Proceed at slow speed, 15mph passing signal and through turnouts, next signal is displaying a Clear, proceed aspect.

Is the yellow-red flag a warning of a possible need to stop for men or equipment on the right of way? I am familiar with its use for that purpose in the US (GCOR rules).

Any corrections, please let me know!

Bang on, Tim!

The first signal is on the far right, Slow to Clear. The train crossed over from the south track to the north track, which is why the north track is showing a Clear-Proceed while the south track shows a Stop signal after the first green.

The yellow-red flags mark the boundaries of a block of track held by a track foreman. Before entering the block, the train must negotiate with the foreman for access through his/her block.

OK then, the yellow-reds are the same as in the US GCOR rules. Excellent blog, btw...enjoy it very much!

Hi Vaughn, the train is on the CN Rivers subdivision in Winnipeg, approaching the diamond crossing of the CP La Riviere subdivision at St. James Junction near the golf dome.
