Count me in for the TWO (2) units. ...
If you agree, chime in and let them know how many units you would buy!!!!!!
Indeed, if Lionel produced multiple road-numbers, I'd buy multiple units.
When Lionel produces multiple road-number diesels, they typically run a prototype road-number powered unit PLUS a fictitious road-number powered unit, and yet another fictitious road-number as a dummy unit. In that case, I would buy all three of these.
When MTH produced their NS Heritage locomotives, they took a different approach -- offering a powered AND dummy in the same road-number, so that folks collecting ALL heritage locomotives could do so true to the prototype without spending big bucks for all powered units. In that case, I'd probably just purchase the one powered unit and forgo the dummy.
