At SVRy we have three cars which have a full size coupler on one end and a 3/4 coupler on the other, two are ex EBT hoppers and Caboose #3 is outfitted that way. Along with two modified emergency couplers which fit into the 3/4 couplers we can set up almost any combination of locomotives and cars needed. The planning of photo train consists can be pretty entertaining at times..
