Hi guys, I'm having trouble with a scenario on the Mount Shasta route. It is "SP Weed Local" from the Mount Shasta Scenario Pack by High Iron Simulations. After doing my switching at Mount Shasta, and it's time to pull out from the Mount Shasta Siding Center with my new pick-ups, I can't move. Throttle at 100% with no wheel slip, sand on, train and loco breaks full off, and I can't move. Amps at 1500, but nothing...I'm stuck. Has anyone else been able to complete this scenario? If so, what's the secret? Thanks!
Kodiac my friend, I've just passed that point successfully (using my standard ±5 cm slack action coupler). Again there is an issue with questionable coupler parameters. JL sets the slack to 0.0001 m. What the?! Too bad some devs don't read the forums. What this means is that the locos have to pull the full weight of the train from a standstill - they can't obviously. Using the slack, they only pull the weight of one car, then two, while gaining speed and finally when the train is fully stretched the whole weight is pulled. That's how it works in real life. I'll upload the Shasta coupler fix on the Technical Forums. Using my coupler, I managed to get the train moving on that grade.
Wow...good stuff, Torf! You the man! And I understand what you're explaining. I stood no chance of pulling the full train weight from a dead stop. And how cool that "slack" is something that is very important to train operations in real life! I just learned something! Thank you!
That's why I love US railroading - there is so much physics involved. Really looking forward to that southern barbecue Kodiac
Oh man, I remember those Amfleets with these horribly huge slack in them! I am not sure which route, as it has been many years ago when I noticed these. But are they still not fixed after so many years?
Because nobody tells me which ones they are exactly Peter posts the screenshot and lets us do the guesswork...
At first guess this is a historical shot, looks like on one of Canadian routes or maybe around that time. CMP has these trees, and Donner. New York - New Haven was, I recall, bogus like that, but it was fixed. Possibly the other versions, too (NEC NY-Ph, Miami-WPB). The shot name, if that rings any bells. I can't deduce the year from it. screenshot_canadian-mountain-electrics_51-42438-116-18027_12-16-52-jpg.11143
If what torfmeister said doesn't help, here's a pointer to something else that's possible: wheelslip. I ran a scenario recently with the SP SD70M, some moderately heavy coal (60-80 wagons, 4 locos of around 15k bhp). During my first attempt I simply coupled one loco. The rest was slipping entirely, even under minimum breaks (I was starting on the grade at Colfax). For some reason I didn't slip down, and applying any amount of power did accelerate my train, however just a wee bit, regardless of notch 1 or 8. I guess it was a rounding thing, but I didn't fully understand as I did slide down during my green ear days having assembled a megalomaniac train in the autumn free roam. Possibly an edge case as my lead loco actually had grip. My ultimate solution was to have a very realistic start: I've split the consist into 6 segments: loco, cars, loco, cars, loco, and my own starting in a siding. 15 psi was just about insufficient so I started with casually sliding down and auto-coupling. Similarly, there is one consist in a CMP free roam which can easily climb anything in notch one, but it slips above anything but 20 Amps (even after decoupling, no surprise there). Decouple, save, reload, win. Long story short, don't save with engines in a long consist, they have no grip. The train should be able to start actually, even stretched, considering you have massive extra starting effort and when stopping uphill, you likely stretch anyway (you can bail and even power backwards under brakes if you want to compress the front). I can't imagine anyone hiring 10+ people to apply and then release handbrakes at the rear of the consist each time
Believe me I had no trouble. Use the sander, notch up, then release the brakes. The added slack will help you pick up speed until the last car starts moving.
I was just posting an old shot in relation to stretching couplings. I don't know if it was fixed but I think it is the stock that came with New York - New Haven. It might have been fixed but I don't have the route currently installed on my computer - too much other European stuff It is the Canadian Mountain Passes Route - I cloned it and added Electrification properties to the track Never go round to putting up OHLE before I gave up on it
Maybe it is from the old Northeast Corridor - that DLC was removed for a while and then an updated version was released iirc. Have not come across these funny couplings yet
