Hi Soonerfan !
I agree with Shamus - regular Athearn locos (vs Genesis) are nice and rugged (for a plastic model!). However, you might want to buy the loco individually instead of as a "set" of loco and cars - I got a Athearn "set" a while back, and the loco is a poor performer. The cars ("rolling stock") also seems to be of lesser quality.
On the other hand, my "non-set" RI SD40-2 keeps right on rolling, and I'm happy with the other Athearn rolling stock kits I've bought.
As Alan and others pointed out to me on a recent thread, you might want to keep (or put on) horn hook couplers. More sturdy for kids to use. Eh...do you want some ?????
As the kids get bigger (or just for YOU), you might get some "top of the line" locos and rolling stock -
I again agree with Shamus about the Atlas and Kato - but also think LifeLike's Proto 2000 line, or "P2K" is great (do NOT buy the "regular" LifeLike stuff - very childlike stuff! And don't even think about Model Power!). The Stewart locos are also tops. Maybe also the Athearn "Genesis" line - will let you know, as I have one on order!
In top-of-the-line rolling stock (and adult couplers), try Kadee.
Hope this has helped - have fun shopping and building and running!
By the way - Rock Island locos and cars look best on a layout!
