"i like this set, i just feel that the new system isn't as good as the old system. i liked it when you could just turn the train on, set it to a speed, and send it off. now, you have to be with it, because if it goes round a wall, it looses signal. also, this uses more batteries and lasts for less time. i have the old system of trains at home, and i use those trains far more often than the new on. I would prefer it if you could go back to the old system."
