Paul,
You can add TMCC, but what I think dgauss is alluding to is it may not be practical to add TMCC controlled electro-couplers to this very small engine. John (gunrunnerjohn) successfully added TMCC to his Williams 44 tonner but did not add electro-couplers because of the difficulty of doing it.
The Williams 44 tonner does have manual operating couplers. After adding TMCC you can operate the couplers the old fashion way using an uncoupling track to operate the couplers. Or you can open them by hand by pushing down on the coupler pin's tab.
