I have the Big Boy installed, and I tried it on the Marias Pass.
well…
I had a 50 car train and started it somewhere midroute, and everything was OK, till I started hitting the grades. I would run up a grade, hit the sanders and, errrngh, I stop.
You would think a Big Boy and 50 cars could make it over these grades. Nooo Way.
So I back down, and decide to double the grade. Cool. I find a passing siding and run back and get the rest of my cars.
I couple up and move on, till the next grade. Errns, no good.
So I try to double up again, half the train… errrrngh…no good…
so I cut off half the cars again and try the grade again…
Erngh, no good again.
soo now I back down, and now I make like 4 cars and try this grade again,…
Yaaaay!!!
I find another siding. I go to the previous cut of cars, and, the one siding I was trying to work wasnt on a level grade, and I couldnt hold cars on it, they kept rolling off…grrr, I had to use a short section of double main to single as a switching point.
So I go to drag my next set of cars up to my first set.
(note, this session ran thru a couple of evenings of playing)
Now I go back to my last section of cars and arrive, then suddenly…
“Session ended, ran out of fuel”
No coal.
Well, the Marias Pass is set up as a modern diesel line, theirs no coaling stations…
I dunno if MSTS has working coaling stations.
I’m going to have to set up a double header somehow on this route… sheeshe, I can;'t make it with a big boy and 50 cars with all this doubling…
