I cannot see any problem, other than as old locos with old motors with high current demand your choice of decoder may be crucial. And getting one into 'Lord of the Isles' may have space problems as well. Try a search on the DCC forum under 'old locos' and see if that brings anything up. 'Triang' might get you something as well.

With most track these days being non-magnetic, 'Magnadhesion' (whereby magnets close to the wheels caused them to grip more firmly on steel track) is of little consequence unless you set out to deliberately buy second-hand steel track. Cleaning steel track and preventing rusting then becomes crucial to maintaining good contact to avoid problems. On the other hand this problem with steel track may be offset by the higher voltage applied by DCC systems.

Ian - the only problem I ever came across with the Magnadhesion was if they picked up particles or pins on the track which shorted out the insulated wheels to the chassis, but this applies equally to the old DC system as well at to the new DCC controls. Just needs a regular check on the loco to see that the magnets are clean.
Can't comment on decoder suitability - I've not moved into DCC myself. Just that I was modelling in my youth when 'Magnadhesion' first came out and have seen earlier postings in the forum on converting the older models.

John
