I've got couple oof LGB 10304 shuttle units, presumably fairly modern as they have the two potentiometers for adjusting breaking etc. I've got them working on Mode 1 using split track and diodes, but I'd like to try the Mode2 setup which gives more flexibility. However, the split track for this is a special one with a tapped hole in the track itself and without the internal connectors. I only have the standard split track, 1015U. Is it possible to wire up the internal connections on these to replicate the new system?
