I have three NScale engines - two KATO and one Atlas. No DCC. The two KATOs run at roughly the same speed. The Atlas is much faster. I have 36 box cars. If I run the KATO and Atlas by themselves (just the engines - no box cars) they of course run faster than they do pulling the 36 box cars.
My question is: Is it OK to run the Atlas and KATO engines together with the Atlas in front, when all 36 box cars are attached? I know I should not run them together at the optimal speed for each, but I figure if none of them can run at optimal speed with all 36 cars attached it should be fine running the Atlas up front. This is why: the KATOs are not pulled faster than their optimal speed and the Atlas runs closer to its optimal speed as it has less friction pulling the 36 cars with the KATOs helping. I plan to go to 50 cars.
Is it OK to run them this way? I'm new to all this, but am having a blast.
