Short Bodied Caboose - for Main Line Service - NOT Transfer service

The following was posted to Trainorders.com on July 21, 2005:
These are not transfer cabooses at all. These are regular road cabooses that the Mopac made hundreds of and they were seen on almost every Mopac train in the 1980s. Not very common for transfer cabooses. They were classed as and used as road cabooses for most of their service life. The 13xxx nunbering signifies mainline road duty and one was even tested by the Union Pacific in the development of their CA-11 caboose which I've never heard called a transfer caboose. International Car proposed the first 50 cars in 1976, saying they could be built at $41,887 a car. MP never actually placed an order with International Car for any cabooses, deciding instead to build the whole roster of "platform-type bay-window cabooses" as they are referred to in the official drawings. These plans were later revised slightly and copied by the UP for their CA-11, CA-11A, and CA-12 class cabooses. Home built in MP's Desoto Shops and finished in the Sedelia Shops, they were the last cabooses built by the Missouri Pacific and lasted into the UP merger, and a few even remain today. The reason they were so small is because they did not need all the extra space, and furnishings that older cabooses had, in turn this saved them money.
