Fare Calculator 2013

New version available for fares change December 1st 2012

While still a work in progress it should now accurately determine the fare for intercity journeys nationwide. A few stations are not available currently mainly some WRC and KRP stations due need to confirm distances and locations

It does obey most of Irish Rail's strange rules, so Athlone Mullingar is still quoted via Moate (but includes Luas transfer), Cork and Kerry to Limerick always go via Croom

It can not handle Rosslare to Cork due to Irish Rail seemingly having built a secret railway from Dungarvan to Youghal, so until we have some numbers on this mystery its going to charge the logical fare by true rail distance

Does this Athlone - Mullingar trick mean that you could get away with buying this and travelling from Athlone to Dublin this way for a considerable discount?

Sure does, still need to check what the station level machines do, but online this is what Irish Rail quote and it maps to the correct fare for the distance. Note we have a bit of problem, booking office fare Limerick Ballybrophy goes via Limerick Junction, but the TVM goes via Nenagh (logically the shorter route) and charges less.

Its a legit fare and since you change at Connolly and Heuston (Luas is actually included on the ticket!) its hard to catch you as break of journey is allowed*

We are working on adding switches so you can
1) Run the fare calc in Irish Rail quirks mode (default)
2) Logical shortest possible rail route
3) Enable/disable the future distance zone rules (this new zone is indicated in results currently)

When we get the data we will add the Northern Irish network in as a well for journeys originating in the Republic

We in theory now can generate the any to any fares matrix thanks to a bit of graph theory we can do in a fraction of second what currently takes Irish Rail weeks to do manually if they had to redo the system "single-source shortest path problem for a graph with nonnegative edge path costs, producing a shortest path tree." http://en.wikipedia.org/wiki/Dijkstra%27s_algorithm

* Note RUI never condones fare evasion or breach of T&C's however this is more like tax avoidance as distinct from tax evasion, grey

What is the story with using a Cork/Rosslare ticket to travel to Heuston?

Mark Gleeson · 02-12-2012, 16:02

Same thing however on a cost basis it doesn't really offer a saving which justifies its use

If travelling from Dundalk to Clonsilla it seems to be cheaper to buy 2 separate tickets: (1) from Dundalk to Balbriggan and (2) from Balbriggan to Clonsilla. I presume this is allowed if you take a commuter service from Dundalk (which stops in Balbriggan), but is it allowed if you take an Enterprise service from Dundalk (which does not stop in Balbriggan)?
