RI 17099 represents an International Car Company bay window caboose delivered in 1966 as one of several orders of similar cabooses ordered. Rock Island labeled their cabooses "POOL" for those intended for offline use.

The model is an Overland Models import custom painted by TRAIN DETAIL WORKS and is modeled in the as delivered scheme of all red with block lettering. It has had the roofwalk replaced with a photoetched one from Plano and the spare knuckle holder removed from the underframe (thanks Steve Suhs*). A RI style antenna mast was also added.
