Hi

What options do I have for a HO    H16--44  to reduce the gear ratio and increase traction, for a specific gradient on my layout, about 3%.

Is there a lower ratio gear set available, or complete   trucks with gears  off another model.   Recommendations ??
Is there somewhere that lists gear ratios on different models ?


Thankyou

The square front on the Gs electrics.  Can that be purchased as a spare part ?
