Yes, I realize why the B6 and the A5 both have tethers, being so short, etc. But the A5 has a regular "hook and slot" coupler which is so much easier. I'm going to look at changing out the B6 to that: certainly have plenty of spare parts in my discarded locos box. The "floppy bar" is unacceptable, particularly since it disconnects upon backing up.There's actually a good reason for the tether. . . . Releasing old stuff as new seems to be the norm rather than the exception nowadays.
