- Both the Mk.1 and the Mk.2 magnetic couplings have a more than adequate holding force for a 12-coach train of 160g coaches on a 1 in 50 gradient with reverse curves of radius 4ft and greater. Tests were carried out at scale speeds of 20mph and lower.
- The Mk.2 is easier to use, as identical couplings wll mate with each other. Before the start of the trial it was necessary to change the Mk.1 couplings between the loco and first coach for Mk.2 because one of the Mk.1s was the wrong polarity.
- Further tests are needed to assess the long-term reliability of the adhesive joint holding the magnet to the "pipe", with the stress of regular coupling and uncoupling.
- (Not related to couplings.) An unexplained gap between two lengths of track on a reverse curve has now grown to about 5mm (it was about 3mm in the summer). It is now causing regular derailment and needs investigating.
- (Not related to couplings.) A rail joiner near the top of Quarry Bank has no wire jumper and is not making good contact.
