thanks!

I'm frustrated. Recently purchased a Bachmann Norfolk Southern train set for my 8 yr old son.  I bought the 18 piece elevated kit to make the figure 8 layout thinking it would have some sort of track plans in the box but to no avail.  Can anyone help out?  We purchased a few extra pieces just by guessing what we need but I'm not sure. We have 7 straight pieces and a powered straight piece along with 16 of the curved 18inch pieces. I built a table due to room constraints I cut it from the 4'x8' sheet to 4'x6'.  Any help would be appreciated. It's 40 miles to the hobby shop and his birthday is tomorrow. I'm trying to get it up and running. Thanks.
