It has always puzzled me----No evidence of an uncoupling system on Delta Lines? Considering the era, I presume the uncoupling was done by the 5 finger method??
Kinda sad----the 'O' scale sized cast iron clunky vehicles of THOSE DAYS on Delta Lines distracted from the magnificent craftsmanship of the entire layout.
But Ellison is a true "O' scale hero----I remember him as the man who "did EVERYTHING with NOTHING". His cardstock buildings, artistically decorated, were so admirably "low budget", yet beautiful and effective.
