In 1966 Dick Jensen obtained 4963 (along with 5632) as scrap from the CB&Q after the steam excursion program was discontinued. Jensen was evicted from the C&WI roundhouse in 1969, and his equipment was moved to the Erman Howell scrap yard at 83rd street. The 5632 derails during the move into the scrap yard and is scrapped. On March 16, 1991, Richard Jensen, at age 60, passed away. After Richard Jensen's death, the Illinois Railway Museum was able to acquire his 4963, rescuing it from the Chicago-area scrap dealer just before it was scheduled to be cut up. Here are the details. When Northwestern Steel and Wire got rid of its ex GTW 0-8-0s in the early 1980s, the IRM acquired six for its collection (only one was moved to the IRM property). In 1988 the IRM wanted to save 4963 (which sat at that scrap yard until 1990!), and so traded five of the 0-8-0s (8306, 8328, 8372, 8375, and 8379) to the scrap dealer in exchange for 4963. 4963 is now safe at the IRM. It is ironic, that these 0-8-0s which dragged so many fine steamers to their demise in the early 1960s met their end saving a mainline engine from the torch.

In 1923 the ever-frugal Q was planning to increase the water capacity of a number of its O-3 and M-2/M-2-A engines by lengthening their tenders, so it had Baldwin deliver new O-1-A Mikes 4940-4999 with tender underframes long enough to fit the lengthened tenders of the O-3s and M-2 engines. The underframes were then swapped out as the lengthening was completed, which means most of the 4900's ran for at least a short time with the back porch tenders.

The hoses from the bottom of the tender to the journals of the trucks fed water to the bearings to cool them in the event they overheated (fortunately, water and oil don't mix). Each hose could be disconnected and attached to the other journal of the same truck, if needed.
