Following retirement CB&Q Hudson No. 3007 was donated to the city of Quincy, Illinois where it was displayed for a time in Quinsippi Island Park near the Burlington Route's new bridge over the Mississippi River. This post card view, published by Ray E. White of Quincy in 1966, also shows a barge pushing upstream below the bridge. When interest in the Quincy park waned, the locomotive fell into disrepair and was moved to Griggsville, Illinois as part of J. L. Wade's "Purple Martin Train." Subsequently it went on display at Atlantic, Iowa. Finally No. 3007 was purchased at auction by the Illinois Railway Museum where it is now displayed. A remarkable five out of fourteen members of the S-4 class remain, or 35 percent. For the dimensions of this class, see the previous page.
