Pick-ups Again.

 This 94XX looks a little distorted but is a trick of the camera!
The lower pic shows the chassi- similar to the first in the series but with the sheathing from layout wire threaded on to the pick-ups to prevent shorting on the uncoupling wires.
Not all my locos do this but those that are prone have had this mod made to them.
All you need to do is strip the outer from thin wire and thread it onto the pick-up and the insulation is complete. A spot of Superglue is sometimes needed to keep the sheathing in place.
