This page uses accordion sections to conserve space in your browser window. To show or hide a section, click on one of the buttons above that section. When a section is collapsed it will give you more screen space to see the pie charts that will show up at the bottom of the page. Initially, you may have to click twice on a button to make it respond.
Some pie charts were updated in January 2020. The new charts are flat. The older charts made in August 2019 look more like an antacid tablet. For these the new data has not changed the proportions.
Select two trains symbols. You can either click on the checkbox or the symbol name to make a selection. After you make your second selection, the progaam will display two pie charts at the bottom of this page so you can compare consists. This can be helpful in determining the train symbol as several of the Q and Z trains look similar. As stated elsewhere, the size of the pie doesn't make a difference. Also the colors are not consistent with the types traffic. Press the Clear button to start over. Press the Back button on your browser to return to the previous page.
If your browser uses tabs, you can copy the URL for this page, open another tab and paste in the URL. Now you can select two trains in the first tab and two different trains in the second tab. You can then compare four pie charts by flipping back and forth between the two tabs.
