I recently fitted a Hornby Uncoupler Unit (R8244) which I operate using a Surface Mounted Point Motor (R8243).
The unit works fine except two recently purchased Hornby locos won't pass over the unit - the base of the Class 31 diesel loco is too low and hits the unit and won't go any further; the A4 'Herring Gull' loco will go over the unit but only beacuse the front bogie wheels are lifted up as they pass over.
I have checked that the unit is correctly fitted and ensured that it is in the lowered position before running the locos across!
I assumed that Hornby check that all locos will operate ok with this unit, especially models very recently released.
Can anyone recommend an alternative to the Hornby unit?
Many thanks
