Raileasy, a big online rail ticket specialist, operates an affiliated website dedicated to cutting costs by splitting a long trip into separate low-fare segments. Currently, the website claims some impressive “savings” up to 66 percent. However, when I checked a few trips, the supposed “savings” were mainly due to use of advance-purchase tickets. I couldn’t find any big reductions due solely to split tickets. Maybe I didn’t try enough tests.
If you’re traveling by train in Britain, you might give a look at raileasy.trainsplit.com/main.aspx?
