I've got a couple of 'Taurii', and am quite happy with them.
If you want to run from overhead power, then the plastic pantographs will need to be replaced. The originals are quite rugged, they've survived being caught by foliage, and simply clip back in.
The directional lighting is a bit poor, a single bulb shines through ( at full track voltage ) a complex moulding to appear as 3 lights. At low speeds, there is just a faint glow. There is a 'drop-in' Massoth board available which has white and red led's, much better. It's a bit pricey for what it is....two boards each with a few leds. A home made version is possible.
In at least one of my examples, the two bogies were not wired together, once this was done running did improve.
I've run mine on undulating track ( min rad 3ft ), and it's fairly happy. I would say it runs as well as most other Aristo/USA/LGB.
Longevity?..yet to be tested. But they are reasonably priced, so buy 1 to run, and 1 as a source of spares?
