Jacqueline Reid, Duty Manager at Heuston Station in Dublin.
I LOOK AFTER customer services, everything from running the left-luggage locker room to organising the golf buggy to helping visually-impaired passengers get on their train.
We have a communications room, too, where we keep an eye on the 50 or so cameras around the station, making sure everything is okay.
We run a three-shift cycle, with the earliest starting at 6.30am and finishing at 2pm. It's my favourite because it means I can get out and play golf.
First thing I do each morning is check all the trains and platforms are listed correctly, and then I open up the toilets.
Then I sort passenger manifests for the hosts of the Dublin-to-Cork trains, so that they know who is sitting where in first class. I also make a run to Eason to get the papers ready for those trains.
After that, I can start dealing with messages left for me by the previous shift, and check the rosters to make sure no one is off sick. Once all that's sorted I can get out and about on the platform, which is where I stay most of the day.
By far the most frequently asked question I hear is "What platform does such and such a train leave from?" followed by "How do I get to the zoo?" Then it's what bus takes me to various hospitals, colleges, the city centre or airport.
It's a bit like an airport here, only people aren't quite so stressed. That said, if they miss a train because it went on time and they were late, somehow they seem to think that's our fault.
Mostly people are fairly jolly, buying their magazines and getting their bits and pieces. The atmosphere is good.
The most common problem is men and women going into the wrong toilet by accident. It happens all the time. Other than that, it's kids getting separated from their parents and having to be reunited.
Kids love trains. If it's quiet on a Sunday sometimes I'll bring them up to the engine driver to have a look around.
We get a lot of people losing their money or missing their stop, and arriving all upset. When that happens we have a little room we bring them to so they can have a cup of tea and sort themselves.
Where trains are busy I walk through and ask passengers to move bags or coats to make space for others. Passengers hate asking for themselves.
The biggest problems arise where a train is full and I can't let any more on. It can be very hard, but you've got to stay calm, even if there are 20 people shouting at you.
It's often because people buy tickets and think they are valid on any train, but online tickets are train specific.
If a train is very late I organise to have taxis waiting to get people to airports, or hospital appointments.
If there's a big GAA match on, or a rugby weekend, people can get boisterous. If they're too drunk we won't let them on, so we have to try and gauge passengers and see how they are.
I've often asked someone to go have a coffee and wait until the next train. It usually does the trick.
No two days are the same here, but all are equally busy, so I grab something to eat when I can, mostly a sandwich.
I have worked for Iarnrod Éireann for 21 years, but I was in an office before I got this job, a year ago. It's the job I always wanted. I love it.
