Kingston Woods is a nice area that has held it value well.
The number of trains passing through there is not high. However, unless a buyer really likes trains, or is willing to pay less to live near a track, then the number of people who would be willing to purchase and live there is going to be somewhat limited.
There are exceptions to everything. For example, train tracks don't seem to bother those who live along Westland to the south and in Echo Valley.
