What do I mean by standard....in this case lets say the coupling as would be fitted to a "Mintrains" loco, and what do I mean by mod' (ok short for modification!). By this I mean the fitting of a fine piece of wire horizontally above the vertical "pin" on this standard coupling in an attempt to introduce an element of delay to uncoupling-that is to uncouple (here we shall assume that the wagon is fitted with a magnet operated loop), back away from the wagon (to allow the loop to rise above the wire) then move towards the wagon and continue to propel it without it coupling up again.
After all that waffle two queries...first what sort of gap are people allowing between wire and the coupling vertical pin.
Second, can I assume the wire pin protrudes no further than the front of the coupling (common sense?)?
The thoughts of anyone who has tried this system would be welcome-I just know you're out there!
Aiming for Roger Christian, Roger I am told you use this system and that it works very well. Can you advise me?
