We currently live about 30-50m from a track. 2nd row, but diagonal to the railway, so you can see a piece of track from the balcony. A freight train runs there a few times a day, a supply route for an "industrial operation". Yes, you can hear it. A dull rumble. Nothing vibrates, no rattling in the cupboard. But we got used to it so quickly that it doesn’t bother us. I find it much more unpleasant when car doors slam somewhere at night or someone talks loudly.
Still, we probably wouldn't build on the property you described. I also recommend spending longer periods there at different times to be able to judge the noise level, etc.
