I appreciate the PW and MPC conventional control trains. I still have quite a few packed away for the grandkids. But, I like to do a lot of switching on my layout. Command control gives me the ability to operate several locomotives independently. The speed control is remarkable. The remote couplers are a must. Sound is nice, but I don't need it. I don't use smoke (too messy). And who can argue about the play value of the TMCC crane?
