Vernon mentioning the train

[KMatt]

I think it must be the herd approaching. It was already implied in the last scene in the morgue. They used the same sound effects as they did in the herd scene in ep3.

Since we have been in Savannah the largest group of walkers we have had to fight have been about a dozen or two dozen (12-24); the herd is comprised of THOUSANDS of walkers, all moving together, all going in the same direction. You don't fight herds, you run (or hide). Thats why Vernon asked Lee to hand over Clem; he saw what was coming, and thats why he and his group have done a runner.

Savannah is overrun.

If he saw thousands of walkers, why would he then ask about the train? It seems like a bad time to play the blame game. Even so. Why not warn them before leaving? He dosn't stand to gain anything for whitholding that information. I believe, that he and his people have taken the train.

He would ask about the train because he wanted to know if his group could somehow leave the town before the herd overruns savannah...
I think he wanted to stick with his own group and didn't fully trust lee's group, especially since they lost brie. So he decided to leave with his group alone and allow lee's group to go their own way. The train basically is the perfect getaway vehicle for them.

If you don't lie about Clem being your daughter does that affect his dialogue? Maybe because you left out / mis-told information he doesn't feel the need to tell you whats coming or as revenge for Brie.

He probably took the train and thought nothing of it since your group is getting ready to get on a boat. I'm sure if you didn't have the boat option he wouldn't be that morally wrong as to just let you get trapped? (though this is giving him the benefit of the doubt)

My first thought when he mentioned this was that he was probably thinking of getting in the train and getting the hell out of Savannah, and I think I'm sticking to that. He knows for a fact after asking that they came on that very train, and also that they were going to leave by boat, meaning they would have no use for the train any longer since they obviously weren't planning on going back to it, leading to him saying 'never mind' since it probably didn't matter if he wanted to use the train or not, seeing as they no longer wanted it.

And I do think there was a bit of a railroad/train-ish sound when they saw the walkers through that narrow slit in the morgue. My guess is that they left in the train at that exact moment and the walkers were chasing them. But who knows, all we can do is guess. In fact, it might not even be of significance to the next episode if you think about it. I think it only served to imply the reasons as to why the morgue was empty, nothing more.

Edit: I didn't see the previous post when I wrote this, which kind of pointed out the same thing as I did! Well, guess that makes two of us.
