Good sluething, Santiago! Think the picture of the Chinese Red GP30 was taken in Galesburg. There's a church steeple in the background which, if memory serves, is/was located in Galesburg. The 0-6-0 photo is of one of Burlington's odd-ball reconstructed 2-6-2 to 0-6-0 conversions. Apparently they were pretty good engines, because the last 0-6-0 that worked on the Q was one of them (#565/renumbered 1565; worked in the 1957 Fall rush, in Lincoln).
Hopefully more information will be surfaced !
