People in Ireland are heading to the polls today to vote in a referendum on legalising same-sex marriage.
People making the trip back to Ireland are sharing their journeys using the hashtag #hometovote.
This is the scene on the 9:10 London to Holyhead train as Irish abroad return #hometovote #marref
And they're coming in force.
Jesus. The queues in Dublin Airport to back home for the #MarRef are crazy. Halfway down Pier D by the looks of it.
Voters are travelling back from places such as Ethiopia.
On my way #hometovote from Ethiopia! Wrecked tired, almost crying reading my Twitter feed, itching to vote! #MarRef

Even Hozier is heading home to vote too.
Éire! Have some hrs free, flying in to vote tomorrow. It's the most important thing you'll do. Don't forget! #MarRef
Some people are returning to find nothing has changed.
Came #hometovote, my Dad told me to shave my beard and my Mam needs 2 months of tech advice. This better be a Yes.
But others are finding some welcome surprises.
Came #hometovote all the way from London and found my mum had made some subtle changes to my room for me #VoteYes
Opinion polls suggests that the referendum should result in a victory for the Yes campaign, but we'll find out on Saturday.
