I've been trying without success to get a direct link for this. It is a downloadable Flash file (LittleChildren_Trlr1_750_dl.flv) size 9.6 mb. and it is really quite suspenseful. I used to love trains as a little child myself. Now all of a sudden I'm scared.

Maybe somone more resourceful than I, [editman , Nance ...someone!] can get the direct link out of the official site
