While running this timetable I noticed once you set out the hoppers that require setting out, you can not move forward because the CRR Extra that is going northbound is stopped at the signal right down from the Caney signal. Even after you back up to your caboose and couple up, you are still stuck in the siding waiting for the extra northbound to proceed and it just sits there. This has happened to me quite a few times. I even tried going over the speed limit to get there way ahead of this extra but still can not proceed south past this point.
This service requires that you move fast and don't dither. It can be done before that train shows up, but you can't muck around. I STRONGLY recommend you use the flying cameras for uncoupling and switches.
I just tried that and now I'm getting about there being a train in the block when I go to reverse up to the caboose to couple on to.
It finally worked this time. I just completed this timetable which I am very happy with. Now if they can get the Extra 3014 fixed it would be awesome. Then I will have the entire Clinchfield Route completed.
