</span></font></div><div><font face="Arial"><span style="font-size:15.454545021057129px;white-space:pre-wrap">The problem is, that there are multiple "attributes" and therion does support only hide show for single symbol type. Therefore, specification is tricky. But in your case, this is what you can use:</span></font></div>

You can use also symbol-show point station to show all kinds of stations.</span></font></div>
