This version from USA Trains is the heaviest loco to run on the Thurnby track that I can recall.
That would include the Accucraft, Railking and the live steam Aster.
It does give the advantage however that this version is unlikely to slip regardless of what load it is hauling!
You do ofcourse need a fair sized track and check before running that your 'infrastructure' has sufficient clearence.
