Bug/Issue Game crashes when going for train

Hello,

The title pretty much says it all... I tried in the first year to go the the railroad after having the "a train passes through Stardew Valley" message. I went up, and when the map loaded the railroad, the game crashed immediatly. For a while I stayed away from it altogether but it works fine as long as there isn't a train.
Just now I was nearby when I got the message and not much had happened in my day, so I went for it and it crashed the exact same way as the first time. There's no issue to re-launch the game after that and it runs smoothly otherwise.

I have the Steam version up to date. I use Windows 7 Pro edition. My graphic card is also up to date.

Thanks ^^
