In my initial posting I failed to mention the pair of nearly new G-10 0-6-0s that were leased to the FW&D during 1930-31: 588 and 589, freshly converted from R-4 2-6-2s in the Denver shops and oil-burners from the start. See
http://cdm16079.contentdm.oclc.org/cdm/singleitem/collection/p15330coll22/id/68930/rec/1 This Otto Perry photo depicts the 589 about to fuel up at Amarillo, Tex., on Oct. 27, 1930, when the switcher was just six months old. A red fire hose box is mounted beneath the running board at the front of the cab. The pair of switchers didn't stay in Texas beyond 1931 but were returned home to assignment on the Casper Division.
Attached are views of the two oil-burning P-5 Atlantics, also from the Casper Division, that were leased to the Burlington-Rock Island during the 1942-45 period. The 2566 came south first but was quickly replaced by the 2564, and in the summer of 1943 both 4-4-2s were on the B-RI. But by early 1944 the 2566 had been returned and the 2564 remained in Texas through March 1945. About the only likely use for them that I can think of is on the Mexia Branch local out of Teague, as Dallas-Houston passenger trains 1-2 had enough business during the war years that the motor cars on the run were replaced by FW&D or RI light Pacifics. And if they were based at Teague, as seems likely, the Atlantics would not have been in a position to fill in as emergency power on Nos. 1-2. At any rate, we have seen no photos of the pair in Texas, and the attached images are both taken on the storage tracks at the Denver shops, the 2566 awaiting shopping in mid-1941, before it headed south, and the 2566 in early 1948, several years after its return from Texas.
