That works well, we have replaced the 3/4 couplers on the ends of two of our EBT hoppers (we have six), and on the ends of our two steel flats we received from WP&Y, it gives pretty good flexibility to making up your train. However, we continually look for standard size couplers.!!!!! BTW, #19 will be steamed up for the first time this season May 6. The Heisler is down for at least a month while we removed the front drive line yoke and the eccentric actuation. The key slot is VERY sloppy. Ron Brinton SVRR
