As far as I am aware the only chassis that go "backwards" when the right hand side is positive were some of the old Egger ones. (Others may comment on this).

Also some old Lima 4 wheel and (I think) Jouef chassis

It would perhaps make sense that when operating the layout from the normal operating side that trains move in the direction the controller knob is turned (if it is centre-off type) or the direction the direction switch is set if it is of that type.

That's what I was after! :)

Mick is correct.

The egger locos with the Marx microperm/nanoperm 9 volt motor do all run in the opposite direction.
These are near imposiable to change.

The Egger tram loco with the Lima motor also run in the opposite direction but these can be changed by carfully re-solderind the wires to the other side of the motor. (Trying this on the nonoperm/microperm motor the heat on the brush contacts will destroy the motor!)
These all date from 1963 to about 1965.

The Jouef Decauville loco did the same in the first two years of prodution, but these are easy to change by turning the magnet on the motor the other way around. Again this was in the 1960's and by 1968 the Jouef Decauville locos ran the same as every other manufacture.

The early Lima chassis again run the other way. These can be taken apart to turn both magnets to get then to run the same way. Again this was changed in the mid 1960's.

There is standard that all model manufactures now use:

This is that a loco will go forwards when + (positive) is applied to the right hand rail.
