OK, this is my "what if" thread for model railraoding where basically I just list some things that I think would be cool if they happened: 1) What if everyone brought their train sets (or whatever they are officially called) to a sigle place and combined them? 2) What if model there was a millionaire who was really good at and like model railroading? He could like buy a warehouse and make the world's largest train set. Or he could have one going around his backyard. Or a lot of other stuff. What is the world's largest train set anyways? 3) What if there was a device that literally ran your trains for you? Where the trains would run from stop to stop or pick up/drop off cars by themselves from it. You would program it to do certain cycles and for multiple trains it would detect if two trains would crash and correct it. Something like this may already exst, but I don't know. 4) What if we actually put the scale letters in order? sign1 5) What if I could come up with more what ifs?
