I would like to see if i can get some information on the model railroad operations,i have a 8x8 layout that i have been working on for sometime and i am getting to the point of being ready to start my operation.My question is about the useing of car cards and waybills,i have not seen to much about this but it sounds very interesting to me and i would like to learn more about it.I have been trying to find some information on the internet but not with much help.I am looking for a way to inventory all of my stock and also be able to print out a detail report of everything that i have.I would like to know about routing and what to do with the cars when they are empty.I am not a operator and this is my first layout but i would like to be able to run my layout like the real thing.I would like to know if there is any programs on the internet that you can download to get you started as i have already wrote down some of the books that was listed on here and i am going to see if i can get these from our local libary.{Sorry for the spelling}If anyone could help i would appreciated as i would like to some day be able to share this with my grandkids.please help me with this. Thank You
