I was working on body-mounting couplers the other day, and was surprised to see that the new-ish Microtrains 3-dome tank car does NOT take the standard 1027 body-mount coupler. I haven't yet figured out what fits (I was doing 1027s, so I just went on with that) - maybe the 1015?
Are folks aware of any other MT car (that isn't already a body-mount) that uses something other than the 1027?
