Summary
[edit]DescriptionTTC interlocking signal.JPG |
English: An interlocking signal on the Toronto Transit Commission's subway system.
The yellow-over-green aspect indicates that the train may proceed with caution; the next signal on the line is currently at stop (red). The lunar white lamp at the bottom indicates that grade timing is in effect for the next block, and that the next signal is red only because of grade timing. |
