London Gatwick Airport Forum | Plane to train connection

I'm a US citizen visiting the UK/Ireland area for about a month. Part of my journey has me flying back to London Gatwick from Cork, Ireland by way of Aer Lingus. I will arrive at the south terminal at 2:15 and need to catch a train out on First Great Western (which is also in the south terminal) at 3:25. I will have 1 checked bag and will have to collect it after my flight.

Is this hour window long enough to go through any customs there may be, collect my bag and catch that train? The only other one going my way is 3hours later and I'll already have quite a ways a head of me so if it's possible I'd really love to know if this would work!

Thanks!

If your flight is on time yes, but only just, baggage reclaim can be a little slow but my last 2 visists were much smoother than before, they are, I hope, improving this aspect of the arrival. Passport control can also slow you down, although now they have machines to do it if you have an electronic passport. Saturdays can be pure h..l !
