The numbers look big, but they are standing still
Two point one billion pounds. That is the value of UK tickets Trainline sold in the six months to the end of August. It is a huge number. But it is also a problem. The figure represents zero growth. Absolutely none. For a technology company listed on the FTSE 250, one whose story has always been about rapid expansion and capturing the online market, a growth rate of nothing is a serious issue that raises immediate questions for its management and its shareholders.
The company has a story about this. It is a familiar one. Trainline’s management was clear in its trading update on 11 September where it placed the blame for the stalled sales figures. It pointed first to industrial action, naming the London Tube strikes as a particular drag on performance. Then it pointed at the government. The freeze on regulated rail fares, designed to help with the cost of living, directly limits the total value of the tickets that Trainline can sell. The final reason was the weather. The company’s update cited additional disruptions from periods of hot weather, a claim that suggests even the climate is now conspiring against its bottom line.
Unions, politicians, and the weather. It is a convenient list of culprits. Few would argue that Britain’s railways have offered a smooth service this year. The network is fragile. But for a technology firm whose entire proposition rests on digital efficiency and unstoppable growth, blaming the sun feels weak. It invites scepticism. It also forces a more fundamental question about the company itself, one that its executives are less keen to discuss publicly. Is the problem truly a handful of strike days and a temporary cap on prices, or does the real vulnerability lie within the very structure of Trainline's business, which relies on earning a small slice of a very large pie that has just stopped getting bigger?
How Trainline actually makes its money
That £2.1 billion is not Trainline's money. It is crucial to understand this. The figure is not revenue. It is not profit. It is simply the gross value of all the tickets the company sold for UK rail journeys in six months, a metric the City calls net ticket sales. Trainline is a digital shopkeeper. Its actual income, the money it uses to pay its software engineers, its marketing teams and its chief executive, is a small slice of that enormous number. This distinction is everything. It is the entire story. The company functions as an agent, earning a commission on the tickets it shifts on behalf of Britain’s train operating companies, a fee that is fixed in contracts negotiated years ago. Its success depends entirely on selling more tickets, or more expensive tickets, year after year.
When sales go flat, so does income. It is that simple. While the exact commission Trainline receives on any individual ticket can vary, their business model over the years has been built on an average commission of around 4 per cent from the UK consumer division. Apply that to the £2.1 billion in sales. The calculation suggests Trainline generated roughly £84 million in revenue from its UK platform in the half year. The problem is that this is the same amount it would have generated on the same sales volume last year. There is no growth. If sales had continued on their previous trajectory, for example growing by a modest 10 per cent, that £2.1 billion would have been £2.31 billion, translating into over £92 million of revenue. Stagnation has therefore wiped more than £8 million from its expected UK top line. This is a significant hole for a company of its size.
This model exposes a fundamental weakness. It is brittle. Trainline has very little control over the core product it sells. It cannot run more trains. It cannot prevent strikes. It cannot set the price of a regulated anytime single from London to Manchester. Its revenue is therefore directly hostage to the physical and political chaos of the British railway network. While its own costs, for things like technology investment and staff salaries, continue to rise with inflation, its ability to grow its income can be halted instantly by a union dispute or a government policy decision. The company is a sleek digital superstructure built on rattling, unreliable foundations. When those foundations shudder, the entire business feels the vibration directly on its bottom line.
An audit of the excuses
So are the excuses credible? Trainline points to three culprits. Strikes. The fare freeze. Hot weather. The company presents itself as a victim of forces beyond its control. It is an argument that requires scrutiny. It does not entirely convince.
Let's begin with the strikes. This excuse has merit. The period from March to August 2026 was plagued by industrial action. Analysis of union announcements shows a total of fifteen days of national walkouts by drivers in the ASLEF union and staff belonging to the RMT. That is a significant number. It is up from twelve in the same six months last year. Each one of those days represents a near total shutdown of the network, a day on which Trainline sells almost no tickets because there are almost no trains to ticket. The knock on disruption, with overtime bans and altered timetables on adjacent days, further suppresses passenger demand and therefore sales. People do not buy tickets for trains they do not believe will run. This is a real headwind. You cannot sell tickets for empty tracks.
The second reason is the fare freeze. This is a quieter, more corrosive problem for the company's growth model. The government's decision to freeze all regulated rail fares for another year means that the face value of a huge proportion of the tickets Trainline sells cannot increase, directly capping the cash value of the company’s percentage based commission. This policy was intended to help passengers with the cost of living. A side effect is that it strangles a key avenue of growth for Trainline. Even if the platform successfully encourages more people to travel by train, its revenue per passenger on these regulated routes is frozen solid. Growth can only come from selling more tickets, not from the price of each ticket rising with inflation as it normally would. The policy effectively severs the link between a rising cost base and a rising income, a toxic situation for any business.
