You two are AWESOME!!!
It is a Buchmann train.  It was my brother's and he gave it to my son.  It's got to be 20 years old!
I did the search for Buchmann and they look electric.  Would a Buchmann G train fit on a Lionel G track?  As you can tell I'm not a hobbyist in trains!

Thanks again!

I'm searching for battery operated track (that what the hobby store told me).  We have the battery operated size G train.  A curved part of the track broke.  All I want to do is replace that ONE piece of track and maybe get a few others just in case.  I have call hobby stores and looked on Ebay and can only find electric track.  Should I just give up and wait till next year and ask Santa for a new train?  I have two little kids and we are thinking of having more so I dont want electric track (they like to lick stuff). 

Thanks!
