Linn,
If I recall correctly, and this was many years ago, #20 was being pulled up the grade through the cut, and over the fill. This is where the west switch is for the runaround track. There is a "tight" left hand curve there where the blocks were placed. After being pulled onto the runaround track, #20 was pushed out unto the stub ended display track it sat on until it was moved for transport to Strasburg. Again, my memory is a little fuzzy, but I think thats the way it was. #20 was moved several times to excercise it and was moved on the main under the water tank coupled to Rico for a night photo session. It was kept off the curve. This was after the loop was completed. I agree the firebox welds were adequate, but they looked terrible. We've noticed on the RGS equipment we have. 20, Geese, etc. Some of the welding is great, nice puddling, smooth beads, etc. And others are horrible. Goose #7 is a good example. Pro welding on the frame, but on the front "suspension" and the pilot the welding is sloppy and dangerous.
My diagnosis and evaluation of 20's condition is suspect. That's why it went to the best steam rebuild facility with the best director in the country. 346's rebuild was wonderful, 20's should surpass it! Now that you have your feet wet, we still have #318. (I never said that)
Keep doing what your doing.
