Honestly, if they aren't DCC equpited and "speed ranged", I doubt that they'll run well with Kato or Atlas or Walthers/Life-Like engines...nobody else does. Everybody has their own motor speeds and gear reduction ratios. You might be able to arrange the various engines in a consist so they'll push and pull each other acceptably...I've done it with Atlas and Kato engines, but it isn't ideal.
