The Missouri Pacific built their own "platform type caboose car with bay windows"
in their DeSoto, Missouri and Sedalia, Missouri shops and called them Short Bay Window
cabooses. These were the last mainline cabooses for the Missouri Pacific.

The Short Bay Window cabooses were built over a six year period and totaled 351 built.
The last one built was sold to the Texas Mexican Railway, TM 316, and never made it on
the Missouri Pacific roster as a MP caboose.
The Missouri Pacific rostered 350 Short Bay Window cabooses.
