Pennsy A3 Steam issues

[nelsonedgar]

Hi all,
I have built the 3.5" gauge A3 and have been doing some steaming trials. After fixing a number of issues, the A3 runs well but I am unable to maintain running steam pressure, the steam is not being replaced but the pressure eventually drops and I need to use the electric blower again to build up steam. Fellow club members think I may have drafting issues. Has anyone encountered the same problems or do you have advice to give ?
Thanks

Hi nelsonedgar
I have purchased an A3, builder unknown. I have had similar problems and after trying to do several things, came to the conclusion that it was the coal I was using. I switched to Welch coal and it seemed to straighten out the loss of pressure. I haven't tested completely because I had other problems but it scertainly solved the problem of losing steam pressure. Try the Welch coal

Do you mean Welsh coal? As in from Wales in England? I've not heard of welch coal.
