Under the rail franchise agreement during the bid process, the terms might mandate that journeys from A to B cost £10, and that journeys from B to C cost £5. There might be no obligation to price travel from A to D via B & C at a particular cost, so a rail operator might make that more expensive.
It’s silly from the consumer perspective, but it makes sense for the rail operators to do this in order to maximise profits.
