Increasingly savvy rail passengers have discovered that ticket
splitting can significantly reduce the cost of rail tickets, with
websites and mobile apps being created to meet the growing demand.
The basis of ticket splitting is that instead of buying one ticket
for the whole journey, buying tickets for component parts
separately can be cheaper. The passenger can travel on exactly the
same train as they would have done buying one ticket for the whole
journey, and there is no requirement that they leave the train and
get back on it between the start and end of the journey.
The train travelled on must call at the stations the tickets
were bought for, not just pass through the stations. For example,
if a passenger wishing to travel from Edinburgh to London buys one
ticket from Edinburgh to York and one ticket from York to London,
the train travelled on must stop at York.
