Any Forum member who own a Heljan Class 33 diesel locomotive, find that placing the said model with the exhaust grille positioned to the left of direction, causes the Class 33 to derail on curves and points, while reversing direction of the Class 33, it runs without any fault.
I note that the Class 33 is fitted at both ends with none working screw couplings - can these couplings be the cause for derail? as it looks as possible for this coupling fouling in between the bogy and main body of the Class 33 !! Probably, another fault is causing the derailment+.
Help on this fault will certainly be most appreciated.
