whoever is planning the campaign can match the format to what you are actually trying to achieve rather than working backwards from whatever happens to be available.

Your transport advertising checklist

• A clear view of which audience you are chasing: passengers, the street audience around a vehicle, or both
• Your target geography checked against real local data, since reach and usage can vary enormously by city and even by local authority
• A realistic sense of budget against format: buses as the accessible entry point, Underground and premium taxi liveries at the higher end
• A decision on whether dwell time (Underground, rail) or movement and visibility (buses, taxis) matters more for your objective
• A brief that states your objectives, audience, geography, timing and budget clearly enough for a media owner or agency to match you to the right format
