Is this a Split Chassis Loco?

That the casing of the motor is in contact with the chassis doesn't always mean that its a split chassis. The case will be a support for the motor magnets, the brushes will be mounted on the insulated plastic ends.   It's more informative to know where the motor brushes are connected.

 

  1. Are they wired to opposite sides of the chassis (=split)
  2. Is one motor brush wired to the chassis and the other to insulated wipers against the wheels on one side (=not split)
  3. Are both motor brushes wired to insulated wipers against the wheels on one side (=not split)

 

Of the above cases,  1 is a split chassis arrangement (you should be able to see an insulating arrangement between the two halves of the chassis), 2 is the traditional live chassis used in the past, eg Triang locomotives and 3 is the method used on most modern models.

 

Hope thats helpful!
