Who knew... The Chicago, Rock Island & Pacific actually made it to the Pacific! I never knew about this pooling arrangement.
Some information on the Trinity & Brazos Valley Railroad which became the Burlington, Rock Island joint line. https://en.wikipedia.org/wiki/Trinity_and_Brazos_Valley_Railway
Not conversant with CRIP Rules for 1933. The B&O Rules I broke in with in 1965 would have this particular order being against the rules for a 19 order. As I recollect any order that was restricting a train at a location was to be issued on a 31 order form (on the B&O 19's were Green and 31's were Yellow - both of a very thin 'flimsy' paper). The order is being copied at the same location that the train is instructed to meet the other train. Under B&O Rules the train getting a 31 order had to be Stopped to receive the order. Timetable and Train Order operations depended upon employees adhering to numerous 'technicalities' to permit SAFE operations.
I do not remember their dispatching scheme. Perhaps someone knows? (Q, then RI, then back to Q?) Was it a year at a time, trading off? Or every six months? or?
I know the Q did all the maintenance every other year, and during alternate years, maintenance basically didn't get done at all. Don't know if dispatching followed that pattern or not.
The Winter 2023 Classic Trains mentioned that the B-RI's Sam Houston Zephyr (No. 3) suffered a locomotive fire on 12/19/1944 at Dacus, TX which destroyed the classic CB&Q shovelnose locomotive and brought the passengers and crew to huddle around bonfires until a relief train arrived. No one was injured. The fire is believed to have started from a fuel line leak. A "baggage coach" and "kitchen" were also damaged. Wikpedia reads that the train was managed by the RI at the time and that they failed to properly maintain the equipment.
Could the baggage section and the kitchen have been in the first car with the locomotive? This photo r_i_straw posted some time ago shows what appears to be one of the kitchen staff looking out of a side door on the first car. https://www.trainboard.com/highball/index.php?media/sam-houston-zephyr.18267/full A somewhat later four-car train: https://www.flickr.com/photos/hunter1828/7040101635
Yeah, it was the in the extended four-car configuration when the fire occurred. To maintain the service after the fire, the B-RI cobbled together a make-up train until the Burlington provided a suitable replacement. The make-up train pictured in the Classic Trains article consisted of a Rock Island P-33 4-6-2, a heavyweight baggage car, a Burlington "Jim Crow" heavyweight coach, a Budd built coach, a heavyweight Pullman sleeper to provide parlor seats to match the normal service and a Burlington Business car to provide meal and lounge service. Eventually the Burlington brought down the E5 Silver Bullet 9909 from the Silver Streak train along with Budd baggage car Silver Light, three Budd coaches, Silver Crown, Chariot and Trail as well as the Observation Lounge car Silver Hours for a permanent replacement train. This set ran until the train was discontinued in 1966.
