I have an old MTH PS-2, F3 A-B-A, I would like to operate as an A-B. The rear coupler on the B unit is very thin, probably made that way for ease of coupling to the other A unit.
The thin, non operating, coupler will often slide out of any connecting car. I would like to replace the coupler with a standard thickness coupler. It does not have to be operating.
Has anyone done this or know the MTH part number for the coupler?
Thanks, Dan
