Your picture looks very much like an Orenstein & Koppel engine - but as it is so small, it is difficult to make out.

I would suggest to reverse the order of the ion exchanger and pH adjustment in your proposed boxcar. Otherwise your exchange resin will be exhausted pretty quickly by exchanging the sodium ions you so carefully added to raise pH. Reducing dissolved solids is not a goal per se - you'll have to blow d...

I've long been hoping that someone would do a systematic calculation now that these computational techniques are easily available. It would be good to experiment with the nozzle - you want to make it as large as possible to reduce the backpressure, yet keep the same amount of smoke gas pumped up the...

Wonderful, absolutely wonderful. The ultimate boy's toys dream

Surely, with all the people getting to drive the model - you got a few meters at the regulator of the full size loco ?

The main issue in France, like it is in Belgium, is that due to privatisation rules, the monolithic state-run railway company was split into several companies, because monopoly rules in Europe forbid that whoever owns and maintains the track also runs the trains. A recipe for disaster if there ever ...

Ph is too broad a term, alkalinity is what you measure for. It roughly corresponds to Ph, but the right kind of alkalinity is helpful, the wrong kind is harmful - kinda like good and bad cholesterol. Hello Marty, Nearly all of what you write makes sense to me, except for the statement above. Would ...

That is very cool - I've just seen it arrive "live" at the yard in Cheyenne - I reckon after now, this feed will be a lot more boring!

Those pictures are works of art.

Now about the chlorine problem At the PLS we have well water no problem there. Just to make the point, since it has not been made in this discussion as far as I could read - it is NOT because you use well water that you are safe from chloride induced corrosion. It is called chloriDE pitting, not ch...

Those pictures are extremely useful - I see now how it can be done. The trick is to have sliding sleepers as well as fixed ones that are just there to support the rail. Excellent. I think the overlapping parts of the rails could be shaped like point frogs - that would further limit the range over wh...

That would be most appreciated. I was unable to find anything in the way of pictures so far.

Thanks!
