Hi Folks, I thought I'd try a run with full snow, full cloud and nearly full wind settings. so I chose the 07:56 Laramie to Cheyanne manifest with the UPSD70ace. Can anyone test this item. I can't get closer than about 3.8 miles from the first "Go Via" without the train stalling and sliding back a mile on the 1.6% (going forwards) 0.8% (Sliding backwards) slope. I had it in N8 with sand. Any tips on how to complete would be appreciated Cheers John
Banking doesn’t help, I’ve ran with it on. In snow these 11000 and 13000t trains stall out near a bridge on a 1.5% grade. I’ve dabbled with loco brake and throttle and this train only rolls back down the hill in snow. I’ve tried this 2-3 times and I’ve got out the yard fast too. Personally I don't think there’s enough power, even sanding these spin on notch 1,2 and 3
I don't know about this exactl train in this exact conditions, but with the heavy trains in low-traction conditions you will often have to be very careful. Meaning sanding is not enough, you will have to user lower throttle and even fine-tune it with the loco brake. So to get started, it's like throttle in notch 2 or 3, and slowly control it with the loco-brake, because notch 2 is not enough to get started, but notch 3 by itself will wheelspin, so a bit of loco brake is needed to fine-tune the power. And heavy trains will will sleep in notch 8 even at speed, so you will have to go notch 6 at max.
There’s a few this don’t work with unfortunately , Going up the grade your speed start to decline and then there’s a small step up to 1.8% before going back to 1.5%. I have used the first three notches , about 35-40% loco brake stops the slip but you need to release it further to get to 0.2mph. You can drop to 30-35% loco and it spins. I’ve spent 30mins trying to get this going here after it ran out of speed. I don’t have issues with any other hill starts On any route
Thanks for the replies folks. I'll have another play and see if the N2-3 and direct brakes help. If it does, it will be a Looong scenario...
If you have the option to try it in another weather setting, that might just simply rule it out to adhesion rather than total horsepower
Tried it again. Same train, February, default settings for the timetable (i.e. no changes to weather, etc.) Rolled through the area with a minimum speed of 14MPH. There's some framerate killers in the area as well, and a bit of an elephant race as you head toward the objective marker.
There are some heavy freight services - or at least there are in Sand Patch and Clinchfield - which simply can't be done in the snow. In real life, the RR would assign additional traction.
I was tyring this very service last night with the same results. First attempt the month was February, all weather sliders to the left except snow which was fully to the right. Train stalled on the 1.6% several miles from the Go Via icon. Next I tried the same settings but with only a tiny bit of snow slider, just enough to add a bit of snow on the ground. Same results. Last I tried with the same settings but with the snow slider fully off to the left and got the same results as the OP, made it up fine albeit at 14mph through this section. I wish the game would automatically add locos to compensate for this, or allow us to contact the dispatcher and summon a couple helper units. Or at least grey out or flag these services if they can't be completed in the chosen weather settings. Its frustrating to spend 30 or 40 minutes on a service to find it cannot be completed. DW
