However now for my railcars, like the Eureka 620/720s, plus the new Xplorers from Southern Rail and many other passenger cars, I don't particularly want to pull them apart all the time due to the fragile nature of the plastic connection between the cars. However as I don't have a layout and transport them often I can't keep them permanently coupled.
The longest MPD from DCC Concepts is 560mm long and that's unfortunately too short for trains like a two car Xplorer. Is there anything longer length wise in size available here or overseas that can take longer trains so I don't need to couple and uncouple them all the time?
