Pete et al, I've only been getting a few occasional messages at the moment (due to house renovations) but I just want to make some comment here about coal (and...
... [cue true/silly story] Some years back was visiting Open Days at nearby Live Steam. Noticed one visitor, from _Canada_, arrived in Mini, unclear as to...
Hi Andrew, Would it be a fair thing to say then that a Lempor ejector, evidently like a GPCS, works spectacularly well when operated as per the design...
G'Day Bruce, there was a 7.25in miniature at the Birdwood Mill which ran on gas, the tender having a barbeque bottle hidden away under the drivers' mat. the...
Not in my experience running tests on a 7-1/4" miniature loco. Once I had the inter-nozzle angle right, the more steam flow through the system the more vacuum...

Hi Ben, ... Zealand in the mid nineties (no idea about how that venture has fared subsequently?), but you could count the number of places to refill on your ...
Hi Benjamin, If a Lempor is replacing a conventional chimney , and the change is only that it would be a fair statement to base the calculation on. However,...
... [OP ***] I believe it's very multi-facetted, ranging from psychological content of the operators/maintainers, right through to pure tech considerations...
Bruce, Very true, and *IF* LNG is available, the use it, by all means. But some countries don't have (cheap) LNG, as we do (or could friggin' do, if the...
Oz Pete, Historical locomotives would do fine with a change to a multiple blastcap only, if the chimney is long enough, L>2D. The vacuum needed would be...
Jos, The reason I view any substantial change to K1 (as an exceptionally historical example) is that it is the world's ONLY existing, and running, 'first go'...
We need to preserve examples of our mistakes as well as our victories - if for no other reason than to avoid making historical mistakes all over again. ...
Dave, 100% agreed...there are more lessons in the errors than there are in the successes. The latter are 'mere' verification of hypothesis, though noteworthy. ...
Oz Pete, Being president of the dutch heritage tramway society also means that I have had the opportunity of being trained in heritage "theory". There is a...
G'Day Alan, Thanks for the update, more or less as one might expect. CNG buses have become sexy in some Aus cities trying to go visibly green. From those I...
Pete et al, It appears that you're stuck in the past with coal and not thinking outside the box when it comes to new technology development. Coal CAN be used...

Hi Andrew Picking on one of the points you mention. If the front end has been designed for an operational limit, which is below that of it's full potential,...
G'day Bruce, Coal bed methane is natural gas in situ. There were some experiments in using enzymes to effectively eat the coal and fart methane, but so far the...
Bruce, As we speak, all your points are very valid, excepting that I hear the rate of Chinese coal-fired powerstation commissioning is as large as those...
Jos, I never questioned your credentials re heritage status of exceptionally historic items, and I do hope those charged with the preservation of such...
Gday All AFAIK, the original modified fitting was a double Lempor and an ex South African Railways oil burner, as well as putting 6 narrow rings on each valve...
Sounds as if a better grade of valve oil, or better lube distribution, combined with shorter elements might have solved these problems and kept her operating...
G'Day Russel, The reason for LNG being more prone to starting equipment fires than LPG (and then more so for H2) is the greater ease with which the smaller gas...
Oz Pete, As built would mean that a builder supplied orifice was used for the early test rides which could be changed for another. Quite often at least 3...
Hi Dave, Imho it also shows that the people that made these combined changes did not have a clue for their combined effect. Why don't we call shit "shit"...
