Rack loco

What does seem odd is that so many people seem to have had this problem with the small rack loco (23460) and that LGB hasn't noticed itself. You'd think they'd spot in in testing before packing (assuming they do do this).
 
Well im/was a lawyer, not an engineer, but.....

Its powered by one axle*, and the cogs in the rack are not continuosly in contact with the gear, ie theres enough play that as the load increases, so does the jerky engagement of drive wheel teeth into the rack. This is aside from quartering.

Imho, lighter loads, on grade, provides better running.

When i had a rack with about a 15% incline, , i noticed that additional cars really made running, jerky performance, buffer climbing up, increase geometrically.
I run no more than 4 axels.

* I understand that the prototype lgb model had 2 cog wheels, but, it simply couldnt properly mesh, with the rack, i imagine on curves???
