For many it is still a rite of passage amongst young European travellers - the month-long jaunt around the continent using an InterRail pass for unlimited train travel.
The concept is simple: pack as many cities into a four-week period, by using a combination of trains across Europe's vast and (mostly) efficient rail network.
The pass is still seen as one of the best value-for-money and enjoyable ways of exploring Europe in a reasonably short time frame, not least because of the community aspect of like-minded travellers hopping on and off trains together and meeting in numerous hostels around the continent.
Whilst the romanticists of the InterRailing genre point to movies such as Richard Linklater's Before Sunrise as the epitome of the self-discovery movement that it gave birth to, others will often point to other, more earthly reminders of what the InterRail trip meant.
In particular, Thomas Cook's European Rail Timetable - the bible of the intrepid European backpacker who needed to figure out where and when he or she was going to catch their next train.
Travellers would often be seen poring over the pages of their dog-eared timetable as tried to fathom out the minutiae of the European rail system and schedules at train stations or hostels.
Of course, InterRailing has changed massively over the past decade with the introduction of low cost flights around Europe and high-speed rail networks charging a premium on top of the up-front fee for the pass.
But the need to plan a complicated, sometimes 20 to 25-stop tour of Europe hasn't altered... the method.
InterRail's parent company, Eurail, has had an app in the marketplace for some time that allows users to see the timetables and get maps of destinations, but true online trip planning has been harder to come by.
Step forward InterRail Planner (obviously) and its claim to be a "revolutionary" product that puts all the tools required into the hands of users on the web.
The site allows users to interactively build a route, getting information on journey times and links to make reservations (many operators insist on InterRail pass holders having secured a seat), as well as tips and links to accommodation.
The Rome2Rio API provides the transportation information, whilst HostelWorld hosts the where-to-stay elements.
The service is underpinned by a calendar function that stays with the user throughout the trip, so they can keep track of where they need to be on certain dates - an important function as some operators have restrictions on certain days that passes can be used.
Co-founder Jack MacHugh says the site will eventually be made into a mobile application and also integrate listings for events in various cities around Europe.
Goodbye, Thomas Cook's dead tree timetable, maybe...
