sanders' life story. he built it in his house in dallas and, before he died, he taught his daughters, christina and stephaniet. and now they're going to teach me. >> i happen to love trains. are you going to let me try something? >> of course. >> show me how it works. >> okay. pull this lever slowly and we're going to go one after the other. >> all systems go. seems easy, until steve's daughters warn me that his complicated layout demands that the trains run at precise speeds. get it wrong, and i'll crash a couple of very expensive locomotives into each other. yikes! so i'm driving three trains at once. fortunately today, nothing goes off the rails. i love it. i could be here all day. what steve didn't do was instruct his widow, jane, what he wanted her to do with the trains after he died. do you wish he had made these kind of arrangements before? >> well, i wish had, but there just really wasn't the time to even get into it. >> jane estimates steve spent about $1 million on the trains and layout. so perhaps selling off the cars and display, piece by piece, could be just the ticket. enter appraiser laurence
