Right now this is the most accessible method to me. But my going out would still rise suspicion in this house. If I'd do it, I'd try at night, at a point of the railway with as little light as possible (plenty of these here), and I'd try lying down as close as possible to the train (though I am pretty sure my SI would kick in strong). I'd also try wearing dark clothes, to further hide myself. Around two weeks ago a man died like this, nobody knows whether suicide or accident (he was lying on the railway, but he's a know alcoholic, so he might have passed out); the news say the conductor saw him from 50 meters and tried to stop the train, but was unable to, hence my wishes to lie down as late as possible. Also, I can't find a way to track the passing of trains in this town, they seem to come at random intervals.
