Hopefully a bargain. The seller did contact me after I`d paid though and it seems part of the set is missing.
We`ll see though, and hopefully I can get whats needed.

They are wonderful engines, its a shame they didn't catch on.
They work by superimposing a digital signal on a power feed (20V or 24V I recall) however as shown the control is a nudge of the regulator rather than a servo-signal, so slightly non-intuitive. The smell of steam and oil is traditional though.  I was looking at this very seriously about 10 years ago but it was a bit expensive and I needed the layout to run it on, which I never got near to building.
I have a faint memory of someone changing the controller for a "normal" DCC multi-channel chip to allow more sophisticated control. That worked well.

this fascinates me, how exactly is the water heated, I read on one that is on ebay that electric
is passed through the track to heat the water is that correct?

Yes, that's correct. 
Have Fun

I've spoken with the chaps that run these locos there's a few common problems that people new to operating them don't understand. As a result they have earned a poor reputation when in fact a lot of issues were down to operator error, like allowing the steam to build pressure for one, wrong oil used, (sounds familiar really). My understanding of them is they are DDC controlled via a chip in the loco, the track is powered at 24V as opposed to the 12v which is what makes them incompatible. The piston is housed in the loco along with a DDC chip and displacement lubricator. They as all occilators run better at speed, and a lot of people tried to run them slow, safety valves would blow off and the water would run dry. Earning them a reputation of been poor performers.

Now can someone tell me how to get a myford to regrow metal :)

they certainly look nice Jon, however they sound fairly difficult to get to run
correctly for a novice, as the boilers must be small I can see how they would
easily go over pressure and run dry, certainly a challenge and asborbing type
of steam to get into though

As Rog posted above, the controller is a nudge type. So i think it was three nudges to get ready to set off, then one nudge after 5seconds. The engine would start at a low pace, then as it got running a second nudge would allow full pressure to the cylinders, (voltage to the boiler). Another nudge in the opposite direction would slow the loco, and it would coast, another nudge would cut the steam power. Which brought it to a stop fairly quick. All the time the safety valve was farting away. Two nudges in the reverse position would cut boiler/steam production.

Seeing them run and having it explained showed them running well, even the kids had a go and had them running well 😊 under the watchful eyes of the experts (not me lol)

They look interesting but they are very expensive from what a brief search online demonstrates and it looks like a steep learning curve.

Been looking at rolling roads to avoid having to set up on a large scale.
They look to be very expensive based on eBay completed listings

These live steam engines only seem to be for sale on ebay and they start at £600 :/