Then there is the weather. The company's report mentions 'disruptions from hot weather'. This is the weakest pillar of the argument. It feels like an excuse thrown in for good measure. While there were indeed some speed restrictions on certain lines, particularly on the East Coast Main Line during a week of high temperatures in July, there was no repeat of the widespread, multi day network shutdowns seen in previous summers. The disruption was localised and temporary. It does not seem sufficient to materially affect a six month, £2.1 billion sales figure for the entire country. Blaming the summer sun for flatlining sales in places like Scotland or Wales stretches credulity. Two of the excuses hold water. This one does not.
A digital giant on analogue rails
This is the fundamental problem. Trainline is a digital company built on top of analogue infrastructure. It is a slick, 21st century technology business, a seller of mobile apps and QR codes, whose entire existence depends on a 19th century network of steel rails, Victorian brickwork and political compromise. The company has no control over the actual product it sells access to. It cannot run the trains. It cannot staff the stations. It cannot maintain the signals, yet its financial health is completely dependent on a system where all those parts must function in near perfect harmony, day after day. Trainline is a polished digital skin stretched taut over a fragile, complex and often warring physical body. When the body sickens, the skin suffers. The system is sick.
Trainline is a non combatant caught in the crossfire of a long and bitter industrial war. This is not a simple dispute. It is a messy, triangular conflict fought between the railway unions and the private train operating companies, with the government now acting as the ultimate paymaster for the whole industry. Each party has its own objectives. The unions are fighting for their members' pay and job security in an era of high inflation. The private operators are trying to deliver services under franchise agreements that were rendered almost meaningless by the pandemic. The government is trying to control a spiralling subsidy bill that ballooned to £12 billion last year. Trainline has no seat at any of these negotiating tables. It can only wait. It is a spectator to the arguments that determine whether its own customers have a train to catch.
A solution was once promised. Great British Railways was supposed to fix this. It was meant to be the single ‘guiding mind’ for the network, a powerful public body created to end the fragmentation and infighting that have defined the railway since privatisation. The vision, championed by the former transport secretary Grant Shapps, was for GBR to manage the infrastructure and contract private companies to run the actual trains to its own specification. This would have provided clarity. It would have provided a single point of accountability. The project has stalled. The legislation required to establish GBR has been repeatedly delayed, a victim of shifting political priorities in Westminster. It is a ghost at the feast of every industry conference, a symbol of strategic drift.
This uncertainty leaves Trainline in a perilous position. Its future in the UK is tied to the whims of ministers. Nobody knows what happens next. In one possible future, GBR is eventually created and decides to build its own state backed ticketing app, using its monopoly power to starve independent retailers of data and eventually rendering them obsolete. In another, a future government might decide that building a complex technology platform from scratch is far too difficult and expensive. It might instead choose to partner with the existing market leader, effectively anointing Trainline as the official digital arm of the new railway in a single, hugely lucrative contract. Oblivion or salvation. For investors, that is a difficult bet to make.
What are investors watching now?
Investors reacted badly. The announcement on 11 September, revealing completely flat sales in its primary UK market, prompted an immediate sell off that erased millions from the company’s valuation before the morning’s coffee had gone cold. The reason was simple. A technology company listed on the FTSE 250 is valued not on what it earns today but on its potential to earn much more tomorrow, and this trading update suggested that for Trainline’s British business, that tomorrow might never come. Growth had stopped. The story has changed. What was once seen as a high growth technology stock now looks uncomfortably like a low margin utility, one yoked to a deeply unreliable piece of national infrastructure. That is a much less attractive proposition. It demands a much lower price.
There is, however, another story. Buried beneath the grim UK figures is a more optimistic picture from the continent, where Trainline has been steadily building a presence in the newly liberalised and fragmented rail markets of countries like Spain and Italy. Europe offers hope. Unlike the monolithic, state influenced British system, these markets present a complex web of competing high speed operators, creating exactly the kind of customer confusion that a simple, all in one ticketing app is perfectly designed to solve. This is the new engine. International ticket sales provide a substantial and fast growing part of the group’s total business, a crucial counterweight to the stagnation and political interference that has paralysed its home market. But the anchor is heavy. The UK still accounts for the vast majority of the £2.1 billion in ticket sales reported for the half year, meaning that problems in Britain can easily drag down the performance of the entire group, no matter how well the European arm performs.
The board must act. The City will now be watching the chief executive, Jody Ford, very closely for any sign of a new plan, because blaming strikes and hot weather will not be accepted as a long term corporate strategy for a publicly listed company. Answers are required. When the full year results are published, analysts will comb through the documents looking for a clear response to the UK slowdown, whether that means a painful round of cost cutting to protect profits, a downward revision of future growth forecasts, or a new initiative to wring more revenue from British passengers. Something has to give. The fundamental promise Trainline made to investors at its flotation was one of digital disruption and explosive growth. It sold itself as a nimble technology platform, not a passive victim of Britain’s analogue railway politics. That narrative is now broken. The executive team has to build a new one. They must do it quickly.
