  1. that seems like a good idea, but on the other hand, keep in mind that the reason the toy gives lettering is because while it moves back and forth it solidifies the letters, where as the train wouldn’t be able to, you could only read a train moving left to right (and not that well), so on the flip side, what about an LED panel ever x feet?
