Derailment or NMRA standards scale model weight. The most H0 scale freight cars I have, have a recommended NMRA weight between the 100-170 grams. That’s because you don’t want a derailment. Specially not in the tunnels. So, I have a list, where you can calculate length of each freight car to recommended NMRA weight. You can find that list on my website “www.ronaldshobby.com”. I did a test to put that extra weight out. Better for your locomotives. But you see, I had a derailment. With a curve radius of 90cm/35”, climbing 2.1% is maximum you want to go. Better below the 2%. But I didn’t had that extra length for less steeper slope. Because I had to climb to 11.2cm/4.4”. So, I creat all my freight cars for that extra NMRA weight. But also all metal wheels. Kadee couplers. For more quality running freight cars.

And you find the story on my webside ”Livingroom Railroad 2022” after you click on “H0 scale”. Enjoy of all my drawings and work I made.
