    Default Slow down in curves

    I have two or three Atlas locos that slow down quite sharply in the curves at each sides of my layout. Has anyone ever had this problem? I donít understand where it comes from, but how to solve it ?
    All other locos are running normally.
    Thanks for your help.

    I don’t think so. It is Gp40 and all of my BLI ES44, ac6000 or intermountain sd40 runs normally on this curves.
    As all my French locomotives. Curves are R2 from Kato.

    You've probably already thought of this but make sure the trucks are free to swivel and the wheels are in gauge. I installed one of the trucks backward on one of my Atlas's (don't remember which) and the truck's power tab would snag up on the contact strip.

    Are you running DC or DCC?

    I'd check the wheel gauge. Sounds as if one or more of the wheelsets could have a tight gauge. Do you have an NMRA Standards gauge? Best value in model railroading.

    This ^^^^^^

    And while you have the gauge out , check the track gauge with it too , if nothing shows up in the wheels

    Double check to make sure the trucks don't interfere with the plastic shell ladders or anything like that.

    @Elwood

    I'd start with a thorough de-grease and re-lube.


    Good luck
