An eastbound oil train has left CTC limits behind at Mesa and is now headed east in TWC (track warrant control) limits. So why is there a trackside signal? And an ever better question...why is the signal yellow when the train is in the block beyond the signal? The key is the "D" plate located on the signal mast near the bottom. That "D" plate indicates this is a "distant signal". This signal does not give any occupancy information about the block ahead. It only gives westbound trains an indication of the CTC signal at the east end of Mesa. Since that signal at East Mesa is currently red, this distant signal shows a yellow (Approach) indication. If the signal at East Mesa were green, this signal would also show a green. Even with something in the block immediately beyond the signal. Indeed, in TWC limits, there are no "blocks" per se.

A westbound BNSF coal load sits idling on the siding at Barr. The train is currently tied down here, waiting on a fresh crew to come out of Denver. There are only two tracks (Coal 1 and Coal 2) at the yard in Denver that BNSF can use for trains waiting for a recrew. When both of those are plugged, they have to find alternative places for tying trains down.

Forest fire in the the Oregon and Montana area have resulted in a week of very hazy skies in Colorado as prevailing winds have taken the smoke southeast. While not particularly enjoyable as the air quality has significantly decreased, the one benefit about the smoky atmosphere is a bit of red and yellow near dusk as the sun shines through the smoke. Meanwhile, a westbound UP oil empty rolls west on the single track main of the Limon Sub toward Denver.
