If you’ve been playing Stardew Valley for a while, you must have noticed that message which informs you about a train that is passing through Stardew Valley. And you probably want to see what’s up with the train, so you go to the town’s train station, only to discover that the train is already gone.
At least that’s what happened to me way too many times until I finally managed to come on time. So what happens? Basically you get to see the train. Why is Stardew Valley train useful? Some resources tend to fall out of the train as it goes by, you can pick them all up. This might be useful at the early stages of the game when you are struggling with pretty much everything but later on there is not much point in going to see the train besides to get a look at it.
Here’s a video that shows what happens when a train passes through Stardew Valley, you can check it out if you were not lucky to see Stardew Valley train yourself.
