There is a single td tag with css-sched-table-title but a list with css-sched-waypoints.

Also, aligning to the correct syntax it should be Elements row = doc.select("td.css-sched-waypoints");, refer to here.

Note: html file is used as is is invalid and jsoup would not interpret it as valid table html contents. I had to enclose the content above within <table></table> tags.

When I try the below code with your html file:

Elements row = doc.select("td.css-sched-waypoints");
    Element title = doc.select("td.css-sched-table-title").first();

    System.out.println(title.text());
    Iterator<Element> iterator = row.listIterator();
    while (iterator.hasNext()) {
        Element element = iterator.next();
        String id = element.attr("id");
        String classes = element.attr("class");
        String value = element.text();
        System.out.println("Id : " + id + ", classes : " + classes
                + ", value : " + value);
    }

I get,

Saturday - Afternoon
Id : , classes : css-sched-waypoints, value : Townline and Southern
Id : , classes : css-sched-waypoints, value : Clearbrook and Blueridge
Id : , classes : css-sched-waypoints, value : Clearbrook and South Fraser
Id : , classes : css-sched-waypoints, value : Ar. Bourquin Exchange
Id : , classes : css-sched-waypoints, value : Lv. Bourquin Exchange
Id : , classes : css-sched-waypoints, value : Downtown Abbotsford
Id : , classes : css-sched-waypoints, value : McMillan and Old Yale
Id : , classes : css-sched-waypoints, value : Sandy Hill and Old Clayburn
