4-8-4 GS-4 Traction on grades

[jlester]

I have a couple of the older GS-4's. While they run fine on level ground, the are unable to go up a 2% grade. Anyone have any ideas to solve the traction problem?

• reduce the steepness of the grade.
• increase the wieght inside the locomotive, but this may lead to failure of the drive axles.
• if failure occurs, consider the Bowser repower kit.
• make the tender into a booster using model diesel locomotive components.

Or get that powered truck by (I think) Caboose Hobbies, and stick it in a passenger car behind the engine.
