Trainline: the middleman the government keeps trying to replace
____________________
THE SETUP
Trainline shares fell 34% in a single session in May 2021. The government had just announced it would build a ticketing platform to replace it.
Founded in 1997 by Virgin, National Express and Stagecoach to sell tickets across Britain's newly fragmented rail network
Sold to Exponent Private Equity for £163m in 2006, to KKR for roughly £500m in 2015, then floated at close to £2bn in 2019
FY2026: £6.3bn in ticket sales, £453m revenue, £177m adjusted EBITDA
The government has proposed replacing Trainline three times since 2021. None of the three has launched
Two private equity owners in a row made Trainline bigger before they sold it. One made it digital. The other made it European. Now Trainline is selling its own booking technology to the operators supposedly in competition.
Trainline succeeded because of two things. Its owners spent thirteen years turning a small UK reseller into a European platform. Then Trainline started selling its own technology to train operators. That second move means even a government replacement might have to buy from Trainline to exist.

THE PLAYBOOK
1. Selling order to an industry that can't sell itself
British Rail's 1990s privatisation split one national network into dozens of competing operators, each selling tickets through its own channel. A passenger comparing routes from London to Manchester might need four different websites. Virgin built Trainline in 1997 to be the one place that did the comparing
It worked well enough that the rail industry's own trade body pushed Virgin to sell it, arguing passengers were better served by a retailer no single operator controlled. That pressure led to the 2006 sale. By FY2026, Trainline was handling £6.3bn in ticket sales, with digital sales making up 62% to 70% of the UK's online ticket market
It’s a clever play. Trainline solved a coordination problem its suppliers couldn't solve for themselves, because solving it themselves would have meant one operator favouring its own trains over its rivals'. Replacing Trainline doesn't just mean building an app. It means getting every competing operator to agree to hand a shared customer relationship back to a single body, which is the exact problem Trainline exists to avoid.
____________________
Takeaway: When an industry's own structure confuses its customers, whoever removes the confusion gets paid by the operators as much as the passengers and becomes hard to dislodge once both sides depend on it.

2. Two owners, one asset, from £163m to £2bn
Exponent bought Trainline for £163m in 2006, when it was a phone-and-early-website ticket reseller processing £400m of ticket sales a year and earning £11.7m EBITDA. Over nine years it hired an eBay executive as chief executive and turned the business into a genuine digital platform
EBITDA reached £21m by 2015, the year KKR bought it for roughly three times what Exponent paid. Within a year KKR bought French rival Captain Train and rebranded it Trainline EU, spreading the platform across France, Germany and Italy. By the 2019 float, Trainline was selling £3.2bn of tickets a year on £210m revenue, valued at close to £2bn
Each owner added a capability the business didn't have before selling it on. The valuation followed the market each of them opened, not a round of cost cutting
____________________
Takeaway: A private equity flip that only cuts costs sells the same business back to the market. One that adds a real capability sells a bigger opportunity.

3. Building the technology
Trainline reports three divisions. Trainline Solutions licenses its booking technology to train operators' own websites and to corporate travel managers, rather than selling tickets to passengers directly
Solutions generated £1.1bn of the group's £6.3bn in net ticket sales in FY2026, up 15%, faster than either consumer business
If Great British Railways ever builds a unified retail platform, licensing infrastructure that already works is the faster route than building one from nothing. Trainline is betting its own technology ends up inside whatever app replaces the front end, regardless of who owns the brand
____________________
Takeaway: If the thing that might replace you needs infrastructure to exist, build that infrastructure first and be the one selling it to them.

ONE MORE THING
The government has proposed replacing Trainline three times since 2021: the original Great British Railways plan, a January 2025 pledge to build a new retailer once GBR exists and a March 2025 promise of one app for every operator. Each time, the plan was delayed, cut back or dropped before it launched. By mid-2026, Great British Railways still didn't legally exist.
Trainline's revenue grew slower than its ticket sales in FY2026 because it cut its UK commission rate. Maybe that was to head off regulation. Maybe it was just competition. Either way, it took away the simplest reason to legislate against the fee.
A regulator criticised Trainline's booking fee disclosure back in 2023. The law built to punish that kind of practice only issued its first fine in April 2026, against a driving school. The tool exists now. It hasn’t been used on Trainline yet.
Trainline succeeds because each stage made it harder to remove than the last. Fragmentation created a job none of the operators wanted to do. Two owners in a row got paid for making that job bigger, not cheaper, turning a £163m reseller into a £2bn platform. Now government wants the job back, but the job has grown roots. Trainline doesn't just sell tickets anymore. It supplies the technology other companies use to sell them too. Whatever app passengers open next, there's a good chance Trainline built part of it.
