Good solution, nicely executed. Keen to see results of steam tests

First run with the modified exhaust and it's a success!

Lovely controllable performance. The only thing we couldn't share was the aroma of coal fired steam!

Do you leave the exhaust valve slightly cracked all the time? Tim

Beautiful and very realistic looking engine!! Its a total shame that he will not ship over to the USA/Canada. I think its time for someone over here to built the same kind of boiler set up for a couple of the Roundhouse chassis an sell them affordably. Most coal fired engines over here seem to be tempermental and for the super well endowed in the wallet to buy. For that matter, since the new Mgmt at Roundhouse is going places never gone before like the double Fairlie, maybe its time for Roundhouse to build something like this in house. Then us Yanks can get a coal fired engine that runs as well as these Riverdale boilered engines do. I would build a coal fired Billy if those boilers were available to me. Keep up the excellent modeling with Smokey Sophie! Mike

I had in mind to connect the valve to a servo or push rod to adjust it (valve closed when building the fire and then adjusted as the run went along) but I have found I don't need to do this as yet and just leave it open slightly.

Thanks for the comments guys, she is so easy to fire (If I can do it anyone can).
Coal firing at least with a Riverdale boiler is not a dark art...

It's an amazing example of what can be done by a skilled enthusiast at home with commercially available parts. The Roundhouse/Riverdale/SSP combination yeilds an impressive machine, but you deserve a lot of credit for the tasteful execution. Everything is very tidy. I especially like the cab fittings.
I'm curious about the "pop" safety valve you've got. All the ones I've seen make a raspy, impolite sound, but yours is almost silent.
