London to Dublin - two Sail Rail hacks!

SailRail tickets combine your rail journey to a port, and your foot passenger journey on a ferry.  Despite the rise in cheap flights across the Irish Sea, they are still popular on the Holyhead to Dublin route - especially at peak times or last minute, when air fares are extortionate!

The advantage of SailRail tickets are they are fixed price.  So for example London to Dublin costs either £53.40 for an "Advance" ticket, or once they sell out it's £60.10 for the misnamed "Standby" fare.  Tickets from elsewhere in both GB and Ireland are on a sliding scale, as per this old map - all ferries now serve Dublin port!

Most days there's a 9am train from London Euston which gives you 80 minutes to see the sights of Holyhead, before the huge Irish Ferries ship Ulysses pulls out of port and delivers you into Dublin around 5.30pm - where you stroll across the gangway back onto dry land.


If the journey that you want is showing as Sold Out / Unavailable - try booking Bangor (Gwynedd) to Dublin departing at 12:23 - the last stop before Holyhead.  If this shows as available, you know that it's the train that's causing the problem rather than the ferry that's sold out.

Since the pandemic, Avanti require seat reservations for SailRail tickets - even though they always have a couple of carriages that don't have any seat reservations!

When I've encountered this problem I've tried multiple rail reservation websites, and none could overcome the Avanti block.

Avanti Hack

However, if you go to a mainline station with a ticket office, they should be able to sell you a ticket for the date you want, without a specific train.  Since most stations only sell a handful of SailRail tickets it may take some time for them to work it out. And make sure they select correctly between Irish Ferries (Dublin Ferryport - DFP) or Stena (Dublin Port Stena - DPS).

Then it's just a case of getting past the Avanti staff at the gateline and onto the train with your open ticket!

Sunday Hack

The 9am direct train to Holyhead unfortunately doesn't operate on a Sunday (or if Avanti amend the timetable) - so you'll need to find a connecting route.  If you want to get the 2.10pm Irish Ferries ship, rail reservation websites say you need to depart London Euston just after 8am.

However if you select Dublin Port Stena (for the later ferry) you can book connecting trains which should get you into Holyhead a tantalising half hour before the 2.10pm Irish Ferries departure.


With the last transfer bus to the ferry departing the terminal 20 minutes before the ferry leaves, if the trains are on time you can make the 2.10pm ferry - even though you can't actually book it.

Once you arrive at Holyhead station you need to go to the rail ticket desk (not the Irish Ferries or Stena ticket desk) and ask them to swap your ticket from Stena to Irish Ferries.  As you enter the station/terminal from the platforms, the rail ticket window is on your right facing the ferry ticket desks.


When I did this recently the rail ticket staff member was rather confused and actually issued me a new ticket the same as the old ticket. But thankfully the Irish Ferries checkin staff let it go, and issued me a Ulysses boarding pass anyway.  I guess they appreciated my effort!

So if you value an extra 40 minutes in bed and are willing to take the risk that you may end up on the Stena ferry if your train is late into Holyhead - then give this Sunday Hack a bash!
